The principle of membrane micro-filtration technology was employed to filter fresh palm oil mill effluent (POME). Dead-end configured filtration system was used to recover substantial amounts of the suspended solids and oil & grease with appreciable removal efficiency for COD, TSS, TS and O&G. The dried sludge (DSO) was used as a feed major ingredient together with defatted fishmeal to formulate a diet. Three different diets were tested on Nile tilapia: O. niloticus fingerlings comprising of DSO mixed with defatted fishmeal, crude palm oil (CPO) and defatted fishmeal and a third group of fingerlings fcd with Fish oil (FO) mixed with defatted fishmeal as a control. The growth of all fingerlings was monitored every 2 weeks for a period of 8 weeks. The result showed that there is significant growth performance in fish fed with DSO indicating that it can be used as a fish feed ingredient to supply some proteins and lipids.
