Tilapia Farming RAS

RAS Recirculating aquaculture system 

Recirculating Aquaculture System (RAS) series of treatment processes is utilized to maintain water quality in intensive fish farming operations. These steps of Recirculating Aquaculture System (RAS) are often done in order or sometimes in tandem. 
After leaving the vessel holding fish the water is first treated for solids before entering a biofilter to convert ammonia, next degassing and oxygenation occur, often followed by heating/cooling and sterilization. Each of these processes can be completed by using a variety of different methods and equipment, but regardless all must take place to ensure a healthy environment that maximizes fish growth and health.
