The optimum condition to enhance degradation of organic matter in palm oil mill effluent (pome) using bio media bioreactor

Bio media bioreactor is a combination of the concept of bio filter process and bioreactor. There are a number of small package treatment plants with different brand names currently available in the market in which different shaped plastic materials are packed as filter media and are mainly used for treating small amount of wastewater. Bio media or bio filter is effective in removing the organic substances that can cause the microbial growth after the POME treatment. Formulation of 1:9 Pseudomonas putida to POME, the bacteria was injected into the bioreactor. The optimum conditions for this treatment are where the aeration time (1L/min), rotational speed (180rpm), 100 percent supply of oxygen, and temperature of surrounding is at 37 ˚C. With those conditions, the results was obtained. The pH is between 7 to 9, the removal efficiency of chemical oxygen demand (COD) (46.73%), biochemical oxygen demand (BOD) (99.03%) and total suspended solids (TSS) (71.88%) of the treated POME. Therefore the POME should be treated by using biological treatment which is bio media bioreacto
