Abstract


Coagulation is the process of removal of very fine particles by forming bigger flocs in the water. But this process is not much efficient in waste water treatment as in the treatment of drinking water. This is because of adding chemical coagulant for the treatment of waste water. Use of chemicals in treatment of dyeing waste water causes formation of non-biodegradable sludge. To avoid this we made an attempt in the treatment of water by using plant based natural coagulant. Here we tried garlic, as natural coagulant for the treatment. The extract of garlic was obtained and it was used in this process. The result was found in a greater efficiency in the removal of hazardous chemical composition present in the dyeing waste water. From the result, it was obtained that 96% of COD and 93% of BOD has been achieved. Also the iron and chromium have been removed 100%.
