How AIRUS biogas booster roots blower do in Malaysia and Indonesia palm oil mill effluent (POME) treatment?
Biogas Trapping
Phase 1. Anaerobic digestion at mesophilic temperature of 36°C was able to generate biogas consisting of an average of 68% CH4, 28% CO2 and 850 ppm H2S.
Based on 10 hr operation, it produced biogas at a rate of 52.7 m3 hr-1 with a total production of 21-25 m3 biogas per m3 POME (based on chemical oxy-gen demand, COD removal). A desulphurisation system installed using chemical treatment showed ~70% removal of H2S.
Phase 2. The one year performance was based on 24 hr monitoring for 12 months. The digester tanks were able to produce an average of 28 m3 biogas per m3 of POME (based on COD removal). The average compositions of biogas were 57% CH4, 42% CO2 and 418 ppm H2S.
