Ion exchange for chloride and potassium removal in kraft mills

Optimize your kraft mill operations by efficiently removing corrosive chlorides and potassium from waste streams, reducing costly shutdowns and improving chemical recovery in pulping processes.

Removes Chloride and Potassium from Mill Processes

The PDP™, PRU, and GAP Ion Exchange Systems from Kovalus Separation Solutions are specialized for enhancing Kraft mill operations. These systems efficiently remove chlorides and potassium from production streams, reducing corrosion risks and minimizing unnecessary shutdowns. Utilizing precise ion exchange resins, the equipment recovers valuable chemicals, optimizing both resource use and cost-effectiveness in pulp and paper manufacturing.

Designed for continuous operations, these systems work seamlessly within existing production environments, integrating with other purification processes such as membrane filtration and drying systems. Tailored to handle liquid and slurry products, they feature PLC-controls for sophisticated operations and remote monitoring to facilitate process oversight.

These ion exchange solutions excel in extracting impurities while boosting throughput, particularly in demanding environments like chlorine dioxide generators and electrostatic precipitator dust management. With options for different material compositions, they ensure robust performance against corrosive process conditions, and customizable features address specific plant requirements.

Kovalus offers comprehensive engineering and support services, providing you with the necessary adaptability and technical guidance to maintain compliance and streamline maintenance efforts. Suitable for various industries, from pulp and paper to general industrial applications, these systems are ideal for facilities seeking sustainable and efficient operations.
