SINOPSIS

Spirulina can be cultivated in wastewater to improve water quality. Batch studies were conducted for the treatment of anaerobically digested wastewater (ADW) by using Spirulina sp. This study examines the possibility of using Spirulina sp. to remove COD, BOD, heavy metals, and bacteria from wastewater. The results showed that the growth of Spirulina in ADW was poor, but can be enhanced by the addition of NaHC03 up to 4% to 5% as a carbon source, which gives maximum productivity at 1.4 mg/L. It also showed the removal of COD up to 80%, BOD up to 95%, and cations such as potassium 98%, calcium 96%, magnesium 95%, and sodium 90%. Anions such as chloride 51%, nitrate 52%, phosphate 76% and sulphate up to 60% were removed from effluent heavy metals, e.g., Ni was removed up to 57% and Pb up to 97% the total bacterial count was reduced up to 75% in the growth period of eight days.
