Abstract

It deals with bio-material based coagulant and determination of its residual turbidity removal. The objective of this thesis is to identify Planet-friendly materials for the water treatment, to remove the suspended impurities, to find optimum coagulant dosages and to check the water quality standards as per World Health Organisation (WHO). The bio-materials are identified by studying the Journal papers collected from various reliable sources. The materials are selected based on the following criteria: i. The turbidity removal should be greater than 70% ii. Easily available and economical. The Turbid water is prepared using Red soil available locally. The pH of water is determined initially for the purpose of deciding effective turbidity removal. So far, the bio-materials chosen is Acacia catechu bark powder. The extracts of the chosen material is prepared using distilled water. The extracts are added to the turbid water samples at various dosages, various pH, various levels of turbidity, various volume of extract and various soaking time. Three different sizes of powdered material are used. Finally, using optimum values, water collected from lakes in and around Coimbatore were tested. For the above mentioned purpose, Jar Testing Apparatus and Nephelo Turbidity Meter are to be used.
