The aim of the conducted research was to assess the effectiveness of the nitrification process, at different concentrations of ammonium nitrogen, in biologically treated wastewater in one of the largest municipal and industrial wastewater treatment plants in Poland. The studies also attempted to acclimate nitrifying bacteria to the limited concentration of ammonium nitrogen and determined the efficiency of nitrification under the influence of acclimated activated sludge in the biological wastewater treatment system. The obtained results indicate that the concentration of ammonium nitrogen above 60.00 mg·dm−3 inhibits nitrification, even after increasing the biomass of nitrifiers. The increase in the efficiency of the nitrification process in the tested system can be obtained by using the activated sludge inoculated with nitrifiers. For this purpose, nitrifiers should be preacclimated, at least for a period of time, allowing them to colonize the activated sludge. The acclimated activated sludge allows reducing the amount of ammonium nitrogen in treated sewage by approx. 35.0%. The process of stable nitrification in the biological treatment system was observed nine days after introducing the acclimated activated sludge into the aeration chamber.

Phosphorus (P) is essential for life and has a fundamental role in industry and the world food production system. The present work describes different technologies adopted for what is called the second-generation P recovery framework, that encompass the P obtained from residues and wastes. The second-generation P has a high potential to substitute the first-generation P comprising that originally mined from rock phosphates for agricultural production. Several physical, chemical, and biological processes are available for use in second-generation P recovery. They include both concentrating and recovery technologies: (1) chemical extraction using magnesium and calcium precipitating compounds yielding struvite, newberyite and calcium phosphates; (2) thermal treatments like combustion, hydrothermal carbonization, and pyrolysis; (3) nanofiltration and ion exchange methods; (4) electrochemical processes; and (5) biological processes such as composting, algae uptake, and phosphate accumulating microorganisms (PAOs). However, the best technology to use depends on the characteristic of the waste, the purpose of the process, the cost, and the availability of land. The exhaustion of deposits (economic problem) and the accumulation of P (environmental problem) are the main drivers to incentivize the P’s recovery from various wastes. Besides promoting the resource’s safety, the recovery of P introduces the residues as raw materials, closing the productive systems loop and reducing their environmental damage.

This study brings an alternative to treat high ammonium-containing wastewater, presenting a new approach exclusively developed to operate one-stage deammonification process called NITRAMMOX®. The reactor was developed to reduce costs and simplify the operation, promising to be favorable to ANAMMOX and AOB. The correlation between reactor configuration and process efficiency were evaluated using the hydrodynamic characterization, flow anomalies identification, oxygen mass transfer efficiency and reactor start-up. NITRAMMOX® quickly acclimated bacteria after inoculation, presenting a 12-day start-up using 6 h-θ, 25 °C. The hydrodynamic results obtained at different superficial gas velocity (0.40 to 31.8 cm min−1) showed a quick oxygen mass transfer and movement, due to the adequate geometric proportion and reactor design. Deviations from ideality do not compromise the ability of the tracer distribution throughout the NITRAMMOX®, indicating great fluid longitudinal dispersion with no dead zones (θr≥θt), no short circuits (Ψ≤0.3) and good hydraulic efficiency (λ > 0.75), approaching the behavior of a complete mixing reactor. The treatment concept by NITRAMMOX® was shown to be suitable for biomass retention and to establish and favor ANAMMOX bacteria, which can achieve high nitrogen removal rates. The reactor can be applied as a new technology for field application in wastewater treatment systems with low C/N ratio.

This work aims to evaluate the adsorption potential of bentonite and sugarcane bagasse clay for the reduction of free fatty acids in cooking oil through batch technique, experimental planning with different operating conditions (temperature, adsorbent mass and agitation). After were carried out kinetic studies and thermodynamic studies. Thus, both adsorbents were characterized by nitrogen dispersion, scanning electron microscopy with coupled energy dispersion spectroscopy. The sugarcane bagasse provided higher reductions compared to the bentonite clay, 58 and 50%, respectively. In the kinetic studies, it was observed that the pseudo-secunda model for both materials. Among the isotherms studied, the Langmuir model was better adjusted for sugarcane bagasse and Freundlich for bentonite clay. Thermodynamic parameters indicated spontaneous and endothermic adsorption at temperatures of 18°C, 20°C and 25°C. Both materials showed an advantageous result with the reduction to the adsorption of free fatty acids in the residual oil, considering that they are low-cost materials, their pre-treatment is simple from the operational point of view and their physical and chemical characteristics are favorable to the adsorption process, sugarcane bagasse contains about 42% hemicellulose, which is a hydroxyl-rich material that attracts the H+ ions from the medium.

Since industrial wastes are increasing, the development of studies to find ways for their use is urgent. Waste cooking oil is an important source for the production of biodiesel, one of the main biofuels in Brazil. However, during cooking, the oil undergoes conditions that change its properties and decrease its quality, such as its acidity value. Current research treats waste cooking oil by the adsorption process using rice husk, an agro-industrial waste, and activated carbon to compare results. The potential of the adsorbents to remove free fatty acids in waste cooking oil has been investigated by the batch technique, evaluating different operating conditions of temperature, adsorbent mass and agitation. Adsorbents were characterized by nitrogen physisorption, scanning electron microscope, energy-dispersive spectroscopy and X-ray diffraction. The maximum result obtained for activated carbon at acidity reduction was 63%, using 22.4°C, 169.64 rpm and 3.39 g of adsorbent mass. Already, using the rice husk the percentage of removal was the same, 63% using 22.4°C, 80.36 rpm and 1.61 g of adsorbent, however in shorter times. The results prove that the application of the rice husk for this purpose is advantageous, for being a low-cost material, available on a large scale and that provide results similar to activated carbon.

Swine wastes obtained from farming activities have the greatest impact on the environment by environmental agencies. Swine wastes together with poor management represent risks to the environment. In Brazil, these activities significantly increased in the last years and from 2014, the country became the fourth largest producer in the world. Swine wastes are generated in high amounts due to the confinement system used nowadays. This, coupled with the poor management of these wastes is now a serious problem to the environment. Therefore, the treatment of this waste is essential to maximize integration between environment and production. Based on this, the aim of this study is to perform a bibliographic survey of the swine waste treatment used mostly in Brazil and the ones that stand out most. Key words: Swine waste, reuse, environment.

The influence of variables that affect the process of alcohol fermentation for the optimization of ethanol production is evaluated, with fermentation time, final substrate concentration, cells and ethanol as performance indexes. A statistical planning for process optimization was employed by analyzing three independent variables: temperature, pH and Brix and the influence they have on dependent variables. Brix and pH had a significant effect on fermentation time with a 77% rate by analysis of variance. In the case of concentration of substrate and product, only Brix had a significant effect, with regression above 75 and 87%, respectively. Since the two models are valid at 95% confidence interval since Fcalculated is greater than Ftabulated, they may be employed to estimate fermentation time and the concentration of substrate and ethanol.

Resumo A destilação é o processo de separação mais amplamente utilizado nas indústrias, onde a separação de componentes de líquidos miscíveis é feita através da diferença de volatilização de cada um destes. Obtendo as variáveis que proporcionam maior rendimento e menor gasto energético, o objetivo do trabalho é otimizar a produção fixando valores de: tempo necessário para produção de bioetanol dentro da especificação de álcool hidratado; taxa de refluxo; e vazão volumétrica de produto de topo. Seguiu-se um planejamento experimental em que os dados foram configurados a partir da metodologia de Delineamento Composto Central Rotacional. Realizaram-se 17 processos de destilação no sistema descontínuo e em cada um destes houve a alteração das variáveis: razão de refluxo, pressão de vapor do refervedor e porcentagem de álcool na mistura a ser destilada, analisando a influência das variáveis de entrada do processo sobre as variáveis respostas: tempo de start-up, volume de bioetanol produzido, vazão (L.h-1) de bioetanol produzido e graduação alcoólica do produto. Durante os experimentos monitorou-se os perfis de temperatura do destilador, alambique, condensador e deflegmador, analisando como o comportamento desses podem afetar o processo de destilação.

Frente às demais emissões globais nos setores de emissões de CO2, apesar de apresentar um dos menores índices e parecer ser mínima a contribuição do setor aéreo no aquecimento global, estas são mais prejudiciais quando contrapostas às demais contribuições globais, uma vez que os poluentes lançados pelas aeronaves potencializam os efeitos do dióxido de carbono por conta das elevadas altitudes em que os aviões decolam (alta troposfera e baixa estratosfera), incidindo diretamente sobre as concentrações de gases do efeito estufa, intensificando o fenômeno do aquecimento global. Visando a evolução da demanda por energia e combustíveis, atrelados as necessidades de redução da emissão de poluentes, novas tecnologias vem sendo desenvolvidas para a aplicação e utilização das energias renováveis. Com as projeções de crescimento da aeronáutica, busca-se alternativas que reduzam a emissão de gases de efeito estufa e que minimizem a dependência dos preços do petróleo. Neste contexto,o objetivo deste trabalho é de reunir informações de como a bioquerosene se destaca entre os biocombustíveis como uma alternativa aos combustíveis fósseis, visto que pode ser obtida a partir de diversas fontes de matérias-primas que não concorrem com o setor alimentício e se adaptam a várias condições de clima e solo.
