Waste water treatment is gaining much importance in recent years with the intension of reusing it.
For the treatment of wastewater large amount of materials are to be supplemented. Nutrient rich
wastewater instead of discharging into environment is supplemented for the growth of algae in the
wastewater treatment. Thus nutrients can be reused and wastewater can be treated and thus reducing
the negative impacts. As the algae takes up N and P, the wastewater can be treated with algae. This
paper explains wastewater treatment by macroalgal species.
