RAS Process

RAS Water Treatment Processes

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. 

Drum Filer

Be used for the Solids Filtration

Able to remove 42%~75% of the total particales from the aquaculture water vlume.

UV sterilizer

Be used for the disinfection

UV light waves emitted to various bacteria in the water 

and make them lose the ability to reproduce and die out. 

Product Description

About eWater oxygen cone

Our oxygen cones are applied to dissove the oxygen in the Water.

Their shape makes the saturation efficiency very high , up to 95%. Water and oxygen enter at the top of the cone at 

relatively high speed. The stream of water pushes the oxygen bubbles down until they completely dissolve.


1).High performance and durable with high oxygen utilization rate ( over 90%)
2).Serialized prodcuts for various customer needs(20~120 m3/hr)

3). Specialized design for high density farming(over 50kg/m3)

4.Easy installation
