Waste-Water treatment in a passively aerated vertical bed

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 of treating industrial waste water by employing microalage in a passively aerated vertical bed. The growth kinetics of micro-algal species under various conditions are investigated and the passively aerated vertical bed seems to be an very attractive option for treating waste-water with a recourse to generating non-renewable energy.
