Penyisihan Polutan Pada Palm Oil Mill Efluent (Pome) Menggunakan Konsorsium Mikroalga-Bakteri Dengan Variasi Konsentrasi Suspensi Mikroalga Pada Sistem High Rate Algae Reactor (Hrar)
ABSTRACT
Palm oil mills in addition to producing crude palm oil also produces by-products in the form of Palm Oil Mill Effluent (POME). POME contains high amounts of organic ingredients and pollutants. One method that can be applied to process POME is High Rate Algae Reactor (HRAR) System. The HRAR system utilizes consortium of indigenous microalgae-bacterial that has better performance in removing pollutants in POME and increasing the growth of microorganisms. This research aim by determined the effect of microalgae suspension concentration in the HRAR system towards the removal efficiency of COD and total nitrogen. The research was conducted in batch in the HRAR system that equipped with a paddle wheel, by variations in the concentration of microalgae suspension was 0; 10; 15; 20; and 25%. The research was carried out for 7 days and used the sun as a source of light. Based on the research results, 25% of microalgae suspension concentration has the highest microalgae cell density, was 6,34 x 106 cells / mL and showed the best removal efficiency of COD and total nitrogen, was 78.79% and 80.37%.
Keywords: Microalgae-Bacterial Consortium, Palm Oil Mill Effluent (POME), Pollutant, High Rate Algae Reactor (HRAR).
