The removal of phosphate from wastewaters prior to discharge into natural water is an essential measure to prevent eutrophication in receiving waters. Phosphate removal through adsorbents, such as activated alumina, powdered aluminum oxide, activate red mud, flyash, blast furnace slag and other materials, is commonly and successfully practiced. The wasted sludge from seafood processing factory prepared on a laboratory scale has been used to evaluate its performance for phosphate removal. The material has been shown to be a good alternative adsorbent. As much as 90% phosphate removal by the prepared sludge is possible in about 20hrs under the test conditions. Phosphate removal is seen to increase with decreasing adsorbent particle size, increasing relative concentration of phosphate to sludge and increasing adsorbent dose. The removal efficiency is not precipitation dependent in these experimental circumstances.
