Clack Birm: Efficient Iron and Manganese Removal Media

Clack Birm is a highly effective and economical media designed for the reduction of dissolved iron and manganese from raw water supplies. It functions as an insoluble catalyst, enhancing the reaction between dissolved oxygen and iron compounds, making it easier to filter out iron and manganese from groundwater. Suitable for use in both gravity-fed and pressurized water treatment systems, Birm offers a long-lasting and maintenance-friendly solution for improving water quality.

Key Features: Cost-Effective Water Treatment

• Catalyst for Oxidation: Birm acts as an insoluble catalyst, facilitating the oxidation of dissolved iron (Fe++) to ferric hydroxide (Fe+++), which precipitates and can be easily filtered out.
• No Chemical Regeneration Needed: Under the right conditions, Birm does not require chemical regeneration, reducing ongoing maintenance costs.
• Durable and Long-Lasting: This robust media has a long lifespan and operates effectively across a wide temperature range.
• Efficient Iron Removal: Provides high efficiency in removing iron and manganese, ensuring cleaner water.
• Easy Maintenance: Requires only periodic backwashing to remove accumulated precipitates.
• NSF/ANSI Standard 61 Certified: Ensures that the media meets stringent standards for safety and performance in drinking water applications.
