Susan, V., interesting work by Li and Chu (2003) shows that membrane Biorector treat a polluted water to be better in term of quality than local tap water

Well Adamu and Susan it all depends on the quality and components of the water we have as feed. Still the polluted water treated by Li and Chu method will question of consumption as we got to see the toxicity of the polluted water before treatment and after treatment. This is very complex to rely on such treatment. As per the question of Susan, well when it is potable water it is pure, why do we need bio reactor treatment? for what? What we are going to treat is the question.
