Zeolite for water filter

Natural zeolite allows the filtration of drinking water in deep bed filters without the need to combine it with other filter media, since it meets the specifications of giving depth to the filter bed and retaining particles between 5 and 10 microns.

Natural absorbent due to its high degree of hydration. Excellent stability in its crystalline structure when dehydrated. Its density is low and it retains a large volume of voids when dehydrated.

High capacity collector, retains particles up to 5 microns.

The cation exchange properties of zeolite neutralize certain elements. Uniform molecular channels are sorted in order upon dehydration.

High absorption capacity of gases and vapors. It has catalytic properties and ion exchange capacity.

Zeolites are porous minerals of volcanic origin, consisting of a scaffold of silicon and aluminum tetrahedra, arranged in an orderly fashion and linked by oxygen atoms, which are the skeleton of their crystalline structure. in the open spaces of the latter, whose pore diameter ranges from 3 to 10 anstroms, water molecules are introduced without participating in the cohesion of the network.

Upon dehydration, the structure forms open three-dimensional networks and its compounds are arranged in channels of molecular order size, presenting an excess of negative charge as a consequence of the isomorphic substitution of Si4+ by AI3+, thus developing its gas and vapor absorption capacity and allowing ion exchange.

In this phenomenon, also known as cation exchange, ions are displaced by ammonia or heavy metal ions.

Advantages of natural zeolite

  • It reduces a little the acidity of the water.
  • A smaller amount of product is required with respect to silica sand due to its porosity and density.
  • It has a greater surface area and porosity.
  • Produces greater clarity in filtered water.
  • It is the most durable filter media (more than 5 years).
  • It only requires a simple periodic backwash to maintain its efficiency and performance.
  • It has a flow capacity 4 times higher than that of conventional filter media.
  • Increases flow in equipment with multimedia, gravity and pressure systems compared to sand filters.
  • Very few backwash cycles of the zeolite filter are required, resulting in significant energy savings.
  • It has a higher retention capacity due to its larger surface area.

Natural zeolite applications

  • Deep bed zeolite filters.
  • Sediment filters.
  • Industrial filtration.
  • Tertiary wastewater treatment.
  • Water filter for water purification plants, hotels, hospitals, restaurants, Etc.
