EQUIPMENTS OR MACHINERIES USED IN RECIRCULATING AQUACULTURE SYSTEM

LIST OF THE MACHINERIES OR EQUIPMENTS USED IN RECIRCULATING AQUACULTURE SYSTEM 

                                   In this blog we just discuss the necessary equipments needed for Recirculating Aquaculture System setup.On next we will discuss in details of each items and which type of material we should used for best ras setup like which types of tanks and of what material we can use for best fish growth and many more details about other systems........

  • FISH TANKS: Fingerlings of size 1-2 inches or more are introduced and grown up to marketable size in this fish tanks. Fish tanks may be circular,conic and rectangular, tanks have also central drainage system.Fish tanks may be of cement.stainless steel or  High-density polyethylene (HDPE) tanks or polyethylene high density (PEHD) tanks.The size that i.e the volume of tanks depends on the farmers fish production capacity.

  • WATER PUMP: Pumps are needed for the water recirculation in the RAS system. Pump power rating is in horse power(HP) and 1 HP =746 watt
PUMP

  • DRUM FILTER: It filters all the fish waste and residual feed using mesh.Drum filters are ideal for the removal of fine suspended solids in Recirculating Aquaculture Systems where water is being reuse.

  •  PROTEIN SKIMMER: Protein Skimmer or Foam Fractionation is an effective filtration tool when used with closed Recirculating Aquaculture Systems. Saltwater systems can benefit from it especially in those carrying high fish loads.Protein Skimmer physically removes organic compounds before they begin to decompose.This reduces the load on the biological filter and improves the water's redox potential.

  • BIO FILTER : It is used to convert ammonia to nitrite and from nitrite to nitrate  A biological filter is a natural filtering system consisting of helpful bacterial colonies that, through a cycling process, convert pollutants in water to harmless nitrate.

  • De GASSING CHAMBER: This is used to remove any unwanted gases like nitrates and co2 from water before re-entering into fish tanks.

  • U.V STERLISER:  UV steriliser is used to make water clean and free from disease causing entities.It makes the system perfect and so mortality rate becomes nearly negligible.

  •    OZONE GENERATOR:-Ozone generator is easy operating,with high reliability,wide use its sterilization function can be applied in Recirculating Aquaculture Systems.Ozone generator itself contains oxygen generating system,air refrigerator which use air as raw material,without any accessories.

  • ROOT-BLOWER- It supply oxygen to the bio-media and the fish tanks.

  •    OXYGEN CONE : Oxygen cone also called aeration cone  is specially designed for Recirculation Aquaculture Systems.It can be used with pure oxygen generators or oxygen cylinder and supplies more high dissolved oxygen for fish farming.

  •   CHILLER AND HEATER MACHINES : These are used when temperature of water is very cold or hot as compared to particular fish species adaptation capacity.



  •   ELECTRIC CABINET : All the electric works and there systems are joint in this electric          cabinet.

  • PIPES AND VALVES: Pipes and Valves are necessary equipment in Recirculation Aquaculture Systems.

  • Generator: As power supply is needed 24 hours so for a power supply back up generator is used.

  • A closed shed is required to established  a  RAS unit.
