Efektifitas Biofiltrasi Dengan Media Arang Tempurung Kelapa Dan Batu Apung Terhadap Penurunan Kadar COD, Nitrat Dan Amoniak Dalam Air Limbah Domestik

Abstract

This experimental study aims to determine the most optimal biofiltration media composition for domestic wastewater treatment using 4 upflow biofilter reactors with a combining pumice and coconut shell charcoal as an media filter. ,The combination ratio of media filter is UAF 1 = 1: 0, UAF 2 = 2: 1, UAF 3 = 1: 2, and UAF 4 = 1 : 1 with an overall filter media thickness of 60 cm. Sampling time is done every 2 days for 16 day were taken at the four experimental reactors to be tested for each parameter of pH, COD, nitrate and ammonia. The method of analysis carried out after obtaining data from testing in the laboratory, that is descriptively related to variations in filter media, and the residence time of wastewater in the reactor. The results showed that the reactor with the best processing in normalizing pH was UAF 1. While the best filter media composition in COD and nitrate removal was UAF 3 reactor with 77.78% and 87.17% removal results. Ammonia removal occurred throughout the experimental reactor with a result
