background and aims: nowadays heavy metals are the environmental priority pollutants and are becoming as the most serious environmental problems. in recent years removing those from diverse industrial effluents and metal cleaning have been studied. the aim of the present study was to investigate the different methods for cooper removal of cooper ions from industrial wastewater. methods: this st...

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 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,...

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...
