“ Wastewater Treatment by Natural Coagulant”

1)     Natural Coagulant does not have any effect on human health 2)     Chemical coagulant Sludge   produced    is   voluminous   and   non-biodegradable   after   treatment   and   therefore poses disposal problems leading to increase cost of treatment.  3)     Chemical coagulant cost is increasing day by day. 4)     Preparation of chemical coagulant required substitute chemical. Natural coagulant is easily manufactured. 5)     All coagulants are easily available. 6)     At the time of application of dose daily fresh solution should prepared. 7)     Among theTwo natural coagulants used in the study, maximum turbidity reduction is found to be 82.02%with Moringa oleifera.
