Abstract
Nitrification Is an important facet of water recycling fish culture system, because the toxic cation ammonia is converted to the innocuous anion nitrate. This study was attempted to find the optimal design factor of submerged filter for ammonia removal in water recycling fish culture system. The experimental system was designed submerged filter with corrugated skylight plate, and operated in the fish farm, National Fisheries University of Pusan. When the influent ammonia concentration was about 10mg/l (9.43-13.66mg/l) nitrification rates were tested for the removal of ammonia over a four stage of the hydraulic loadings. The submerged filter removed 76.24, 62.88, 39.09 and
어류를 고밀도 순환여과식으로 양식하는 담수양어장에서 암모니아를 제거하기 위하여 고정 생물막 질산화 반응으로 처리하는 잠수여상 장치를 사용할 때 최대의 양식밀도와 최적의 운전조건을 파악 할 목적으로 수리학적 부하율에 따른 암모니아 제거효율 실험을 실시한 결과는 다음과 같다. 유입수의 암모니아 농도가 약 10mg/l(9.43-13.66mg/l)일 때 암모니아 제거율은 각각의 수리학적 부하가 0.028, 0.037, 0.056 및
