top selling iron removal media - versatile, potent, and light weight

Watch Water's Katalox Light® is a remarkable new iron removal media from Germany. It combines the versatility and high performance characteristics of Filox™ media with the light weight properties of Birm®, resulting in a economical treatment option for high levels of iron, manganese, and hydrogen sulfide that is easy to backwash. This results in substantial water savings making Katalox Light® an ideal option for wells with low water yield.

Like most iron removal medias, Katalox Light® acts as an insoluble catalyst to enhance the reaction between dissolved oxygen and the iron compounds to form ferric hydroxide which is then removed through mechanical filtration in the media bed. As a catalyst, Katalox Light® is not consumed in the iron removal process and it does not need to be regenerated. Also like most other iron removal media, the active ingredient in Katalox Light® is manganese dioxide. Kaltalox Light® is composed of a manganese dioxide coated zeolite, containing about 10% manganese dioxide, far higher than Birm® but less than Filox™.

  • concurrent treatment of iron, manganese and hydrogen sulfide (rotten egg odor)
  • low back wash flow rate
  • longer life and much more active ingredient than Birm®
  • excellent filtration capabilities (down to as low as 3 microns under ideal conditions)
  • regeneration generally not required
  • WQA validated to ANSI/NSF 61 and 372 standards
  • high tolerance of oxidizers such as chlorine, hydrogen peroxide, and potassium permanganate (which can be used to boost performance in extreme treatment cases)
  • removal of arsenic and certain heavy metals possible through co-precipitation (see below)

Where iron removal is a pre-treatment to an arsenic filter, Katalox Light® is a good choice as an iron removal media as it will convert trivalent arsenic to pentavalent arsenic to enhance removal at subsequent treatment steps. Where the iron level is at least 20 times the arsenic level, indirect removal of arsenic is also likely through adsorption to the ferric hydroxide particles created during iron removal (co-precipitation), so a dedicated arsenic filter may not even be required. Follow-up testing should be done to confirm satisfactory arsenic reduction. We strongly recommend that you contact one of our Certified Water Technicans to discuss your application in detail if you plan to use Katalox Light® for arsenic removal as there are numerous factors that can impact performance.

Customer Questions & Answers

Question:What is the difference between the rec service flow rate and the max rec flow rate

Recommended service flow rate is the typical service flow rate you would run through the system day to day, max service flow rate would be in cases were you have a higher volume of water temporarily going through the system (guests over for instance). It's the maximum flow rate you should run through the system while still getting adequate contact time

Question:Service Flow Rate

Service flow rates will depend on your tank size and the amount of Katalox media you are using. Recommended service flow rates for different tank sizes can be found in the chart above.
By HomePlus Water on Feb 05, 2024

Question:Is the backwash flow rate controlled by an onboard temperature sensor in the unit or must it be set by installer?

The backwash flowrate is set with a physical flow restrictor in the drain line connection. The appropriate flow restrictor is installed when the system is assembled in our warehouse.
