Deacidification of palm oil mill effluent using anion exchange resin

This paper described the method to deacidify Palm oil mill effluent (POME) by substituting FFA contents to anion from exchange resins (Dowex Marathon A and Lewatit MP500). The deacidification was conducted in a fixed bed column reactor using two different effluents, collected from factory fat pit and cooling pond. Furthermore, the acid values were evaluated to calculate the quantity of FFA content. After deacidification, the acid values of POME from the two sources were lower than 1 mgKOH/g oil and with a brighter color.
