RAS Description


eWater RAS processes and the equipment necessary

A series of treatment processes is utilized to maintain water quality in intensive fish farming operations. These steps 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.

Advantages of RAS


▶Reduced water requirements as compared to raceway or pond aquaculture systems. 

▶Reduced land needs due to the high stocking density.
▶Site selection flexibility and independence from a large, clean water source.
▶Reduction in wastewater effluent volume.

▶Increased biosecurity and ease in treating disease outbreaks.
▶Ability to closely monitor and control environmental conditions to maximize production efficiency. Similarly, independence from weather and variable environmental conditions.
