  1. The noodle industry liquid waste is rich in ammonia and TSS and thus need to be processed before being flown to environment. A research aims to reduce the ammonia and TSS on liquid waste using biofilters has been conducted in March-April 2018.The noodle industry liquid waste (175 liters) wastreated using a batch system that was consisted of2 anaerob and 1 aerob tanks and Eichhrornia crassipes phytoremediation pond. The liquid waste was kept for 10 days in anaerob tank with gravel, sand and fibers media. Then the waste was kept for 7 days in aerob tanks with mangrove charcoal media.Finally the waste was kept for 15 days in a phytoremediation pondthat was completed with Eichhrornia crassipes. By the end of the experiment, the ammonia reduced from 9.123 mg/L to 0.415 mg/L (effectiveness 95.45%)and TSS reduced from 448 mg/L to 85 mg/L (effectiveness 81.02%). The treated waste was used for rearing Cyprinus carpio L. fingerling (4 - 7 mm TL) for 15 days and survival rate of the fish was 85%. Based on data obtained, the combination of anaerob-aerob biofilters and phytoremediationusing Eichhornia crassipes is effective to reduce the ammonia and TSS content in thenoodle industry liquid waste.
