Shrimp and Tilapia RAS indoor intensive fish farm equipment recirculating aquaculture system for fish faming
Recirculating aquaculture system
RAS are used in home aquaria and for fish production,shrimp production or other speci where water exchange is limited and the use of biofiltration is required to reduce ammonia toxicity. Other types of filtration and environmental control are often also necessary to maintain clean water and provide a suitable habitat for fish.
The main benefit of RAS is the ability to reduce the need for fresh, clean water while still maintaining a healthy environment for fish. To be operated economically commercial RAS must have high fish stocking densities, and many researchers are currently conducting studies to determine if RAS is a viable form of intensive aquaculture.
Advantages
● 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.
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.
Protein Skimmer
Be used for improving water quality
Removing fine organic matters and dissolved organics efficiently.
RAS Application
