Environmental Remediation & Adsorption

There is one clear reason zeolite draws attention in environmental applications: its adsorption and ion-exchange properties are well matched to substances that need to be removed or have their mobility reduced, such as ammonia, heavy metals, odor-causing compounds, oil, and harmful ions.

This section outlines the key sub-applications where zeolite is considered in environmental remediation and adsorption.

Sub-Application Areas

Ammonia Removal

Introduces the principles and application criteria for use as a supporting material for ammonium ion management in water treatment, wastewater, livestock, and aquaculture environments. → Ammonia Removal

Heavy Metal Removal

Describes its role as a supporting material for adsorption and ion exchange in industrial wastewater, contaminated water, and soil leachate containing metal ions such as lead, copper, and cadmium. → Heavy Metal Removal

Odor & VOC Control

Explains the role of zeolite as a supporting material for managing odors and volatile compounds in indoor spaces, barns, workplaces, and storage areas. → Odor & VOC Control

Chemical & Oil Spill Cleanup

Describes its use as a supporting material for containing spread and aiding adsorption during oil and liquid chemical spills at workplaces, warehouses, and outdoor sites. → Chemical & Oil Spill Cleanup

Wastewater & Biogas Processes

Explains how it is considered as a supporting material for ammonium reduction and process stabilization in high-nitrogen wastewater, anaerobic digestion, and biogas plants. → Wastewater & Biogas Processes

Waste Stabilization & Encapsulation

Describes its role as a stabilization aid for reducing the mobility and leaching of metal-bearing sludge, contaminated soil, and industrial by-products. → Waste Stabilization & Encapsulation

Common Considerations When Applying to Environmental Remediation

Zeolite is a useful supporting material in environmental remediation, but actual performance varies depending on the following conditions.

• Type and concentration of the target substance
• pH and temperature
• Contact time and flow rate
• Presence of competing ions
• Whether it is standalone treatment or part of a combined process

It is advisable to first review the particle size and material property data suited to your application purpose and, where possible, to conduct a small-scale trial application before proceeding to full deployment.

Environmental Remediation & Adsorption

The reason zeolite draws attention in environmental applications is clear: its adsorption and ion-exchange properties are well matched to substances that need to be removed or have their mobility reduced, such as ammonia, heavy metals, odor-causing compounds, oil, and harmful ions.

KMI natural clinoptilolite has a cation exchange capacity (CEC) of 1.6–2.0 meq/g and offers outstanding ion-exchange selectivity, particularly for ammonium (NH₄⁺). It can also adsorb heavy metal cations such as Pb²⁺, Cu²⁺, Cd²⁺, Zn²⁺, and Ni²⁺, and is used to assist VOC adsorption, moisture management, oil adsorption and spread containment, and ammonium reduction in biogas processes. It functions stably across a pH range of 3.0–10.0, and its microporous structure with a specific surface area of 40.0 m²/g is the key to its adsorption performance.

In environmental remediation, the most commonly considered grades are 30×50 mesh (0.3–0.6 mm) fine particles for filtration and water-treatment adsorption, 14×40 mesh (0.4–1.4 mm) medium particles for filter beds, and 100 mesh and finer (<150 μm) powder for mixing and blending processes.

Sub-Application Areas

Ammonia Removal

Introduces the principles and application criteria for use as a supporting material for ammonium ion (NH₄⁺) management in water treatment, wastewater, livestock, and aquaculture environments. The selective NH₄⁺ ion exchange of clinoptilolite is the core mechanism. → Ammonia Removal

Heavy Metal Removal

Describes its role as a supporting material for adsorption and ion exchange in industrial wastewater, contaminated water, and soil leachate containing metal ions such as lead (Pb²⁺), copper (Cu²⁺), cadmium (Cd²⁺), zinc (Zn²⁺), and nickel (Ni²⁺). → Heavy Metal Removal

Odor & VOC Control

Explains the role of zeolite as a supporting material for managing odors and volatile organic compounds (VOCs) in indoor spaces, barns, workplaces, and storage areas. → Odor & VOC Control

Chemical & Oil Spill Cleanup

Describes its use as a supporting material for containing spread and aiding adsorption during oil and liquid chemical spills at workplaces, warehouses, and outdoor sites. Its lightweight nature, with a bulk density of 720–865 kg/m³, is advantageous for on-site handling. → Chemical & Oil Spill Cleanup

• pH and temperature (stable range: pH 3.0–10.0)
• Contact time and flow rate

• Selected particle size and packing method

It is advisable to first review the particle size and material property data suited to your application purpose and, where possible, to conduct a small-scale trial application before proceeding to full deployment. Technical data is available in the TDS and MSDS, and specifications by particle size can be found in the Mesh Size Chart. If you need a sample for field testing, please use the Sample Request.
