Treatment Of Anaerobic palm oil mill effluent using several Polymers

Palm oil mills industry generates large amounts of highly polluting effiuent and usual1y it is being treated in anaerobic ponding/tank system to reduce the pollutants. However, the colour from anaerobic effiuent (AnPOME) become dark brownish. Beside lignin and tannin, anaerobic digestion product lik...
