Main benefits
How does zeolite work?
Natural zeolite has a particular affinity for ammonium ions and is used successfully in many industrial water treatment plants to remove high levels of ammonium ions from waste water.
It is also employed to remove heavy metal contamination from industrial effluent.
Common applications
Water treatment
- Industrial wastewater treatment
- Ammonium removal in wastewater
- Heavy metal removal
Filtration
- Replacement of sand in existing filters
- Combination with sand and activated carbon
- Production of high-purity water
Drinking water and public use
- Water potabilization
- Swimming pool filtration
- Industrial water treatment
Water reuse,
sustainability and research
Zeolites are used in the same way as sand and can replace sand in existing installations to give improved performance. They can also be used in conjunction with sand and/or other filter media such as activated carbon to produce very pure water or to clean heavily contaminated water.
With the new regulations on water recycling, zeolites offer the potential to produce clean usable water from almost any source.
Natural zeolites granules have been described by some as the world’s smallest filter. They are used for water potabilization, swimming pool filtration and industrial water treatment. Zeolites are also used in sewage treatment in many countries although they have yet to be fully exploited here in Spain. Given the importance of water as a natural resource and the shortages we face on a regular basis, the use of zeolites could make an important contribution to the efficient use of water in this country.
Many studies have been carried out which demonstrate the effectiveness of natural zeolites in water treatment applications
