Recover caustic materials with these nanofiltration systems

| By Chemical Engineering

Causti-COR nanofiltration systems are specifically designed to recover and purify caustic for reuse in food, beverage and industrial applications. The systems can recover up to 95% of caustic from solutions used to clean process equipment inScreen Shot 2017-04-27 at 11.58.29 AM industrial applications, says the manufacturer. Patented spiral-wound filter elements allow purification of up to 20% sodium or potassium hydroxide at solution temperatures up to 70°C (160°F). Six models of Causti-COR systems are available to handle flowrates up to 32 m3/h. There are three batch-mode systems for processing feed flowrates between 1 and 15 m3/h and three continuously operated systems for processing feed flowrates between 4 and 32 m3/h. Custom-engineered systems are available to treat larger or application-specific flowrates. — Koch Membrane Systems, Wichita, Kan.
