Plan for an annual production of 100 tons of tilapia

Project location: Africa, Congo Breeding species: Tilapia Customer situation and demand: The production of 100 tons of tilapia, each finished fish about 1KG, there is a river next to the farm, the current site is empty. ZHRAS engineers design according to customer requirements, the growth cycle of tilapia can be farmed for about two cycles a year, that is, the production of 50 tons in a cycle can reach 100 tons in a year. According to ZHRAS calculation, the scheme is designed into 20 fish ponds, the specifications of each fish pond: Φ6000x1450mm. In consideration of transportation, ZHRAS used a cement tank this time. This system adopts the ZHRAS process, as follows:

System process description: Circulating aquaculture tilapia, breeding density requirements of up to 40-60 kg/m3, the relative breeding density is relatively high. Excrement and erbium residues are relatively more, and these are the main causes of water quality deterioration, which needs to be treated and discharged in the first time, so each aquaculture tank is equipped with a separate vertical flow filter to discharge large particles of dirt in the first time, and the second filtration treatment of fish feces and erbium residues through the micro-filter can remove most of the solid suspended matter. The water is pumped by submersible pump to the degassing equipment to remove carbon dioxide from the water to stabilize the PH in the water, and then enters the biological system for bacteria cultivation, decomposition of ammonia nitrogen and nitrite. The water in the biological system is sterilized and then self-flow back to the breeding tank. Because the breeding density is relatively high, it is necessary to oxygenate the breeding tank directly to reduce waste and improve the oxygen utilization rate. The system has the advantages of low operating cost (using ZHRAS company's design advantages to reduce motor power and reduce energy consumption), low maintenance cost (less maintenance), easy to move and less floor space.
