What role does PAC play in aquaculture

Among the chemicals used in water diversion and aquaculture, most products contain such components as sodium thiosulfate and polyaluminium chloride. Sodium thiosulfate and polyaluminium chloride are two chemical products mostly used in water works, sewage treatment plants, chemical plants and hospitals, and can be purchased in general chemical reagent stores. They are inexpensive, have good effects and have little side effects. Therefore, they should be used as the target of water improvement and water transfer for ordinary aquaculture households. Nowadays, most of the water regulating and priming drugs on the market contain sodium thiosulfate or polyaluminium chloride, which is a good medicine for regulating water quality, detoxifying and killing blue (green) algae.

Treatment of aquaculture tail water.

The quality of pond aquaculture water contains a lot of organic substances such as breeding residues and fish excrement, which leads to the decrease of water transparency, eutrophication of water quality, and direct discharge of water will cause environmental pollution. Therefore, it is necessary to filter and purify the aquaculture water in pond, and then discharge or recycle it after meeting the discharge standard. The use of polyaluminium chloride can make colloidal particles which are difficult to precipitate in water rapidly, coagulate, agglomerate and flocculate into larger particles to precipitate, significantly reduce COD and BOD of water body, and greatly improve the efficiency of tail water treatment.

Water quality treatment in special weather.

Summer high temperature and rainy, easy to cause flooding disasters, a large number of mud, various types of surface debris easy to flow into the aquaculture pond, resulting in turbidity of the water body, thus stimulating cultured fish, resulting in stress death. At this time, adding polyaluminium chloride can rapidly settle sediment and organic matter in water body, avoid turbidity of pond water, quickly restore transparency of pond and improve oxygen generation ability of phytoplankton. At the same time, after the flood disaster, the water body pH is easy to be excessive acid, and the polyaluminium chloride pH is alkaline, which can also play a role in stabilizing the water body pH.

Deodorization and sterilization

Polyaluminium chloride has the functions of deodorizing, antiseptic and disinfection in aquaculture. It can decompose oxides to produce organic matter, organic sulfide, organic nitrogen, etc., absorb and decompose toxic substances such as ammonia nitrogen and nitrite, and quickly kill harmful organisms and prevent the growth of corrupt microorganisms.

Not for long-term use.

Polyaluminium chloride, sodium thiosulfate and other flocculants are pure water flocculants, which can only be used to temporarily alleviate water quality problems and can not be used as water transfer products for a long time.
