Sodium Benzotriazole in Industrial Water Treatment: Small Dose, Big Protection

 In industrial water systems, copper alloys are often found in condensers, heat exchangers, cooling coils, and piping. These components are vital to production, but they can corrode over time. The result? Reduced heat transfer, leaks, unscheduled shutdowns, and costly repairs.

Sodium Benzotriazole is one of the most effective and widely used corrosion inhibitors for copper and copper alloys in water treatment. It works by forming a protective film on metal surfaces, blocking corrosive species such as oxygen and chlorides from reaching the metal.

Where it is used:

  • Cooling tower systems

  • Closed-loop cooling and heating systems

  • Industrial water circuits

  • Process water systems

  • Boiler feedwater and condensate lines where copper alloys are present

Because Sodium Benzotriazole is water-soluble, it is easy to dose and disperse. It is effective at low concentrations, making it economical for large-volume water systems. It can also be combined with other inhibitors, such as phosphonates, molybdates, or silicates, to create synergistic corrosion control programs.

For plant managers and water treatment specialists, adding Sodium Benzotriazole can mean fewer maintenance headaches, longer equipment life, and more stable operations.

Shandong Kairui Chemistry Co., Ltd. manufactures and supplies Sodium Benzotriazole for water treatment applications. With reliable production and export experience, the company supports customers with product data, samples, and flexible packaging options.

Shandong Issues Water-Saving Industry Development Plan, Targeting a Scale of 100 Billion Yuan by 2027

  On June 23, journalists learned from the Shandong Provincial Water Resources Department that the department, together with the Shandong Provincial Development and Reform Commission, Shandong Provincial Department of Science and Technology, and five other departments, recently issued the "Shandong Water-Saving Industry Development Plan," proposing ideas, layout, direction, and pathways for the high-quality development of the water-saving industry. By 2027, the province's water-saving industry scale is expected to reach 100 billion yuan , and by 2035, the scale is set to double over the decade. Key targets: By 2027: Form more than 10 featured and competitive water-saving industrial clusters (parks); cultivate more than 2 national or provincial water-saving technology innovation platforms; establish a pilot zone for high-quality development of the water-saving industry in the Yellow River Basin. By 2035: Double the industry scale compared to 2027; build mor...

what is Acetone Oxime use for?

  Acetone oxime is a ketoxime. It is usually used as oxygen scavenger in power plants, passivator in industrial cleaning and anti-corrosion projects, passivating agent in water treatment chemicals, etc. Chemical deoxidant/deoxidizer/deaerator for feedwater. Oxygen removal effect is the same as hydrazine, and the toxicity is greatly reduced. Protecting / protective agent for thermal equipment shutdown. Because of its good reducibility, its aqueous solution can form a good magnetic oxide film on the surface of steel, effectively delaying the corrosion of thermal equipment out of service. Passivation effect (corrosion protection / inhibitor). Use this product instead of toxic reagent sodium nitrite, hydrazine as passivator for thermal equipment after pickling, small pollution, good film quality. diesel fuel primer, intermediate (organic synthesis).
