Abstract

Anaerobic digestion (AD) process is a widely applied method for biogas production and wastewater treatment of palm oil mill effluent (POME). AD foaming is one of the major problems that occasionally occur in many biogas plants, since it affects negatively the overall digestion process. The effect of individual substrates and intermediate compounds on foaming potential in POME anaerobic digestion systems was investigated. Effect of interaction of each compound was investigated by fractional factorial design and tested,for foaming potential in both pure water, POME and POME under AD. The results showed increased concentration of substrate and intermediate compounds in waster could create more foaming tendency but not effect on foaming stability. Each compound in a complex mixture showed that BSA, Na⁺, lactic acid and cellulose has foaming tendency in water while no created foaming stability. Na-oleate and Na²⁺ showed strong foaming tendency while butyric acid, acetic acid, Mg²⁺, SDS, peptone, gelatine and BSA showed more effect on foaming stability in POME. In AD systems found that highest methane production about 11.15-15.95 L-CH₄/L-POME and yield about 179.05-256.08 mL- CH₄/g-VS added. BSA, gelatine, oil palm and lactic acid has highest foaming stability in AD systems.
