Versatile Iron Removal Media - Potent, and Light Weight
Watch Water's Katalox Light® combines the versatility and high performance characteristics of heavier solid manganese dioxide media with the light weight properties of a coated media, resulting in a economical treatment option for realtively high levels of iron, manganese, and hydrogen sulfide that is easy to backwash. This results in substantial water savings, making Katalox Light® a good choice for low yield wells.
Katalox Light® is an insoluble catalyst that causes dissolved iron and manganese to oxidize to form ferric hydroxideand manganese oxide particles which are removed through mechanical filtration in the media bed. Katalox Light® is not consumed in the reaction and it does not need to be chemically regenerated. Katalox Light® is composed of a manganese dioxide coated zeolite and contains about 10% manganese dioxide.
- 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)
