Comparative study of naturally available coagulants

Abstract

In this study we evaluate the “comparative study of naturally available coagulants” by performance coagulation-flocculation for removing turbidity as well as hardness from various waste water sample. The jar test apparatus consists of six jars containing different dosages of natural coagulants such as Moringa olifera, Tamarind, Nirmali etc. The procedure of coagulation-flocculation is carried out simultaneously. Later an optimum dosage is obtained for each coagulants. Comparative study of naturally available coagulants is carried out considering factors such as amount of removal of turbidity and hardness from waste sample, amount of sludge generated from samples, funds required for the treatment , environment affection point of view etc.
