Disinfection of secondary water supply in sodium hypochlorite generator water plant

Product Details

When sodium hypochlorite comes into contact with water, it hydrolyzes to form hypochlorite and hypochlorite ions. Among them, hypochlorite has strong oxidizing properties and can destroy the protein and other enzyme systems of bacteria (viruses), thereby killing pathogenic microorganisms. Continuous disinfection effect with residual chlorine, simple operation, safer and more convenient than liquid chlorine, and cheaper than bleach powder.

Product advantage

-Accurate dosing, compared to chlorine gas, achieves residual chlorine content in the factory water, and consumes relatively less sodium hypochlorite solution. Due to the incomplete dissolution of chlorine gas when added to water, a certain excess coefficient needs to be considered. When the same amount is added, sodium hypochlorite has a good affinity for water and can dissolve in any ratio with water. The effect is better than adding chlorine gas, and the operation is safe and convenient to use; 

-The attenuation of residual chlorine in the pipeline network disinfected by sodium hypochlorite is slightly slower than that of free residual chlorine in chlorine gas disinfection. The main reason is that the hydrolysis of sodium hypochlorite in water is slower than that of chlorine gas, and it is alkaline and has a more sustainable disinfection ability;

-Compared with chlorine gas disinfection, sodium hypochlorite has lower safety risks, does not pose any leakage hazards to human life safety, and does not produce toxic or harmful by-products. Studies have shown that during sodium hypochlorite disinfection, dichloroacetic acid (DCAA) in the factory water is lower than that in liquid chlorine disinfection, while trichloroacetic acid (TCAA) is basically equivalent. When sodium hypochlorite is used for disinfection, trihalomethanes (THMs) in the factory water are lower than liquid chlorine, and carbon tetrachloride (CCl4) is basically equivalent to the two. Overall, the amount of sodium hypochlorite disinfection by-products is lower than that of liquid chlorine.

-Sodium hypochlorite will not cause severe corrosion to metal pipelines like chlorine reacts with water to form hydrochloric acid. At the same time, it is easy to transport and raw materials are readily available.

Technological process

The integrated sodium hypochlorite generator consists of six modules: inlet module, salt dissolution module, generation module, storage and hydrogen release module, dosing module, and control module.
