Mit School Of Engineering How Can Harmful Substances

dec 11, 2012 the most basic and inexpensive ways to purify water involve adding substances that allow the harmful bits to be easily removed. when chlorine gas or tablets are added to waste water, the chlorination kills the bacteria, and simple charcoal filters can remove some of the suspended solids, which might often be enough, explains bajpayee.
