What is Catalox?

Catalox is a black, granular particle with a mesh size (mm) of 0.85 – 2.36 used as a granular filter media for water treatment. The filter media can either be a classical filter or catalytic media in a water filter system. Catalox filter media can work on its own or with an oxidant to help with the reaction between the oxidant and prevalent dissolved oxygen with the water contaminants like sulfide, iron, and manganese.

How Does Catalox Work?

The granular media works by stopping oxidized forms of these contaminants. It prevents sulfide, iron, and manganese from passing through the filter media bed. The dense media stops any of the manganous manganese from going through.
Catalox is a filter media commonly used before water softener in a water filter system. When working in the right conditions, it will yield great results and prolong the service life of the media.

How to Maintain Catalox Filter?

Properly backwashing the filter media will remove any of the absorbed contaminants in the media bed. With periodic backwashing and addition of an oxidant, it will break loose any of the impurities while encouraging continuous regeneration for longer service life.

What are the Advantages of Catalox Filter Media?

There are many good reasons why you should choose the filter media as a part of your water filtration system. Among these are the regeneration of the media without the use of any chemical, absorption of MnO2, high flow rates with low pressure drop, and its ability to be used with an oxidant. Above all, it is effective in reducing the presence of manganese, iron, and sulfide in tap water. Catalox is also a low-maintenance type of filter media.

What are Its Operating Conditions?

The filter media works best in water with a pH level of 6.0 to 9.0 and with a bed depth of between 36 to 48 inches. The freeboard is about 70% of the bed depth and backwashing must be done every 24 hours. Under the right conditions, the removal efficiency of the granular media for iron and manganese are 95-99% and 99% respectively.
