CHEMICAL TREATMENT PROCESS OF SEWAGE WATER
Publication number: 20170190600
Abstract: A process for the treatment of sewage water to contaminant free water is done by two steps of basification or acidification followed by neutralization. Basification occurs by adding basic chemicals to sewage water up to 12 PH followed by adding acidic chemicals up to 7 PH for neutralization. Similarly acidification occurs by adding acidic chemicals up to 4 PH followed by adding basic chemicals up to 7 PH. The sludge formed during basification and acidification is separated from two steps of treated sewage water. For better results basification is extended up to acidification PH followed by adding of acidic chemicals up to 7 PH, similarly acidification is extended up to basification followed by adding of basic chemicals up to 7 PH. Gases generated in the whole process can be absorbed by ferrous chloride and/or calcium chloride added to the acidification and basification reactions.
