Constructed wetland systems (CWs) are technologies based on natural processes for pollutant removal and have been more and more accepted in the treatment of domestic and industrial wastewater. This study selected and reviewed articles published in the last six years involving the use of different CW conceptions and their association with other technologies to treat different effluents and evaluated the quality of the effluents for reuse. From a total of 81 articles reviewed, 41 presented quantitative data on the quality of the treated effluent in relation to the requirements of the reuse regulations in different countries of the world. CWs can be used to treat gray water and runoff water, as well as domestic and industrial effluents with the purpose of reusing them. While studies on the removal of new chemical and biological substances have increased, challenges are associated with the optimization of CWs to improve the removal of pathogens and new contaminants that have appeared more recently. The potential for the improved removal of those pollutants lies in the association of CWs with conventional and advanced technologies in new configurations. We concluded that studies related to the reuse of effluents using CWs are in constant evolution, with experiments at different scales. The perspectives are promising since CWs are an economic, environmentally friendly, and efficient technology to help in the mitigation of water scarcity problems imposed by climate changes.

RESUMO O processo de biorreator com membranas tem se consolidado nos últimos anos como uma alternativa aos métodos tradicionais para o tratamento de efluentes da indústria de produção de papel. Recentemente, a introdução de material suporte nesses reatores tem contribuído para a melhoria de seu desempenho, tendo em vista a maior atividade biológica que se verifica em decorrência do desenvolvimento de biofilme. Assim, a presença da biomassa aderida confere uma capacidade adicional ao biorreator com membranas em suportar choques de cargas, bem como pode contribuir para a biodegradação de compostos potencialmente tóxicos e recalcitrantes como derivados da lignina. Desse modo, o presente trabalho teve como objetivo avaliar o desempenho de um biorreator à membrana de leito móvel operado em batelada sequencial e aplicado ao tratamento de efluente real de baixa carga oriundo da produção de papel. O reator foi avaliado quanto ao seu desempenho na remoção de demanda química de oxigênio solúvel, fenol total, cor verdadeira, compostos aromáticos (UV254nm) e lignínicos (UV280nm). Paralelamente, o reator foi avaliado quanto ao processo de colmatação das membranas, por meio do monitoramento da pressão transmembrana, da concentração de substâncias poliméricas extracelulares e produtos microbianos solúveis). Nas condições testadas, o biorreator à membrana de leito móvel operado em batelada sequencial atingiu eficiência média de remoção de 89% para demanda química de oxigênio solúvel, 39% para UV254nm, 38% para UV280nm, 57% para cor verdadeira e 73% para fenóis totais. Em relação à colmatação das membranas, as variáveis UV254nm, UV280nm e fenóis totais correlacionaram-se diretamente com o aumento da pressão transmembrana (PTM).

Abstract The humic compost obtained from the treatment of tobacco from smuggled cigarettes (SCT) and industrial sewage sludge (ISS) was evaluated as adsorbent for Cd (II) in aqueous solution, for possible decontamination of water resources. Optimum conditions were found at pH 5 and a 3 g/L adsorbent concentration, which presented 92% Cd (II) removal and maximum adsorption capacity of 28.546 mg/g. The pseudo-second-order kinetic model presented the best fit, pointing 120 min as the time needed to attain a steady state. FTIR and EDX results suggest the formation of coordinated Cd (II) bonds by functional groups between the compost and the solution. The results obtained in real samples showed that, even under different environmental conditions, the Cd (II) adsorption varied between 80.05 and 91.61%. The results indicated that the compost evaluated can be used for remediation of Cd (II)-contaminated water resources.

The study of cigarette authenticity in Brazil is important due to increasing consumption of contraband cigarettes. Nicotine concentration is an important parameter reflecting the quality of tobacco used in the production of these cigarettes. Simple methods for this determination, which produce reduced waste, are environmentally and industrially important. The nicotine concentration of smuggled cigarette tobacco was determined by the QuEChERS method, requiring some modifications, such as decreasing the volume of the extractor solvent, changes in pH, and removal of the sample hydration step. Quantification was performed by gas chromatography using a flame ionization detector. The Doehlert matrix design was used to optimize the method. The extraction recoveries ranged from 97.5% to 99.6%, with relative standard deviation (RSD) ≤ 2.5% and limits of detection and quantification of 0.6 mg L-1 and 2.5 mg L-1, respectively. The method was sensitive and accurate for the detection and quantification of nicotine. The nicotine concentration in contraband cigarettes was found to be lower than that observed in legal cigarettes. The method was successfully applied to real samples of smuggled and legal cigarettes, providing a robust method for routine analysis and proving the need for more studies on quality control of smuggled cigarettes in Brazil.

The objective of this study is to propose a new post-treatment of effluents from Upflow Anaerobic Sludge Blanket (UASB) using rapid filtration, aiming at the production of water for potable reuse. The final quality of the effluent produced by the treatment using gravel, sand, clinoptilolite and activated carbon associated with disinfection was evaluated by physical chemical analysis, heavy metals and persistent organic contaminants. Experiments were carried out in jar test, filter operation time, evaluation of the efficiency using peracetic acid and free chlorine as disinfectant and all results were statistically analysed. The best conditions were those using 20 mg/L of ferric chloride and natural pH of the effluent (≈ 7.0), which resulted in less reagent consumption. The use of intermediate fund discharges made it possible to obtain approximately 91% of recovered water efficiency. The effluent treated under these conditions showed DOC <2.0 mg/L, COD <1.0 mg/L, BOD <1.0 mg/L, turbidity <1.0 NTU, TSS <1.0 mg/L, ammonia <0.1 mg/L, total phosphorus <0.1 mg/L and surfactants <0.1 mg/L. The disinfection process with free chlorine and PAA allowed the total inactivation of faecal coliforms and total coliforms. The treatment using rapid filtration with disinfection by chlorine reached the appropriate level for urban, environmental, industrial and indirect potable water reuse.

In this study, the effect of the bioaccumulation of metals on Oreochromis niloticus tissues was evaluated. Significant Co, Mn and Ni concentrations were found in the lake water near the fertilizer industries. In the sediment was identified the presence of Cd (4.612 ± 0.930 mg kg -1 ), Ni (46.847 ± 3.801 mg kg -1 ) and Zn (865.534± 89.437) mg kg -1 ) in concentrations above the probable effect level (PEL). For Cu (141.963 ± 5.148 mg kg -1 ) and Pb (53.362 ± 6.621 mg kg -1 ) concentrations between the threshold effect (TEL) or probable effect (PEL) levels. Regarding Oreochromis niloticus tissues, the concentration of metals in the liver was higher than found in muscle. The biomarkers indicated that the hepatic cells of Oreochromis niloticus are under oxidative stress, explained by the higher levels of reduced glutathione (GSH), lipid peroxidation (LPO) and protein carbonylation (PCO) when compared to control fish tissues. The set of biomarkers presented in this study contribute to define the effects of the bioaccumulation of metals in Oreochromis niloticus tissues. DOI: http://dx.doi.org/10.17807/orbital.v11i7.1366

Organic waste is among the solid waste produced worldwide. When such residue is improperly accumulated and disposed of, it generates environmental impacts, polluting soils, rivers and the air. The objective of the present study was to investigate the use of a 2000 liter capacity reactor for composting domestic organic waste, wood chips and smuggled cigarette tobacco. Physicochemical analyzes (pH, temperature, humidity and C / N ratio), biological (germination test and pathogens) and spectroscopic (UV-Vis and FTIR) analyzes were performed to monitor the process. In addition, the influence of two different C/N ratios was investigated. C/N ratio analyses and phytotoxicity tests showed that the compound reached maturity over a period of 120 days. Spectroscopic analyzes of UV-Vis and FTIR showed efficiency, indicating the degradation of compounds of simpler structure and the formation of humified compounds. The microbiological and heavy metal analyses of the final compounds revealed that the results are in accordance with the legislation. The different C/N ratios showed very close results, not affecting the composting process. Thus, the proposed treatment of domestic organic waste and smuggled cigarette tobacco in facultative reactors of 2000 liters was seen to be efficient and produced mature compound in the different C/N ratios studied.
