The analysis of perspective collection and concentration technologies excess biomass in the wastewater surface water biological treatment with use aquatic organisms has been carried out. scheme a life cycle proposed. technological approaches for three types: plants macroalgae; developed root system microalgae A strategy concentrating high efficiency coagulation-flocculation gravitational thicke...

This review paper presents an overview of the available technologies used nowadays for the removal of arsenic species from water. Conventionally applied techniques to remove arsenic species include oxidation, coagulation-flocculation, and membrane techniques. Besides, progress has recently been made on the utility of various nanoparticles for the remediation of contaminated water. A critical an...

In order to improve the removal efficiencies of SS and Fe3+ in anaerobic digestion reject water for subsequent biological treatment process, on basis single factor test early stage, response surface method was used, structure formed floc analyzed by magnetic flocculation. The optimum amounts powder, polyaluminum chloride (PAC) polyacrylamide (PAM) were 40.51 mg/L, 31.31 mg/L 4.05 respectively. ...

Abstract Coagulation and flocculation provide a rather straightforward method towards water clarification. However, ongoing debates over worrying health issues linked to chemical coagulants have paved the way to develop plantbased natural coagulants. Natural coagulants are not only water clarifying agents, but they also have antimicrobial and heavy metal removal properties in some instances. Th...

In previous works, a low-cost predisinfection column that combined coagulation-flocculation and GAC filtration was proposed for combination with electrodisinfection in the successful treatment of highly faecal polluted surface water. this work, is adapted pore water by transforming coagulation chamber into chemical reactor lime replacing filter ion exchange resins. This system can soften water,...

Following biological treatment, wastewater continues to have endotoxic active materials. However, because there is a trend of potable reuse and because endotoxic active materials potentially have harmful effects on human health, their removal from water is crucial. Lipopolysaccharide endotoxin has hydrophobic groups, and their removal using a coagulation-flocculation alternative is believed to ...
