Recirculating Aquaculture System

Introduction Of TH-RAS Recirculating Aquaculture System 
System Application Scope: 
All kinds of fish and shrimp in seawater or freshwater aquaculture; 
Pond culture, industrial aquaculture, circulating water culture; 
Surface water purification treatment.  

System Composition:  Fishpond(User supplied)
Biochemical reaction system
TH Integrated circulating water treatment equipment
Ultraviolet sterilization equipment
Temperature control system(User supplied) 

System Characteristics:  
1. High Integration Protein separation, aeration, biological reactions and biological filtration, these four functional modules are merged together. One-time completes their work, which can save 3/4 of the electricity consumption, and has realized automatic hydraulic control. 
2. Long Cycle Period Cycle period: 4 hours a time, Cycle times: 6 times a day. 
3. Energy Conservation&Consumption Reduction Less Power Equipment: All non-pressurized water treatment system whose usage of the lift generally adopts 5-6 meters of circulating water pump. Operating cost is 1/10-1/15 of the traditional water treatment system. 

Less Sewage Generated: The equipment can carry out real-time automatic back flushing according to the pollution of filter layer; Day backwashing water(Displacement of water) is 3-5% of the total amount of water. Washing power up to 32L/m2•s. Backwash time is less than 3 minutes. There is no electric energy loss when the back flushing. 

No need to replace biological filter: The equipment back flushing is thorough, without the blockage hidden danger, and you only need to add a small amount of filter material each 5-6 year. 4. Good Treatment Effect High Filter Precision:
  •The unique multi-layer fine filtration media, can effectively remove harmful substances in water, including phosphorus, ammonia nitrogen, protein and other substances.
  •After treatment the water turbidity is less than or equal to 1 degrees. Color is less than or equal to 15 degrees, and visibility is more than or equal to 2 meters.
  •Accord with the standard of Water Quality Standard Of Fishery (GB11607-89). 
Water Dissolved Oxygen Saturation After The Treatment:
  •The equipment has two times aeration dissolved oxygen and oxygen content can up to 6-8mg/L, which the quality of water is very fresh. 5. Long Service Life Long Service Life:
  •The water treatment equipment adopts UPVC material, no rust, moisture resistance, corrosion resistance.
  •Strict control of materials and manufacturing processes, and quality assurance.
  •Service life of up to 40 years (In line with national industrial policy of using plastics replace the steel (copper), energy saving, consumption reduction and environmental protection. )
Without vulnerable parts:  
•There almost won't break down running for decades, which has reduced maintenance costs. 6. Without Special Operation Hydraulic automation design, no electricity, no valves, no operation, no need for special management, saving 100% manpower. 7. Saving Construction Cost Compact structure, modular design, convenient transportation, installation and movement, and reducing the cost of land. 
System Design:  Users need to provide the parameters:
  Total water volume, Source of water(Fresh water or sea water),
  Aquaculture species and density. 
We will provide you with the design scheme of recirculating aquaculture system based on your parameters.
