Treatment of waste water by coagulation and flocculation
The present study deals with the determination of physical and chemical parameters in the treatment process of waste water by flocculation and coagulation processes using natural coagulants and assessing their feasibility for water treatment by comparing the performance with each other and with a synthetic coagulant.
Consequently, effective treatment of wastewater requires effective solid-liquid separation. Furthermore, coagulation, which is considered here to involve the chemical destabilization of particulates and the physical transport of these destabilized particles to form larger aggregates, is an essential component of all wastewater treatment systems.
Coagulation for Wastewater Treatment : A Review
water, nature of the treatment after coagulation and degree of purity of reagents are determinants in choice of coagulants. Sostar-Turk et.al. carried out investigation on coagulation and membrane filtration processes for laundry wastewater treatment [24]. They carried out wastewater treatment with conventional method
