In the field of aquaculture, industrialized aquaculture methods have the characteristics of land conservation, water conservation, full automation, high-density intensification, and controllable emissions. The wastewater generated in the aquaculture system is centrally treated and recycled to achieve the goal of saving water resources and reducing pollution to the natural water environment; While ensuring the effective utilization of water and land resources, achieving economic benefits is in line with the requirements for sustainable development of the future aquaculture industry.

Industrial circulating water treatment solution:

Fish produce feces and other waste during their growth, which enter the sedimentation tank through pipelines to settle coarse particles such as feces; The water that comes out immediately goes through a biochemical reaction system, where beneficial biological bacteria are cultivated to decompose harmful substances in the water and remove toxins such as nitrite and hydrogen nitrogen from the aquaculture water. The effluent enters an integrated aquaculture water treatment equipment for high-precision water quality filtration, removing suspended solids (fish feed residue, fish and shrimp feces), organic matter (ammonia nitrogen, protein, phosphorus, etc.), heavy metal ions, and automatically aerating the water to increase oxygen content, dissolved oxygen, and activation; The filtered water enters the ultraviolet sterilizer, during which 99% of the virus is eliminated.

Specification of Industrial Aquaculture Water Treatment Equipment:

Characteristics of industrialized aquaculture water treatment:

1. Good effluent quality: The effluent quality is better than the first level standard of "Discharge Requirements for Seawater Aquaculture Water" (SC/T9103-2007);

2. High efficiency: The removal rate of total inorganic nitrogen is ≥ 85%, and the removal rate of active phosphate reaches over 90%;

3. The dissolved oxygen in the treated water is ≥ 7.8mg/L (reaching saturation), and the water quality is fresher and activated.

4. Effectively remove foam in water - that is, remove organic substances (including phosphorus, ammonia and other foaming substances) in water to maintain good water quality.

6. All water is treated without pressure, and the head of the circulating water pump is generally 5-6 meters, with low energy consumption and operating costs only 1/10~1/15 of traditional water treatment systems.

7. The equipment is manufactured using UPVC high-strength plastic, which is resistant to seawater corrosion, requires no maintenance, and has a warranty of 40 years.

Wuxi Jiangdaliansheng Water Treatment Technology Co., Ltd. targets domestic demandSeawater and freshwater factoriesWe have researched and developed an industrialized aquaculture circulating water treatment system and related water treatment equipment that is suitable for China's national conditions. While ensuring that the treated water quality meets the standards, we have significantly reduced operating energy consumption, saving farmers/units on aquaculture.
