Abstract

Phytoremediation is a novel technique that uses algae to clean up polluted water and soil. It takes advantage of the alga's natural ability to take up, accumulate and degrade the constituents that are present in their growth environment. Algae based waste water treatment systems offer more simple and economical technology as compared to the other environmental protection systems. Photosynthesis can be effectively exploited to generate oxygen from waste water remediation by algae. The choice of algae to be used in wastewater treatment is determined by their robustness against wastewater and by their efficiency to grow in and to take up nutrients from wastewater. By using Synechocystis salina almost 60% Cr, 66% Fe, 70% Ni, 77% Hg, 65% Ca²⁺, 63% Mg²⁺ and 78% of total hardness was reduced in 15 days of treatment.
