Decrease of Organic Pollutans Palm Oil Industry Using By Biosand Filter and Mangrove Charcoal for Fish Aquacultur Media Life

Abstract

The research was conducted from November 2012 until Januariy 2013 at palm oil industry of PT. PN V Sei. Galuh Tapung subdistrict, Kampar Regency. It’s was aims to understand the effectiveness of biosand filter and mangrove charcoal in reducing organic pollutans content in liquid waste of palm oil mill for live media of fish aquacultur. Sampling of COD and BOD5 were taken in three point with interval every 2nd week during 2 months for 5 times and Analyzed in Laboratory of the Departement of public works and microbiology then compare with Kep-122 /MENLH/2004 attachments B. Liquid waste of palm oil mill Processing by use of four reactor units biosand filter and two reactor mangroves charcoal have can reducing organic pollutans with decreased BOD rate of 261,3 mg/l becomes 51. 92 mg/l with effectivenesses 80,13 %. While that of COD from 952,8 mg/l to183.6 m/l with effectivenesses 80,73 mg/l. And percentage of survival rate for common carp 40%, tillapia 60%, and patin 77%. It’s compliance with quality standard and as good as for patin life media.
