Bioremedation of Effluent Wastewater Treatment Plant Bojongsoang Bandung Indonesia Using Concorsium Aquatic Plants and Animals

Abstract

Volume of domestic or household waste increased by 5 millions meter cubic per year, with an increase in the average content of up to 50%. Components in the domestic waste water can lead to imbalances disrupt aquatic ecosystems and human health, such as the presence of Escherichia coli, and the possible presence of hazardous substances such as elemental N, P, As, Cr, and Se which can lead to poisoning of fish, birds and mammals. Bioremediation is the application of biotechnology domestic wastewater utilizing living things include plants and animals as agents of degrading pollutants. This research uses a consortium of Eichhornia crassipes (F1), Salvinia molesta (F2), Ceratophyllum demersum (F3), as well as aquatic animals Anodonta woodiana (Z1) and Limnodrilus hoffmeisteri (Z2) because it has a high potential to degrade or absorbing compounds in domestic wastewater. Experiments using Randomized Complete Design (RCD), 12 treatments and 3 replicates. Observed levels of efficiency (Ef) and the rate of degradation (Ld) or rate of gradation (Lg). Observations of turbidity, color and froth domestic wastewater done for 14 days. Testing or measurement of physical and chemical properties at day-0, the 1st, 3rd and 5th. The results revealed a consortium F1F2F3Z1Z2 on turbidity Ef 86%─Ld 14 mg/L/day, BOD Ef 70%─Ld 19 mg/L/day, COD Ef 67%─Ld 31 mg/L/day and clear the fastest on day 4; consortium F2F3Z2 on ammonia Ef 95%─Ld 0.62 mg/L/day, nitric Ef 91%─Ld 0.11 mg/L/day and the lowest gradation TDSEf 0%─Ld 0 mg/L/day, F1F2F3Z1 consortium gradation lowest TSS Ef 50%─Lg 1 mg/L/day, and a consortium F1F3Z1 Ef 77%─Ld 1.30 mg/L/day in nitrate.
