While most stud­ies con­cen­trate on organic removal from palm oil mill efflu­ent (POME), the result­ing nutri­ent recov­ery and sub­se­quent removal from the waste­water is infre­quently described. Although spo­radic research has been per­formed to inves­ti­gate nutri­ent removal effi­ciency of a sin­gle tech­nol­ogy, the effi­cacy after com­bined with other tech­nolo­gies, which usu­ally hap­pened in indus­trial efflu­ent treat­ment sys­tems (IETS) has not been thor­oughly checked. Hence, this study assessed the effec­tive­ness of four IETS hav­ing dif­fer­ent tech­nol­ogy com­bi­na­tion in nutri­ent removal. Nutri­ents such as total nitro­gen (TN), ammo­ni­a­cal nitro­gen (AN) and total phos­pho­rus (TP) from POME of these IETS were analysed. Of the four IETS inves­ti­gated, the com­bined pond­ing sys­tem, anaer­o­bic digesters and extended aer­a­tion cou­pled with fixed pack­ing in acti­vated sludge aer­a­tion tank showed the high­est nutri­ent treat­ment effi­ciency (92.5% TN, 94.5% AN and 93.5% TP). Mov­ing for­ward, POME man­age­ment should gear towards sus­tain­able recov­ery of essen­tial nutri­ents through oper­a­tive technologies.
