Filtration Media

GEBEL distributes a full range of Filter Media. The range includes AFM: (Activated Filter Media) for the most advanced requirements; Garnet Filter Sand and Gravel for sediment filtration and support beds; DMI-65 for reduction of iron and manganese; Calcite and Magnesium Oxide for pH adjustment; Ion Exchange Resins for cation and anion exchange; as well as Activated Carbon for reduction of reduction of chlorine, tastes and odours. 





AFM- Activated Filter Media


AFM filter media prevents the formation of toxic chemicals, making it safe to use in Swimming Pools, Aquaria, Zoological Parks, Aquariums & for Drinking Water.  AFM is self sterilising and does not incubate human pathogenic organisms such as Legionella and MRSA (Multi-Resistant Staff Infection). AFM is a much more effective barrier than sand to Cryptosporidium oocysts. AFM therefore prevents gastroenteritis and other serious intestinal diseases. AFM saves money on chemicals and power, and gives you much cleaner, brighter and safer water.




Activated Carbon


Activated Carbon

GEBEL Activated Carbon is charcoal that has been treated with oxygen to open up millions of tiny pores between the atoms.  By using of special manufacturing techniques, this then results in highly porous charcoals that have surface areas of 300 to 2,000m² per gram. These activated carbons are then widely used to adsorb odourous or coloured substances from gases or liquids. ­

Calcite is a crushed and screened white marble media which is an inexpensive solution to effectively neutralise acidic or low pH waters to a neutral, less corrosive effluent.  Calcite is a naturally occuring carbonate media.  Its main advantage is in its self- limiting property.  That is, when properly applied, it is able to correct pH just enough to reach a non- corrosive equilibrium.  Under normal conditions, it will not overcorrect.  When acidic waters come into contact with Calcite, the calcium carbonate is slowly dissolved to raise the pH which reduces the potential leaching of lead, copper and other metals that are typically found in plumbing systems.  Periodic backwashing will prevent packing; will reclassify the bed and maintain high service rates.  Depending on pH, service flow and water chemistry, the Calcite bed will need to be replenished periodically as the Calcite becomes depleted.  

As the Calcite's calcium carbonate neutralises the water, it will increase hardness- meaning that a softener may be necessary after the neutralising filter.

Calcite can be effectively combined with Magnesium Oxide.  This results in an increased ability to correct low pH.
