Catalytic filters

Magnor’s catalytic filters are custom-built and can be made of different materials depending on your needs. Catalytic filters use pyrolusite (manganese dioxide), which acts as a catalyst in the oxidation-reduction reaction of iron and manganese. These filters come with all the auxiliary equipment they require to function properly, including a control panel and an oxidant injection system.

We customize the design of our catalytic filters based on water contaminants, required flow rates, and other inputs.

Flow rates

At Magnor, we customize the design of our catalytic filters to accommodate flow rates from 10 US gpm to 3,000 US gpm depending on your needs.

Types of catalytic filters


Fibreglass tank filters are lighter than steel tank filters. Fibreglass filter tanks come in different sizes, with the widest measuring 1.6 m (63 in) in diameter.

This type of filter is suitable for small municipal, institutional, industrial, and commercial facilities.


Steel filter tanks are much sturdier than fibreglass ones. They can be custom-built and made of painted or stainless steel. Steel filters also come in bigger sizes, with tanks up to 3.66 m (12 ft.) in diameter.

Since they are bigger and heavier, these filters generally meet the standards of larger municipalities and big industry players.

Why use a catalytic filter?

Catalytic filters are used to remove the following contaminants:

Drinking water

In drinking water applications, catalytic filters are used by municipalities, communities, worker camps, and recreation and tourism centres to meet aesthetic and health standards as per provincial regulations in effect and Health Canada guidelines. Such standards are intended to protect the public and facilitate the maintenance of the entire distribution system and drinking water valves.

Process water

In process water applications, catalytic filters are used to eliminate the harmful effects of the above contaminants in various processes. 

For example:

  • Water used to rinse foods like vegetables must be free of such contaminants to avoid staining.
