Tóm tắt

The present investigation was attempted to reduce the toxic pollutants from the different mixtures of water samples (sewage, sea and well) using the freshwater alga, Chlorella vulgaris and the marine alga Chlorella salina. The results revealed that both algae species were highly efficient and having a potential to reduce pH, total dissolved solids (TDS), biological oxygen demand (BOD), chemical oxygen demand (COD), nitrate, ammonia, phosphate, sulphate, calcium, magnesium, sodium, potassium, heavy metals (Zn, Cu, Mn, Ni, Co, Fe and Cr) and the number of total Coli-form bacteria after 10 days of treatment compared to the untreated water samples. The removal efficiency of heavy metals was 13.61–100 %. In general, C. vulgaris shows higher removal efficiency in most of parameters than C. salina.
