  • It is a new type of aquaculture mode, through a series of water treatment units, the wastewater generated in the aquaculture pond is treated and recycled again. The main principle of RAS is to integrate advanced technologies in environmental engineering, civil engineering, modern biology, electronic information and other disciplines to remove residual bait manure, ammonia nitrogen (TAN), and nitrite nitrogen (NO2--N) in aquaculture waters. ) And other harmful pollutants, for the purpose of purifying the breeding environment, the process of using physical filtration, biological filtration, CO2 removal, disinfection, oxygenation, temperature adjustment and other treatments to re-enter the purified water body into the aquaculture pond. It can not only solve the problem of low water resource utilization, but also provide stable, reliable, comfortable and high-quality living environment for breeding organisms, and provide favorable conditions for high-density breeding.
