Waste-water treatment is an important issue in the present day because of the strong nexus between water and fuel.It becomes more complicated with the depleting fossil fuel resource.Hence the waste-water treatment technology need to made more fuel efficient and attractive to the industries.Treating industrial waste-water by employing microalage seems to be a feasible option more so when it exhibits the potential of generating energy.energy. Micro-algae based waste-water treatment can be accomplished in a photobioreactor or/and passively aerated vertical bed. This work explores the feasibility...
