Membrane filtration coupled with chemical precipitation to treat recirculating aquaculture system effluents.
Effluents from recirculating aquaculture systems (RAS) contain high concentrations of nitrogen and phosphorous wastes and thus often require proper treatment to prevent potential detrimental impacts on receiving water bodies. The purpose of this study was to evaluate the feasibility of membrane filtration coupled with chemical precipitation as a pretreatment step with emphasis on phosphorus rem...
متن کاملMicrocontrollers in Recirculating Aquaculture Systems
Closed-system aquaculture presents a new and expanding commercial opportunity; however, presently there are few profitable commercial operations. Intensive aquaculture systems require a sufficient supply of oxygen and nutrients in temperaturecontrolled water with a means of removing wastes from the system. In properly controlled recirculating aquaculture systems, stocking rates of up to one-hal...
متن کاملClosed water recirculating system for fish rearing equipped with bioreactor capable of simultaneous nitrification and denitrification.
Five crucian carp, Carassius auratus langsdorfiicarps had been reared in a closed water recirculating system. The system was equipped with the compact bioreactor using the plate gels capable of both nitrification and denitrification in a single unit. Ammonia and nitrite concentrations in the rearing water had been maintained below 0.05 mg-N/L, and nitrate concentration also controlled between 2...

متن کاملSlow Sand Filtration for Cercarial Control in North Cameroon Village Water Supply
People of North Cameroon must look for water at great distances from their homes during the dry season of the year. To provide water closer to villages series of internationally and bilaterally financed dams are being built to impound water in reservoirs. The Ministry of Health of the Government of the Republic of Cameroon is concerned that the dams do not increase health problems. One concern ...
