Using Microalga Scenedesmus quadricauda for the Improvement of Municipal Wastewater Quality

Microalgae culture is an interesting step in wastewater treatment since it provides a tertiary biotreatment while also producing potentially valuable biomass that may be used for variety of applications. cultures, with their ability to utilize inorganic nitrogen and phosphate growth, provide elegant solution quaternary treatments. Scenedesmus quadricauda was employed three different doses, 2g/l, 1g/l, 0.2g/l, investigate the impacts microalgae wastewater. Standard procedures were measure samples physicochemical parameters such as pH, EC, PO4, NO3, NO2, NH4 BOD5 every third day 21 days. Results showed higher dose 2g.l-1 most effective removing highest rate nutrients. It confirmed by significant differences (p≤0.05) between all doses. Ammonium pass had removal percentage 97%, followed NO3 95.7%, range 90.3 93.5 %. Decreases nutrients accompanied rise chlorophyll content, greatest 1.52 mg. l-1 on 17th experiment. The purpose this paper overview methods use bioremediate organic contaminants aquatic ecosystems.
