Sterilization algaecide (WS B-402d)

WS B-402d is a broad-spectrum, high-efficiency, low-toxicity, non-oxidizing biocide. It is an ideal bactericidal algaecide for industrial circulating cooling water. It is widely used in cooling, circulating water systems such as petroleum, chemical, metallurgy and central air conditioning. . It can also be used in combination with other non-oxidizing biocides for synergistic effect.

◇ Introduction:

   WS B-402d is a broad-spectrum, high-efficiency, low-toxicity, non-oxidizing biocide. It is an ideal bactericidal algaecide for industrial circulating cooling water. It is widely used in cooling, circulating water systems such as petroleum, chemical, metallurgy and central air conditioning. . It can also be used in combination with other non-oxidizing biocides for synergistic effect.


   By contact with microorganisms, this product can quickly inhibit its growth, leading to the death of biological cells. It has strong inhibition and killing effect on common bacteria, fungi and algae in circulating water. It has high killing efficiency, good degradability of active ingredients, no residue, and low cost.
