Based on the principles of mass conservation, chemical equilibrium, and electron charge neutrality, a thermodynamic equilibrium system was established for nickel-cobalt-manganese sulfate leaching solution in recovery process spent lithium-ion batteries. By changing ion concentration system, calculating pH value, identifying complexes Cu2+, Fe3+, PO43−, Al3+, F− results were obtained used to dra...

Se evaluó la calidad del agua de seis manantiales que abastecen potable y riego agrícola a comunidad El Platanal, en Michoacán. realizaron dos campañas colecta, (estiaje precipitación pluvial). evaluaron parámetros fisicoquímicos, microbiológicos elementos traza. tipo predominante zona fue Ca2+-HCO3-. encontraron concentraciones Fe (0.8 mg/L) superiores los límites máximos permisibles por las n...

In order to improve the removal ability of nitrogen and phosphorus pollutants from sewage with low C/N ratio, this study prepared glucose polymer-based pyrite tailings core-shell structure through polymerizing on surface particles constructed a heterotrophic-sulfur autotrophic mixed-denitrification system. The experimental results show that compared ordinary tailings, modified by polymer can wa...

The microalgae–bacteria consortium is a promising and sustainable alternative for industrial wastewater treatment, since it may allow good removal of organic matter nutrients, as well the possibility producing products with added value from algae biomass. This research investigated best bacterial microalgae inoculation ratio system start-up evaluation removing (as chemical oxygen demand (COD)),...

Water masses are commonly identified according to their conservative parameters. However, there also studies that use non-conservative parameters, together with the ones, refine water identification. The aim of this study was analyze chemical properties in western tropical Atlantic Ocean (WTAO) inorganic nutrient concentration: nitrate-NO3–, phosphate-PO43–, and silicic acid-Si(OH)4, set a regi...

The objective of this paper is simultaneous of aerobic and anaerobic process for phosphorus removal from a dairy wastewater. The system consists of a granular sequencing batch reactor (SBR) working under alternating aerobic/anaerobic conditions. In order to analyze the process, four significant variables viz. MLSS, COD/N ratio, aeration time and cycling time and four dependent parameters as the...

Sulfate is an essential macroelement for all living organisms. However, sulfate can be limited in agricultural settings. Microorganisms change their gene expression to acclimate deficient conditions. Green microalga Chlamydomonas reinhardtii expresses and secretes extracellular arylsulfatase (ARS) under Our results show that C. ARS hydrolyze both monoester (5-bromo-4-chloro-3 indolyl sulfate; X...

Felszíni vizek minőségi és mennyiségi védelme az egyik legfontosabb feladat, ugyanis ökoszisztéma legmeghatározóbb természeti erőforrása a víz. A meghatározása során fizikai, kémiai, biológiai bakteriológiai vízminőségi paramétereket kell vizsgálni. Jelen kutatásunk fő célkitűzése, hogy vizsgáltok alapján meghatározzuk hogyan mely paraméterek befolyásolják leginkább a-klorofill tartalom horizon...
