Katalox Light





Media Description

High content (10%) gamma Manganese dioxide (MnO2) coated ZEOSORB


Katalox-Light® Removal methods:

1. Mechanical Filtration (fine particles, TSS, Turbidity etc.)
2. Catalytic precipitation and sorption (Fe, Mn, Cu, Pb etc.)
3. Adsorbtion (flocculant formation and adsorption of As, Heavy Metals, Radionuclides)


Filtration (≤ 3 µm) of:

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

Removal of:

♦ Iron (Inlet conc. up to. 100 mg/L)
♦ Manganese (Inlet conc. up to 20 mg/L)
♦ Arsenic
♦ Hydrogen Sulfide
♦ Uranium, Radium
♦ Heavy Metals
♦ Radionuclide

Best features:

♦ WQA Certified to meet ANSI/NSF 61 standard for Drinking Water applications
♦ Very high surface area
♦ High MnO2 coating (10%)
♦ Contains NO crystalline Silica
♦ No mandatory dosing required
♦ Light weight media – saves backwash water
♦ Replacement frequency every 7-10 years



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 Katalox-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 : m3/h
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).

Why Katalox-Light is

“The Best” compared to other products in the market?

Much higher gamma Manganese coating (10%) for better filtration, more service life, while keeping the bulk density close to the density of water 1000 kg/m³ (Katalox-Light Bulk Density: 1060 kg/m³) .

Heavier the media requires higher backwash rates and extra pumps (Energy) to backwash. Velocity of 60 – 98 m/h (25 – 40 gpm/ft²) Backwash and rinse rate is normal for Heavier media.
