RAS (Recirculating Aquaculture System) is a high-efficiency closed-loop farming solution for commercial aquaculture. It features automatic water circulation and purification, effectively solving traditional farming problems such as high water consumption, unstable water quality, seasonal restrictions and low breeding density.
Equipped with full-stage filtration and treatment modules including drum filtration, biofiltration, protein skimming, UV sterilization, oxygen and temperature control, the system removes waste and harmful ammonia & nitrite. It achieves 90%+ water recycling rate, saving water cost and reducing wastewater discharge.
Our automated, space-saving RAS supports high-density indoor farming for fish, shrimp and crab. It enables year-round production without climate and regional limits. Stable water quality lowers disease rate and drug usage, raising survival rate and product quality for sustainable high-yield farming.
