Efektifitas Penggunaan Biofilter Dengan Proses Anaerob, Aerob Dan Kiambang (Salvinia Molesta) Untuk Menurunkan Kadar Mbas (Methylen Blue Active Substance) Dan Fosfat Pada Limbah Cair Laundry
The laundry waste is rich in MBAS and phosphate and its need to be processed before being flown to environment. This study aims to determine the ability of a batch biofilter system in reducing the phosphate and MBAS content. This study has been conducted in January-March 2018. The laundry liquid waste (175 liters) was kept in 2 anaerobik tanks that was completed with gravel, sand and palm fibers media for ten days.Then the waste was flown to aerobik tanks (coconut shell charcoal media) for seven days. Finally the waste was treated in a phytoremediation pond that was completed with Salvinia molesta for fifteen days. By the end of the experiment, the phosphate reduced from 11.6-0.8 mg/L (the effectiveness was 92.67%) and the MBAS reduced from 10.5-1.3 mg/L (the effectiveness was 87.16%). Other water quality parameters such as pH was normal and temperature and DO were improved. The treated waste was then used for rearing Cyprinus carpio (5-7 cm TL) for 10 days. The survival rate of the fish was 89%. Based on data obtained, it can be concluded that the combination of biofiters and phytoremediation system using Salvinia molesta is effective to reduce the phosphate and MBAS content in the laundry liquid waste.
