PENGOLAHAN LIMBAH POME (PALM OIL MILL EFFLUENT) DENGAN MENGGUNAKAN MIKROALGA

Abstract

Along with increased produktivity of palm it will be followed increase in wastegenerated. Each palm mill wasted liquid waste known as palm oil mill effluent (POME). POME contains BOD and COD are very high, so it can inhibit the growth of microalgae in the POME. Therefore, comprehensive research is needed to find out a pretreatment step in lowering the content of BOD and COD in POME before being used as a medium for the growth and development of microalgae. Research POME waste water as a medium of growth and development of microalgae is specifically aimed at studying the treatment process of POME using wild microalgae. The procedure of mixing experiments conducted POME and microalgae erlemeyer fitinto the specified ratio. Research shows that pond IV POME waste can be used as growth wild mikrolga, so it can reduce the levels of BOD and COD of POME waste. Modifiers of variable are applied volume of POME ratio of the volume of microalgae and the amount of nutrients provided. Growth of microalgae with a ratio of 1:4 resulting in a reduction of BOD and COD at both the 61.66 ppm and 173.33 ppm from 110.6 ppm and 496.67 ppm. On the effect of nutrient giving C 120 ppm resulted in lower BOD and COD at the 65.33 ppm and 186.67 ppm, where as the effect giving nutrient N 40 resulted lower and COD reached 55.41 ppm and 158.33 ppm.
