What Is A Chlorine Dioxide Generator?

Chlorine dioxide (ClO2) is a chemical compound that is commonly used as a disinfectant and water treatment agent. It is effective at killing a wide range of microorganisms, including bacteria, viruses, and parasites, and is often used in public water systems, facility cooling towers swimming pools, and hospitals to kill harmful germs and keep water clean.

But if large-scale applications use chlorine dioxide to treat thousands of gallons of water, it doesn’t make financial sense to haul in drums of chemical. That’s where a chlorine dioxide generator comes in!

A chlorine dioxide generator is a device that produces chlorine dioxide through a chemical reaction. It typically consists of two chambers that hold solutions of sodium chlorite and an acid. When the two solutions react, they form chlorine dioxide gas, which is then dissolved in water to create an aqueous chlorine dioxide solution.

ClO2 generators provide the convenience of on-site production and the ability to produce precise PPM-concentrations of the chemical, at the necessary high volumes for large water use. Due to this scalability, chlorine dioxide generators widely used in a variety of industries.

Types of Chlorine Dioxide Generators

There are several different types of chlorine dioxide generators, including continuous flow generators and batch generators. Continuous flow generators produce a steady stream of chlorine dioxide, while batch generators produce a larger quantity of the chemical in a single batch. Both types of generators are commonly used in water treatment plants, facility cooling tower operations, hospitals, and other industrial settings.

There are also different chemical needs for different water treatment options.

Chlorine Dioxide Generators for Cooling Towers

Cooling Towers, for instance, use a blend of chlorate and reducing agents with sulfuric acid to produce chlorine dioxide at a high 95%-efficiency (PureLine’s CG Generator Series and PureMax chlorate blend is made for this application!).

Chlorine Dioxide Generators for Hospitals

Hospitals would typically use a higher 99.5%-efficiency, single pre-cursor chemical to create pure chlorine dioxide for treating biofilm and legionella bacteria (PureLine’s HP Series is utilized for this healthcare application).


Why Use a ClO2 Generator?

One of the main benefits of using a chlorine dioxide generator is that it allows for the on-site production of the chemical, rather than having to purchase and transport it from a separate location. This can be more cost-effective and convenient, particularly for larger facilities that use a lot of chlorine dioxide.

Another advantage of using a chlorine dioxide generator is that facility managers or water treatment professionals can configure the amount of chemical introduced into the water system with equipment that automatically measures and injects ClO2 into the water system; optimizing the parts-per-million (PPM) of chlorine dioxide, making sure that chemical residual levels are at proper concentrations for safe water use while killing germs and bacteria.

In addition to its use as a disinfectant, chlorine dioxide is also used in the bleaching of paper and textiles, and as a deodorizing agent. It is often used in the food industry to sanitize equipment and surfaces and can also be used to treat drinking water in areas where the water supply may be contaminated.
