Recirculating aquaculture

With the development of the aquaculture industry and the requirements for energy conservation and environmental protection in water resource utilization, recirculating aquaculture has received more and more attention in recent years.

During the recirculating aquaculture process, organic matter such as feces, fish mucus, and carcasses will be produced. Decomposition and fermentation will produce ammonia nitrogen, nitrite, hydrogen sulfide, and other harmful substances, which will deteriorate water quality and fish survival. Therefore, it is necessary to conduct breeding Water is treated.

The purpose of developing recirculating aquaculture

Improve water quality management: Recirculating aquaculture systems can better control water quality and reduce wastewater discharge through water circulation and treatment. This helps reduce the concentration of pollutants in water bodies, provides a more suitable growing environment and reduces the risk of disease transmission.

Water conservation: Recirculating aquaculture systems can significantly reduce water consumption because water is no longer consumed in large quantities but is recycled. This is especially important in arid areas or places with limited water resources.

Improve production efficiency: By controlling water quality and environmental conditions, recirculating aquaculture can improve the efficiency of breeding production. Stable water quality and temperature can promote biological growth, reduce mortality, and improve the yield and quality of cultured products.

Reduce environmental impact: Recirculating aquaculture systems can reduce wastewater discharge and reduce negative impacts on the surrounding environment. This includes reducing the release of pollutants such as ammonia nitrogen, nitrite, and solid particles, reducing pressure on water ecosystems.

Energy conservation: Although recirculating aquaculture systems require energy to maintain water circulation and treatment processes, they are generally more energy efficient than traditional open culture systems because they can better control water temperature and other environmental parameters.

 Selection of MBBR biological filler

MBBR should choose models with large specific surface area and lightweight as much as possible to increase reaction efficiency and reduce aerator agitation energy consumption, such as MBBR61/64/78/92, which Juntai has currently provided in hundreds of circulating aquaculture projects at home and abroad. The project application of MBBR technology includes the cultivation of eels, shrimps, loaches, sturgeons, grouper fish dishes and more than ten kinds of fish.
