Water Treatment & Filtration

Water-related challenges come in many forms. From the turbidity and ammonium concentration of drinking water, to the filtration efficiency of swimming pools, the water-quality stress in aquaculture, and the maintenance of filter media in aquariums — each environment has different requirements.

Natural clinoptilolite zeolite is evaluated as an ion-exchange, adsorption, and filtration-aid material across these diverse water treatment and filtration environments.

Detailed Application Areas

Drinking Water Filtration

Introduces how zeolite is evaluated as an aid for ammonium and turbidity management in water purification systems. → Drinking Water Filtration

Wastewater Treatment

Outlines its role as an aid material for ammonium reduction and water-quality improvement in industrial and municipal wastewater. → Wastewater Treatment

Pool Filter Media

Explains how zeolite is evaluated as a replacement or supplement to sand filter media in swimming pool filtration systems. → Pool Filter Media

Aquaculture Water Treatment

Outlines its use as an aid material in aquaculture filtration systems for managing ammonia-nitrogen, to which fish and aquatic organisms are sensitive. → Aquaculture Water Treatment

Aquarium Filter Media

Explains how zeolite filter media is evaluated in residential and commercial aquarium filtration systems. → Aquarium Filter Media

Considerations When Applying to Water Treatment & Filtration

In water treatment, zeolite performance is not simply a matter of "just add zeolite." The following items must be reviewed together.

• Target water quality and treatment objective
• Key management parameters such as ammonium, turbidity, and metal ions
• Flow rate and contact time
• Particle size selection (varies with filter bed design)
• Backwash cycle and replacement criteria

The appropriate particle size and operating conditions for each field can be found on the respective detail pages.

KMI natural clinoptilolite zeolite is evaluated as an ion-exchange, adsorption, and filtration-aid material across these diverse water treatment and filtration environments. With its outstanding ion-exchange selectivity for ammonium (NH₄⁺), it is widely used to replace or supplement conventional sand filter media. With a CEC of 1.6–2.0 meq/g, a specific surface area of 40.0 m²/g, and a stable pH range of 3.0–10.0, it can be applied across a wide variety of water-quality environments.

In water treatment, particle size selection directly determines performance. 8×14 mesh (1.4–2.4 mm) coarse grade is mainly evaluated for swimming pool filtration and large-scale filtration systems, 14×40 mesh (0.4–1.4 mm) medium grade for filter bed construction, and 30×50 mesh (0.3–0.6 mm) fine grade for water treatment, aquarium, and aquaculture filtration.
