Biodiesel production calls for innovative solutions to turn into a competitive process with a reduced environmental impact. One of the process bottlenecks stands in the immiscibility of oil and alcohol as raw materials, so mixing process largely impacts the overall process cost. This process step, if carried out by using hydrodynamic cavitation, has the possibility to become a benchmark for large scale applications. In this paper a process analysis of biodiesel production scheme is developed starting from two different feedstocks, virgin oil and waste cooking oil. At the first the traditional process scheme has been simulated, in a second simulation, the reactor for the biodiesel production is interchanged with a hydrodynamic cavitation reactor. In the paper, the comparison between the traditional and innovative process by using life cycle costing approach has been presented, thus providing indications for industrial technological implementation coming from a professional tool for process analysis. It is worth noting that the introduction of hydrodynamic cavitation reduces of about 40% the energy consumption with respect to the traditional process. As regards the total treatment costs, when using virgin oil as feedstock, they were in the range 820–830 €/t (innovative and traditional process, respectively); while starting from waste cooking oil the costs decreased of about 60%, down to 290–300 €/t (innovative and traditional process, respectively).

Hydrodynamic cavitation (HC) has been extensively studied for the Advanced Oxidation of organic compounds in wastewaters since it physically produces an oxidative environment at ambient conditions. This process is simple and economical since it can be realized through a properly designed restriction in a pipeline, even in retrofit solutions. Several experimental works individuated similar values of the optimal operating conditions, especially with regard to the inlet pressure. Up to now, the available modeling works rely on a single-bubble dynamics (SBD) approach and do not consider the actual process configuration and pollutant transport in proximity to the oxidizing environment. This work describes different experimental results (from this research group and others) and applies a novel mathematical model based on a transport-phenomena approach, able to directly simulate the effect of HC on the pollutant degradation. The novel proposed model is able to reproduce well a large number of experimental data obtained in different conditions, with different apparatus and different molecules, and allows to interconnect both SBD, fluid-dynamics, and physio-chemical variables in order to deeply study the interaction between the transport of pollutants and the reactive environment. This paper includes collection and discussion of several experimental results with the related main process parameters, description of the novel model and validation against the cited experimental results (to explain the effect of the operating pressure), sensitivity analysis, and the performance limit of the HC with the proposed modeling approach.

Tetramethylammonium hydroxide (TMAH) is widely used as a solvent in the semiconductor industry. After the photo-impression process, it is necessary to remove the photoresist (PR) layer from the surface of the circuits; for this purpose, a TMAH solution is usually used. This chemical compound is highly toxic and corrosive and cannot be discharged into the environment. This study was carried out in collaboration with LFoundry (SMIC group), in order to prove the feasibility of biodegradation under aerobic conditions, using microorganisms coming from the LFoundry’s wastewater treatment plant (WWTP) at different operating conditions. The feed composition was modified in order to add a small but increasing amount of TMAH and PR. The aim was to verify if the increase of TMAH concentration was harmful to bacteria. The feed stream, containing TMAH and PR, was the only carbon source for the metabolism of the aerobic microorganisms. The results of this study demonstrated an effective biological degradation of TMAH and showed a total removal efficiency of more than 99.3%, with a final concentration of 7 mg/L. Moreover, the kinetic parameters of the Monod model were also calculated. The results obtained from the experimental campaign were used to design a pilot plant that will treat around 25 L/h of waste TMAH/PR solution.

The control of fouling and scaling on heat and mass transfer surfaces is of major importance in processes as superficial water treatments, since it also improves the efficiency of the whole process from an energy saving point of view. The aim of the paper is to present the experimental results obtained in the inhibition of the fouling and scaling by calcium ions on an ultrafiltration membrane surface, by using citric acid as an additive. The last is an environmentally friendly additive−a so-called “green additive”, which may represent a reliable alternative to phosphorous and nitrogen based compounds typically used as inhibitors, since it has the characteristics of being non-toxic, non-bio accumulating, and biodegradable. The experimental plant is made of a tangential flow system on a lab scale equipped with a flat sheet ultrafiltration polymeric membrane, whose cut-off is 650 nm. In the first series of experiments, the effect of water hardness and its fouling effect due to calcium ions on membrane permeability has been measured in the range of potable waters. Then, the scaling effect of high calcium concentration in solution (supersaturated conditions) has been quantified by measuring the increase in weight of the membrane, with and without the addition of citric acid as an additive; moreover, the retarding effect of citric acid has been evaluated through the measurement of the induction times for the nucleation of calcium sulfate dihydrate (used as model scalant for fouling). Experiments have been carried out at two different supersaturation ratios (S = 2.25–2.60), at room temperature, in the absence of any additive, and with a citric acid concentration varying in the range 0.01 to 0.50 g/L. Experimental results have shown that the addition of citric acid in solution delays the induction times for gypsum crystals nucleation; moreover, it mitigates the phenomenon of membrane fouling and reduces the pressure drops by allowing an acceptable permeate flow for a longer duration.

The microelectronics industry produces significant amounts of wastewaters containing inorganic substances such as fluorides, phosphates, and organic pollutants such as acetic acid (CH3COOH), and tetramethylammonium hydroxide (C4H13NO, TMAH). The objective of this manuscript is the description of the depuration process of three types of wastewaters, representative of real liquid wastes coming from a multinational company of semiconductor production. The first residual liquid flow (WW1) contained TMAH, the second one (WW2) contained fluorides and phosphates, while the last (WW3) was rich in nitrates, fluorides and acetic acid. Aerobic treatment of WW1 was investigated by using a lab scale reactor inoculated with an activated sludge coming from the company municipal wastewater treatment plant. Another residual industrial effluent (photoresist) was added, together with several micronutrients, to guarantee a good carbon/nitrogen ratio and a nutrient supply for bacterial growth. The results showed that after one day of acclimation, the microorganisms started to remove TMAH and 99% of degradation was reached in seven days. For WW2 and WW3, a pollutant removal of 99% was obtained by chemical precipitation with lime. An attempt was made to implement the research progress made on the laboratory-developed process at the pilot and industrial scale. To this end, a simulation of the combined process was performed by using a specific software, SuperPro Designer. The process analysis showed that the treated liquids, containing TMAH not degraded to trace levels and other residual substances, can be sent to the biological WWTP of the company for further treatment; after that, the treated water can be reused and/or discharged to surface waters.

In this paper, Triclosan (5-chloro-2-(2,4-dichlorophenoxy)phenol; TCS) photodegradation is studied by using a lab-scale experimental apparatus with a parametric variation study. Experiments were performed by using a lab view experimental set-up, consisting in a batch reactor (Petri dish) irradiated by UV-light at a wavelength of 254 nm and an UV dose of 400 mJ m−2. The effect of Triclosan initial concentration (TCS0), irradiated solution volume (V), solution initial pH (pH), nitrate anions (NO3−) and humic acids (HA) as a function of the irradiation time (0–60 min) is investigated, in order to study both direct photolysis and the combination of direct and indirect photolysis. Furthermore, TCS heterogeneous catalytic photolysis is studied when titanium dioxide (TiO2) is added to the experimental solution. The main obtained results have shown that TCS removal seems not to be significantly affected by TCS0 and V, while pH, NO3−, HA and TiO2 appear to be effective for TCS degradation; in particular, TCS photodegradation is enhanced by titanium dioxide. Finally, photo-oxidation by-product identification was performed, by determining 2,8-DCDD and 2,4-DCP as TCS photolysis reaction products, and a photoreaction pathway has been proposed, which allowed to assess TCS photolysis degradation rate constants, 2,8-DCDD and 2,4-DCP generation rate constants.

The aim of this research was to investigate the methyl orange degradation using hydrodynamic cavitation. The synthetic solutions simulated a real textile effluent containing dye and metals (iron and nickel) as a consequence of the corrosion of nickel-plated metal components of the plant during the production of textile materials. In the first series of experiments, the hydrodynamic cavitation was studied in terms of operating inlet pressure and pH of solution. Subsequently, a full factorial plan was performed to determine the main effects and interactions among the investigated factors: inlet pressure (pin), temperature (T), initial dye concentration (cMO/0), and treatment time (t). The results showed that inlet pressure, temperature and concentration had a significant positive effect on dye degradation, as well as the interactions temperature/dye concentration and pressure/time. The optimum operating conditions among those investigated were: cMO/0 = 5 ppm, pH = 2, pin = 0.6 MPa and t = 1 hour, independently of temperature (T). In the above conditions, the degradation yields were near to 75% and the final concentration was less than 1 ppm. On the contrary, at cMO/0 = 20 ppm, pH = 2, pin = 0.6 MPa, 40 °C and t = 1 hour, the degradation efficiency was about 56% and the final concentration was less than 9 ppm. A comparison among the experiments carried out in the absence and in the presence of iron and nickel showed that metals acted as catalysts and the energy required for the process with metal ions was 5 times smaller than those required by the experiments conducted without the metals in solution, at the same operating conditions.

An advection–diffusion–reaction transport model for a continuous reactor characterized by a simple geometry is simulated to provide a design guidance for the realization of an optimized experimental prototype consisting of a rectangular channel hosting a scaffold slab that provides an immobilizing support for the cells. A counter‐current carrier flow crossing the channel feeds the oxygen and growth factors and ensures the removal of metabolic products. A more complex sinusoidal configuration, which has been recently used as for hepatocyte culture, is proposed and evaluated. Silico tests shows how the designed device is able to replicate the endothelial–parenchymal interface of a liver sinusoid.

In this article, removal of cobalt ions from synthetic liquid wastes aimed at surfactant and water reuse was carried out using a micellar-enhanced ultrafiltration (MEUF) process, adding an anionic surfactant (sodium dodecyl sulfate or SDS), with a lab-scale ceramic ultrafiltration membrane. In the first part of the study, ultrafiltration was studied to define the removal yields of cobalt from initial solutions. During these experiments, the effect of membrane size (1–210 kDa) and surfactant concentration (0-4-10 mM) was studied. Results showed a positive effect of surfactant on removal efficiency; maximum yields (>90%), with an initial cobalt concentration of 9.7 mg/L, were obtained by using the highest level of surfactant. After ultrafiltration, separation of metal and recovery of surfactant was carried out by acidification with sulfuric acid followed by another step of ultrafiltration. Results of the second series of experiments showed that separation yields for cobalt >96% could be obtained after acidification to a pH = 1. Regarding SDS recovery, as a consequence of acidification, the pore size of the membrane was enlarged so that SDS micelles could pass through the membrane, resulting in lower yields with respect to metal rejection. In this article, hence, the technical feasibility of MEUF combined with acidification to remove heavy metals and recover surfactant was demonstrated. This last step is important to reduce the high operative costs due to the use of surfactant.

In this research, micellar enhanced ultrafiltration (MEUF) is tested as a seawater pre-treatment before entering RO. The experimental tests were performed by means of monotubular ceramic membranes of 210 kDa and 1 kDa. Boron is removed from the water flow using sodium dodecyl sulphate as a surfactant. The synthetic solutions contain 5 mg/L of boron and SDS concentrations are equal to 1.15 g/L and 2.88 g/L, under and above the critical micellar concentration, respectively. Experimental data showed that MUEF is efficient in removing boron, with best performances obtained at low pressure, with a low or null surfactant concentration for 1 kDa membrane and a high surfactant concentration for 210 kDa membrane. Moreover, experimental results have been used to perform a preliminary process analysis for a hypothetic sea-water desalination plant, with MEUF as a pretreatment for the RO section. The results showed that the MEUF guarantees a boron concentration after RO below the allowed threshold, by using a single step osmosis; moreover, in this way it was possible to reduce the energy consumption thus resulting in an appreciable reduction of carbon footprint as well as of the unit cost of water

Diclofenac (hereafter DCF) is an extensively used anti-inflammatory drug; therefore, it is found in many sewage treatment plant effluents and it is one of the most usually reported environmental pharmaceutical contaminants. In this work, the degradation of diclofenac in pure water under UV light was studied, and the influence of some variables, such as humic acids (HA), nitrate anions (NO3−) and titanium dioxide (TiO2) on DCF photodegradation was investigated. The experimental activity was carried out in a batch reactor of 100 mL equipped with fixed UV light of 254 nm and an irradiation intensity of 400 mJ/m2. Diclofenac initial concentration was equal to 10 mg/L in pure water, and its removal was evaluated by varying HA concentration in the range 10–20 mg/L and NO3− concentration in the range 25–50 mg/L. Furthermore, the heterogeneous catalysis with TiO2 (1–50 mg/L) was studied. Temperature in all experiments was kept constant at 20 °C. Experimental results show that while HA have a significant influence on DCF photodegradation, nitrate and titanium dioxide seem to be ineffective, at least in the tested conditions. Finally, DCF photolysis modelling was carried out and a pseudo-first-order kinetic model was used.

In this paper, the separation of tetramethyl ammonium hydroxide (TMAH) from synthetic liquid wastes of electronic industry is carried out by using a micellar enhanced ultrafiltration (MEUF) process. This treatment represents the first step of an integrated process, aimed at the recovery of TMAH and surfactant and water reuse. The laboratory tests are carried out with an ultrafiltration module using initial solutions having a concentration of pollutant equal to 2 g/L and by adding sodium dodecyl sulfate as a surfactant, at a concentration in the range 4–10 mM/L, that is, under and above its critical micellar concentration (CMC). The experiments have been carried out at a fixed temperature of 25°C. The obtained results showed that very good percentage removals of TMAH are achieved (99%), especially when the surfactant was above the CMC.

Acrylic paint, notwithstanding the attention paid during the production process, couldbe contaminated by bacteria. This is a consequence of microbiological residuals on the can, resulting in the alterationof paint characteristics. It is therefore necessary to provide an in-canpreservation of the paint by using a biocide.In this paper, the evolution of an in-can system, using a thermo-fluid dynamic model is presented; as a biocide, 2-methyl-4-isothiazolin-3-one, commercially known as MIT,was considered. The model was implemented on gPROMSsoftware and it was possible to determine the inhibitory concentration of the biocideinorder to guarantee both the protection of the can and the protection of thecover phase. To develop the model, kinetic parameters have been found by fitting available literature experimental data. As far as the thermodynamical parameters, theequilibrium between liquid and vapor phases was described bythe NRTLmodel (ASPEN Plus). The model has been validated through a comparison with experimental literature results using MIT alone and a mixture of biocides (MIT/BIT). The main results are that,at the maximum allowable concentration (100 ppm as imposed by law), the MIT biocide is able to protectthe paint for long periods, even when the temperature varies cyclically from 10 to 40°C

In this paper, the six more poisonous species among all congeners of dioxin group are taken into account, and the P-T diagram for each of them is developed. Starting from the knowledge of vapour tensions and thermodynamic parameters, the theoretical adsorption isotherms are calculated according to the Langmuir's model. In particular, the Langmuir isotherm parameters (K and wmax) have been validated through the estimation of the adsorption heat (ΔHads), which varies in the range 20-24kJ/mol, in agreement with literature values. This result will allow to put the thermodynamical basis for a rational design of different process units devoted to dioxins removal.

The reuse of wastewater is a key factor in a closed water cycle approach, in which wastewater is treated and then reused. This approach is both mandatory for the development of dry areas and necessary for the sustainability of industrialized countries in terms of environmental impacts and resource preservation. Although there are some virtuous examples of water reuse projects in the world, there is still much to be done, especially in terms of incentives and economic viability. Aim of the present paper is to give thermodynamic and engineering elements in order to develop an economic incentive to promote wastewater reuse and to adopt the closed water cycle approach. At this scope a techno-economic analysis of the civil wastewater depuration and reverse osmosis treatment of the secondary effluent is presented, by using the typical approach of the chemical engineering. The cost of the treated water in relation to the fundamental parameters of the plant is calculated together with an “energy based” incentive, evaluated through the efficiency of the state-of-the-art desalination process. This last can make a reuse project economically feasible on the basis of rigorous thermodynamic considerations. These latter give a universal character to the incentive calculation and also reward the process optimization towards the goal of lowering the carbon emissions. The validity of the proposed incentive method is evaluated through the analysis of three wastewater treatment and reuse projects at different scale. The results show how it is possible to obtain a positive Earnings Before Interests and Taxes (EBIT) for plant productivity above the 200 m3/day, by including the proposed incentive in the Business Plan of the integrated plant of Water Treatment and Reuse.

The advanced treatment of polluted liquid streams containing traces of pharmaceutical compounds is a major issue, since more and more effluents from pharma labs and wastewaters containing the excretions of medically treated humans and animals are discharged in the conventional wastewater treatment plants without previous effective treatments. Ibuprofen is a widely used non-steroidal anti-inflammatory drug (NSAID), which explains why it is found in wastewaters so often. In this paper, the removal of IBP from simulated water streams was investigated by using a lab-scale experimental device, consisting of a batch reactor equipped with a lamp emitting monochromatic UV light at a fixed wavelength (254 nm) and various intensities. Three sets of experiments were carried out: the first to study IBP concentration as a function of time, at different volumes of treated solutions (V = 10–30 mL); the second to explore the effect of pH on IBP degradation as a function of time (pH = 2.25–8.25) and the third to evaluate the effect of different UV light intensities on IBP degradation (E = 100–400 mJ m−2). The IBP initial concentration (IBP0) was varied in the range 30–60 mg L−1. The results obtained show that the concentration of IBP decreases along with treatment time, with a negative effect of the treated volume, i.e. smaller volumes, such as lower liquid heights, are more easily degraded. Moreover, the higher the pH, the better the IBP degradation; actually, when pH increases from 2.25 to 6.6 and 8.25, the IBP concentration, after an hour of treatment, decreases respectively to 45, 34 and 27 % of its initial value. In addition, as the intensity of light increases from 100 to 400 mJ m−2, the IBP concentration decreases to 34 % of its initial value. A reaction scheme is put forward in the paper, which well describes the effects of volume, pH and light intensity on the IBP degradation measured experimentally. Moreover, the IBP degradation by-products have been identified.

Wastewaters from civil and industrial use, which contain high concentration of heavy metals, pose the problem for their correct disposal. They cannot be directly discharged in sewage systems, as metal ions represent a serious problem not only for human health but also for the environment. In this paper, the removal of nickel, cobalt, chromium, and zinc ions from synthetic liquid wastes was carried out, by using a micellar-enhanced ultrafiltration (MEUF) process; an ultrafiltration (UF) membrane (a monotubular ceramic of molecular weight cutoff 210 kDa) together with sodium dodecyl sulfate (SDS) as an anionic surfactant was used, in a lab-scale experimental device. The synthetic liquid contained 10-mg/L metal ions (Cr, Zn, Co, Ni), while SDS concentration varied from values above and below critical micellar concentration (CMC). The experiments were carried out at room temperature (25 °C). Results achieved showed that SDS was able to bind metal ions, resulting in a strong increase of rejection coefficient, which reached highest values in case of SDS concentration below CMC, unexpectedly.

The presence of trace of pharmaceutical compounds (PhACs) in groundwater and in drinking and superficial waters is a major public health concern. Recently, various advanced treatment technologies have been studied to remove these kinds of pollutants; among them, combined treatments based on UV light appear to be more eco-friendly and with very interesting removal efficiencies if properly modified. In this paper, the removal of Ibuprofen (IBP) from synthetic water streams was investigated by using a lab-scale experimental device consisting of a batch reactor equipped with a lamp emitting monochromatic UV light (254 nm; 400 mJ m−2). The IBP initial concentration (C IBP0) was 45.9 mg L−1. Two sets of experiments were carried out; the first one was aimed at studying the IBP concentration as a function of time, at different volumes of treated solution; the second one was aimed at exploring the effect of pH on IBP degradation as a function of time. The results obtained show that the concentration of IBP decreases along with treatment time, with a negative effect of the treated volume, i.e., smaller volumes, that is lower liquid heights, are more easily degraded. Moreover, the higher the pH, the better the IBP degradation; actually when pH increases from 2.25 to 5.51 and finally to 8.25, the IBP concentration, after an hour of treatment, decreases respectively to 45, 34, and 27 % from its initial value. A reaction mechanism is suggested, which well describes the effects of volume and pH on the experimentally measured IBP degradation.
