- KATALOX-Lite filter media
What is Katalox Light®?
KATALOX LIGHT ® is a new brand of revolutionary advanced filtration media completely developed in Germany. It‘s composition simply makes it outstanding against the contemporary filter media available in water treatment industries, like sand, BIRM, Greensand Plus, Manganese Greensand etc. KATALOX LIGHT ® is manufactured in Germany. KATALOX LIGHT ® is engineered with a unique MnO2 coating technique on ZEOSORB®, providing it lightweight, higher filtration surface, more service life and more reliable performance (filtration down to 3 µm) than any other existing granular filter media. KATALOX LIGHT ® is being used in numerous system for residential, commercial, industrial and municipal applications worldwide, for High-level filtration, colour and odour removal, Iron, Manganese, Hydrogen sulphide removal, efficient reduction of Arsenic, Zinc, Copper, Lead, Radium, Uranium and other radionuclides and heavy metals. KATALOX LIGHT ® is Certified to NSF/ANSI-61 standard for drinking water applications and has met the ANSI/NSF 372 Lead-free compliance.
- BIRM filter media
Birm® is an efficient and economical media for the reduction of dissolved iron and manganese compounds from raw water supplies. It may be used in either gravity fed or pressurized water treatment systems.
Birm acts as an insoluble catalyst to enhance the reaction between dissolved oxygen (D.O.) and the iron compounds. In groundwaters, the dissolved iron is usually in the ferrous bicarbonate state due to the excess of free carbon dioxide and is not filterable. Birm, acting as a catalyst between the oxygen and the soluble iron compounds, enhances the oxidation reaction of Fe++ to Fe+++ and produces ferric hydroxide which precipitates and may be easily filtered.
The physical characteristics of Birm provide an excellent filter media which is easily cleaned by backwashing to remove the precipitant. Birm is not consumed in the iron removal operation and therefore offers a tremendous economic advantage over many other iron removal methods. Other advantages of Birm include; long material life with relatively low attrition loss, a wide temperature performance range and extremely high removal efficiency.
Negligible labour costs are involved because Birm does not require chemicals for regeneration, only periodic backwashing is required. When using Birm for iron removal, it is necessary that the water: contain no oil or hydrogen sulphide, organic matter not to exceed 4-5 ppm, the D.O. content equal at least 15% of the iron content with a pH of 6.8 or more. If the influent water has a pH of less than 6.8, neutralizing additives such as Clack Corosex®, Calcite or soda ash may be used prior to the Birm filter to raise the pH. A water having a low D.O. level may be pretreated by aeration.
