Small Scale Recirculating Aquaculture Systems

What basic equipment you need?

1. Drum Filter: Remove residual feed and fish feces in the water

2. Biological Filter: Convert toxic ammonia nitrogen into low toxic ammonium nitrate

3. Aeration separation: Remove harmful gas in the water (CO2, H2S etc.), and increasing oxygen

4. UV Sterilizer: To kill harmful bacteria in the water to avoid fish diseases and parasite

5. Water Temperature Controller: To adjust the water temperature to the most suitable growth temperature

Except above equipment, you can also put below equipment into your RAS to meet a more perfect andefficientsystem.

1. Protein Skimmer: Remove more than 90% small suspension particle and soluble colloidal organic matter, can work as Ozone reaction tower, and inject Ozone to disinfect water.

2. Ozone Generator: Offer Ozone to disinfect water. It is a powerful oxidizing agent that can be used to break down compounds. Ozone must be used with caution since it is directly toxic to aquatic life and may form harmful biproducts (hypochlorite, hypobromite).

3. Residual Ozone Remover: To remove residual Ozone in the water, to avoid it poisons the fish.

4. Oxygen Generator + Oxygen Cone: Oxygen Generator produces Oxygen and Oxygen cone mix it into water, increase dissolving Oxygen amount.

5. Air Blower + Air Diffuser or Air Stone: Air blower blow air to air diffuser or air stone, increase dissolving Oxygen amount in fish tanks.

Work flow of  Indoor Water Filtration Systems 

First, water in fish tank flow to ZH-PM drum filter, ZH-PM drum filter will remove the residual feed, feces and large particles suspended solids, then circular pump to pump needed water into ZH-NPS protein skimmer.

ZH-NPS protein skimmer will remove the suspended solids, water-soluble colloidal, cellulose, protein, residual feed, feces and other organic matters, at the meantime, to inject Ozone, use Ozone’s stronger oxidization property, oxidative damage and breakdown cell’s enzymes to kill different kinds of Pathogens quickly, and decolor, remove smell, improve the water quality at the same time. After this, water will flow to ZH-SBF biological filter.

ZH-SBF biological filter was selected specific biological filter media. First aquaculture water goes through precipitation, coarse filtration and precise filtration. Then go through secondary biological filter, to decompose NH3-N, NO2-N and NO3-N which are the most harmful gas in aquaculture, to meet standards of aquaculture safety.  After this, water will flow to ZH-CP Degassing & UV sterilizer

ZH-CP Degassing & UV sterilizer can use its internal UV light to disinfect and kill the bacteria. Nano aeration device in the ZH-CP degassing & UV sterilizer can remove the CO2 and other harmful gas in the water in time. After this, water will flow back to fish tank completes a cycle.
