Activated Carbon
Activated Carbon is one of the most effective ways to improve water quality. Activated carbon plays a vital role in the process of providing safe and healthy drinking water. Municipal wastewater treatment involves using activated carbon to remove micro pollutants and impurities from all wastewater produced in towns and cities. It is made from diverse raw materials including coconut shell, various grades of coal and wood.
Nevtraco-I
Nevtraco-I is a filter material made from bryozoan lime. The material has high separating properties and is therefore particularly suitable for removing iron, ammonium, nitrite and more from drinking water. The structure of Nevtraco makes it ideal for filtering colloidal iron hydroxides. This structure also makes the material easy to backwash. The material has a gray/white colour, sharp edges, a rough surface and a fragile structure. Nevtraco water treatment lime is made from bryozo lime at Faxe Kalk A/S, where the lime is dried, pulverized and sieved. It is delivered in 20liter/25kg plastic bags.
Filox-R
Filox-R is used for removing iron, hydrogen sulfide, and manganese from water supplies. It is a media that utilizes an oxidation-reduction reaction and filtration process similar to Greensand, but at a much higher level of performance. Filox-R contains 80% manganese dioxide in an extremely unique cluster format for enhanced performance and maximized capacity. Filox-R out performs Greensand, Birm, etc. due to the purity of its particles, superior oxidation/filtration capacity and durability
Juraperle
Juraperle Calcium Carbonate is a granular media made up of 99.4% calcium carbonate. It has a superior performance to limestone due to its micro-crystalline structure. It dissolves very slowly, is free soluble constituents and has a low silica content. It is used in the pH correction of potable waters and the remineralization of soft and desalinated waters. During filtration, the free CO2 is converted to bicarbonate and calcium is dissolved respectively. By this, the pH and hardness rate is raised. In addition, the iron is also filtered. Because calcium is dissolved, the product must be filled regularly.
Clack Corosex
Clack Corosex, a highly reactive magnesium oxide, is used to fix and level the pH. It is acid-soluble, so it will dissolve gradually and must be replenished periodically. It can neutralize acidity 5 times more, compared to calcium carbonate. This results in greatly reduced chemical usage for the same pH correction. The pH correction can cause hardness minerals to precipitate out of solution, resulting in cementing or solidification of the Corosex mineral bed. Up flow service is generally recommended with hardness exceeding five grains per gallon.
Imerys Calcite
Imerys Calcite is a naturally occurring calcium carbonate media. One of the advantages of Calcite is its self-limiting property. When properly applied, it corrects pH only enough to reach a non-corrosive equilibrium. It does not overcorrect under normal conditions. Upon contact with Calcite, acidic waters slowly dissolve the calcium carbonate to raise the pH which reduces the potential leaching of copper, lead and other metals found in typical plumbing systems. Periodic backwashing will prevent packing, reclassify the bed and maintain high service rates. Depending on pH, water chemistry and service flow, the Calcite bed will have to be periodically replenished as the Calcite is depleted. As the Calcite’s calcium carbonate neutralizes the water, it will increase hardness and a softener may be necessary after the neutralizing filter.
Akdolit Magno-Dol CM
Akdolit Magno-Dol CM is a highly reactive half-burnt dolomitic filter material with a splintered granular form. It is used for the neutralization of potentially corrosive water to meet the requirements of the drinking water ordinance. The grain size 0.5 – 2.5mm (CM 1); 2.0 – 4.5mm (CM 2) respectively.

Clack Birm
Clack Birm filter media 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 filter media acts as an insoluble catalyst to enhance the reaction between dissolved oxygen (D.O.) and the iron compounds. In ground waters, 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 Fe2+ to Fe3+ 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 filter media is not consumed in the iron removal operation and therefore offers a tremendous economic advantage over many other iron removal methods.
