As many research works are going on in the field of wastewater treatment, a newly
developed wastewater treatment by algae is gaining much importance. The algae
selected for the study was Oedogonium and Chara sp. Various parameters like Biological oxygen
demand (BOD), Chemical oxygen demand (COD), Ammonia Nitrogen and Phosphate were
observed after the treatment. Percentage reduction rate of 59.61(BOD), 53.97 (COD) were
observed. This is an environmentally safe alternative for treating wastewater
