Raw palm oil mill effluent POME is composed of carbohydrates 29.55 ashes 14.88 protein nitrogenous substances 26.39 lipids and vitamins. Since nutrient content in POME is high this waste product has potential to be used as microbial growth medium. The dark-brown colour of raw POME may inhibit the microbial growth since this colour is produced by phenolic compounds.

Abstract

Raw palm oil mill effluent POME is composed of carbohydrates 29.55 ashes 14.88 protein nitrogenous substances 26.39 lipids and vitamins. Since nutrient content in POME is high this waste product has potential to be used as microbial growth medium. The dark-brown colour of raw POME may inhibit the microbial growth since this colour is produced by phenolic compounds. The aim of tbis study was to optimise the decolourisation process of raw POME with its nutrient content still remaining. In the first process. POME was filtered using muslin cloth prior to optimization of decolourisation using chitosan. The results showed that addition of 3 g/L chitosan removed 57 colour reduced 24.4 total phenol and 727 mg/L of total nitrogen still remained. The optimum decolourisation of POME was obtained at pH 3 in which at this acidic condition. the colour and total phenol was removed by 58.49 and 42.7 respectively with 683.3 mg/L of total nitrogen still remaining.
