Biotreatment of Industrial Effluent Using Indigenously Isolated Algae

摘要

Algae can be used for tertiary treatment of wastewater due to its capability to assimilate nutrients. The below mentioned study addresses the adaptation of algae strain of indigenous origin, isolated from the premises/disposal area of oil blending plant, for the reduction of chemical oxygen demand (COD) and generation of biomass . The algae utilizes the pollutants for biomass generation thus reducing organic pollutants from the effluent water. The highest biomass production and COD removal (98%) occurred in media supplemented with nitrate as nitrogen source. Treated water obtained is efficient enough to be used as ferti- irrigation water as demonstrated in the seed germination test. The below mentioned paper exhibit the possibility of using microalgae for COD removal and biomass production.
