Clack Garnet: High-Density Filter Media for Superior Multi-Media Filtration

Clack Garnet Filter Media is specifically designed to address the challenges of single media filtration systems by providing a solution through multi-media or mixed media filtration. This high-density, small-grain filter media is ideal for achieving superior filtration performance, particularly in systems that require a stable, layered bed for optimal water treatment.

Key Features: Advanced Multi-Media Filtration

• High-Density Filtration: Garnet's specific gravity of 4.0 allows it to form the lower fine-grain layer in multi-media filtration systems, providing effective filtration down to the 10-20 micron range.
• Enhanced Filtration Performance: When combined with other filter media like sand and anthracite, Clack Garnet enables higher flow rates, greater loading capacity, and better filtration results.
• Stable Layering: The unique density and grain size of Garnet ensure that the filter bed maintains its grading, with large grains on top and smaller grains at the bottom, even after repeated backwashing.
• Durable and Long-Lasting: With a hardness of 7.0-7.5 on the Mohs scale, Clack Garnet is highly resistant to attrition, providing years of reliable service.
• Versatile Applications: Suitable for both water and wastewater treatment, with customizable filter bed configurations to meet specific needs.
• AWWA B100-96 Compliance: Meets stringent industry standards for water treatment.

Advantages of Using Clack Garnet

• Optimized Filtration Design: The high specific gravity of Garnet allows for the creation of uniquely designed filter systems that maintain their effectiveness over time.
• Improved Filtration Efficiency: When used in combination with other filter medias, Clack Garnet enhances the overall filtration process, allowing for higher flow rates and improved sediment capture.
• Long-Term Durability: The high hardness of Garnet ensures minimal attrition, providing long-term, reliable performance.
• Wide Applicability: Ideal for municipal and industrial water supply applications, as well as wastewater treatment.

Ideal Applications

• Municipal Water Treatment Plants: Enhances the performance of multi-media filters, providing superior water clarity.
• Industrial Filtration Systems: Suitable for demanding filtration processes that require high durability and effective sediment removal.
• Wastewater Treatment: Efficiently captures fine particles, making it ideal for complex filtration needs in wastewater treatment.
• To determine if your media filter backwash rate is adequate consider installing our device. Incorrect filter backwash rates can cause filter plugging (too low) or media loss (too high).
