In recent years, the concept of nutrient removal/recovery has been applied as a sustainable solution to develop and design various modern wastewater treatment technologies for recovering nutrients from waste streams and is one of the high-priority research areas. Forward osmosis (FO) technology has received increasing interests as a potential low-fouling membrane process and a new approach to remove/recover nutrients from wastewater and sludge. The main objective of this review is to summarize the state of FO technology for nutrient removal/recovery from wastewater and sludge in order to identify areas of future improvements. In this study, nutrient removal processes, FO membrane technology, main factors affecting the FO process performance, the source water for nutrient recovery, the previous studies on the FO membrane process for nutrient removal/recovery from wastewater and sludge, membrane fouling, and recent advances in FO membranes for nutrient removal/recovery were briefly and critically reviewed. Then, the proposed possible designs to apply FO process in conventional wastewater treatment plants (WWTPs) were theoretically presented. Finally, based on the gaps identified in the area, challenges ahead, future perspectives, and conclusions were discussed. Further investigations on the properties of FO associated with real wastewater, wastewater pre-treatment, the long-term low fouling operation, membrane cleaning strategies, water flux and the economic feasibility of the FO process are still desirable to apply FO technology for nutrient removal/recovery at full-scale (decentralized or centralized) in the future.

Phenol can be one of the main toxic pollutants in wastewater streams from the petroleum industry and other industries such as coal processing, textiles, pharmaceuticals, plastics, wood production, and paint which can be difficult to decompose and can resist to biodegradation. Direct biological treatment cannot be feasible for wastewaters with higher concentration of phenol. Therefore, it is necessary to find an efficient treatment technique to degrade phenol in wastewaters to comply with standards. In this chapter, historical background, fundamentals, classification, reactor designs, industrial applications, and commercialization of supercritical water oxidation (SCWO) technology are reviewed. In addition, reaction pathways and kinetics for phenol oxidation in supercritical water and non-catalytic and catalytic SCWO of phenol in the petroleum industry and other wastewaters are discussed.

Generally, the compliance with the effluent quality standards, the related harm prevention on the surrounding environment and human health, costs reduction, possible water reuse, energy and resource recovery and environmental impacts issues have been the driving forces and/or important criteria in the design and simulation of WWTPs. To date, not much research has been conducted to study the reliability and resilience of WWTPs. This study seeks to provide a comprehensive procedure framework to design the future energy-efficient, cost-effective, reliable, resilient and sustainable full-scale wastewater treatment plants (WWTPs) for both normal and natural hazards conditions. It is a key and emerging research area. In this study, process flow diagram of a typical municipal WWTP, modeling of WWTPs, computer programs for WWTP design, and the previous studies on the simulation of the full-scale WWTPs were briefly and critically reviewed. Then, the procedure framework was presented. Finally, future perspectives and conclusions were discussed.

The increasing demand for energy all around the world has led to a rise in greenhouse gases (GHGs), of which carbon dioxide (CO2) is the most important. CO2 is largely responsible for global warming and climate change. Processes such as carbon dioxide capture and storage (CCS), which have an effective role in climate mitigation, seem to be promising. In recent years, porous carbons, particularly activated carbons (ACs), have rapidly emerged as one of the most effective adsorbents of CO2. However, the implementation of pristine ACs in the real world is still hindered due to their physical and weak adsorption, which makes these adsorbents sensitive to temperature and relatively poor in selectivity. Hence, the surface modification of ACs is essential in order to improve their surface area, pore structure and alkalinity. Numerous studies have reported lignocellulose-based ACs as very promising adsorbents of CO2. In this review, the sources, health and environmental effects of CO2, and the abatement methods of GHGs are described. In addition, the capture and separation of CO2 from gas stream using various types of lignocellulose-based ACs are summarized. Furthermore, the key factors controlling the adsorption of CO2 by ACs (characteristics of adsorbents, preparation conditions, as well as adsorption conditions) are comprehensively and critically discussed. Finally, future research needs and prospective research challenges are summarized.

Organometallic compounds can widely be applied as reagents in the production and processing of new and advanced inorganic substances, as catalysts or precursors in preparation of different chemicals, and as chemotherapy drugs or in the design of novel medical therapeutics. Solubility data of the organometallic compounds in the supercritical fluids (SCFs) are required for establishing optimum operating conditions and designing of SCF processes. In addition, better knowledge on the dissolution phenomenon can be provided by mathematical modeling of organometallic compounds solubility in SCFs. Furthermore, solubility modeling can provide an approach to estimate solubility at different operating conditions with a minimum of experimental data. All this can enhance the development and progress rate of an SCF process. In this chapter, types of organometallic compounds, their solubility in supercritical carbon dioxide (SCCO2), measurement techniques, variables affecting solubility, recent developments, and thermodynamic modeling (model based on regular solution theory, empirical models, and equations of states (EOSs)) are discussed.

Treatment of the petroleum refinery wastewater containing complex chemicals using biological processes is usually challenging because of the inhibition and/or toxicity of these matters when they serve as microbial substrates. In addition, performance modeling and cost evaluation of processes are essential for designing, construction, and forecasting future economic requirements of the petroleum refinery wastewater treatment plants (PRWWTPs). In this study, the performance and economics of conventional activated sludge (CAS) process replacing by sequencing batch reactor (SBR) technology in a two train PRWWTP were evaluated using simulation. The final treated effluent characteristics for the PRWWTPs containing CAS + CAS and SBR + CAS processes under steady state conditions were studied and evolution of the main parameters of the final effluent during the 30 days of simulation for these plants were investigated. Finally, the total project construction, operation labor, maintenance, material, chemical, energy, and amortization costs of these plants were estimated and compared. Results demonstrated that the project construction cost of PRWWTP containing CAS + CAS processes was lower than that of PRWWTP containing SBR + CAS processes and the energy and amortization costs for both plants were higher in comparison with the operation, maintenance, material, and chemical costs. Note that this study is a computer simulation and drawing general conclusions only on the basis of computer simulation may be insufficient.

Design of an optimum adsorbent for carbon dioxide (CO2) capture is likely one of the most important challenges of our time. In the present study, we report for the first time the fabrication of walnut shell-derived nanoporous carbon with chemical adsorption sites for CO2 adsorption at mediate (1 bar) and high pressures (10 bar) under room temperature by varying the preparation parameters. Based on the results, KOH activation through reaction with N groups of urea results in a great development of the pore structure, furthermore micropores are formed better by decreasing KOH/C mass ratio and activation temperature, and increasing the activation time, which cause higher adsorption at 1 bar. However, contrariwise conditions can form mesopores, leading to higher adsorption at higher pressures. Consequently, the value of CO2 adsorption capacity reached 7.42 and 14.03 mmol/g under optimum conditions at 1 and 10 bar, respectively. It was found that the CO2 adsorption capacity is dependent on both the nitrogen loading amount and the porous properties of adsorbent, and in specific the average pore diameter showed more effective role than surface area. Finally, the optimum adsorbents with heterogeneous surfaces and interactions represented promising choices to separate CO2 from CO2/CH4 and CO2/N2 binary mixtures.

Catalysts (homogeneous or heterogeneous) can be utilized to improve the performance of conventional advanced oxidation processes (AOPs). In general, catalyst activity, selectivity, stability, simplicity of preparation, preparation time, cost, nontoxicity, availability, recycling capability, environmental suitability, etc. can be the important parameters in the catalyst selection. High costs, cumbersome preparations, and environmental unsuitability can usually hinder the industrial applicability of a catalyst. In this chapter, catalytic AOPs (Fenton-based processes, catalytic ozonation, heterogeneous photocatalysis, catalytic wet air oxidation, and catalytic supercritical water oxidation), related catalytic materials, and cost-effective catalytic materials used in these processes are discussed.

In this study, a simple, rapid, low cost, sensitive and environmentally friendly technique, supramolecular solvent microextraction (SM-SME) followed by high performance liquid chromatography-ultraviolet has been proposed to extract carbaryl from water samples. Parameters, affecting the SM-SME performance such as the weight of decanoic acid (DeA), volume of tetrahydrofuran (THF), pH and salt concentration, were studied and optimised. The effect of the pH on the extraction efficiency was evaluated by one–factor-at-a-time methodology, but the other variables were optimised by a face-centred cube central composite design methodology. Optimum extraction conditions were obtained: DeA: 70 mg; THF: 650 µL; salt concentration: 10% (w/v) NaCl and pH = 2–4), and the performance of the proposed method was evaluated. Under the optimum conditions, good linearity (1.0–500 µg L−1, r2 = 0.9994) was obtained. Limit of detection and limit of quantification were 0.3–1.0 µg L−1, respectively. Also, the recoveries of the carbaryl were obtained in the ranged from 96% to 105%. Finally, proposed method was successfully applied for the determination of the carbaryl in the water samples of farms run-off and rivers and satisfactory results were obtained.

The activated sludge (AS) process is a type of suspended growth biological wastewater treatment that is used for treating both municipal sewage and a variety of industrial wastewaters. Economical modeling and cost estimation of activated sludge processes are crucial for designing, construction, and forecasting future economical requirements of wastewater treatment plants (WWTPs). In this study, three configurations containing conventional activated sludge (CAS), extended aeration activated sludge (EAAS), and sequencing batch reactor (SBR) processes for a wastewater treatment plant in Tehran city were proposed and the total project construction, operation labor, maintenance, material, chemical, energy and amortization costs of these WWTPs were calculated and compared. Besides, effect of mixed liquor suspended solid (MLSS) amounts on costs of WWTPs was investigated. Results demonstrated that increase of MLSS decreases the total project construction, material and amortization costs of WWTPs containing EAAS and CAS. In addition, increase of this value increases the total operation, maintenance and energy costs, but does not affect chemical cost of WWTPs containing EAAS and CAS.
