♦ Total Suspended Solids
♦ Sediments
♦ Turbidity
♦ Organics
♦ Colour (some, organic)

Breakthrough in Iron

Removal Technology!

Real installations from different part of the world have been reported to remove unchallenged amounts of iron. In a few extreme cases multi-stage Katalyst-Light filtration systems have been used without the use of any chemicals to remove iron with inlet concentration of as high as 60 – 100 mg/L (ppm).

These astounding findings are being further investigated to find the correlation between removal limit and underlying ORP, pH and other possible governing characteristics.

Recommendation on Katalox Light System Calculation

Please enter Following Values :

Flowrate :
Iron(Fe) : mg/l (ppm) (Recommended inlet pH 7.5)
Manganese(Mn) : mg/l (ppm) (Recommended inlet pH 8.5)

Note: This is a standard calculation based on raw water pH 7.5 for iron removal and 8.5 for manganese removal.
If the raw water pH is not as mentioned above, then we highly recommend to increase the pH using Sodium Hydroxide (NaOH).

Advantages Of Katalyst-Light

Katalyst-Light is produced in Germany from ZEOSORB as a raw material. Katalyst-Light the lightest, to Greensand and Filter-OX, the heaviest. The Katalyst-Light media is the only catalytic media with the highest surface area which removes turbidity, suspended solids up to less than (< 3 microns).

The major advantage of Katalyst-Light is the slower head loss which leads to longer operation time. Katalyst-Light presents a rough and high surface characterized by a high number of pores and crevices. Accordingly, the structural and the texture is considerably different from Greensand Plus and Filter-OX. As a result, this allows slower head loss development, but at the same time causes higher pH and higher removal of iron and manganese without using any chemicals. Application of Katalyst-Light media can produce high-quality water without iron, manganese, and turbidity. Additionally, backwashing water demand is 60% less than Greensand Plus and Filter-OX.
