Effect of Operating Variables for Phosphate Removal with Cuttlefish Processing Sludge

오징어가공 슬러지를 이용한 인산염인 제거 공정에 미치는 영향인자

The removal effect of phosphate by sludge from wastewaters prior to discharge into natural waters is an essential measure to prevent eutrophication in receiving waters. There is need for developing low cost, easily and abundantly available, efficient adsorbents for the removal of phosphorus (P as orthophosphate) during the tertiary treatment of wastewaters. The adsorbent carbon which is prepared with fisheries wastes on a laboratory scale has been used to evaluate its performance for phosphate adsorption. Phosphate removal increase with increasing adsorbent dose and temperature, but shows no changes at an adsorbent dose over 8 g/l.
