Chapter 22.9, Problem 1MQ
Summary Introduction
Drinking water should be free of any impurities, organic and inorganic matter, odor and microorganisms. Treatment steps which are followed in drinking water treatment plant from inlet to final distribution point are sedimentation, coagulation, filtration, and disinfection.
