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)

Best features:
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.

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).

*This calculator has been designed based on real time data obtained from system installation worldwide.
*The contamination concentration and the filtration rate is best-fit approximation and is subject to be updated.
*This calculation is only a recommendation for system design. Please do not forget to read and follow the instruction given in our Katalox Light product literature.
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.
