KOCH Ultrafiltration Membrane Series


Filtration Solutions for the Industrial and Municipal Markets

KOCH membrane separation technologies are used to concentrate, clarify and purify liquids, and recapture valued materials across diverse industries to increase yield and reduce waste.

Whether you are purifying water or wastewater for reuse, discharge or potable purposes on the front and back end of your operations, we customize advanced filtration systems to help you achieve environmental sustainability.

COCH Tubular

Tubular Membranes

KOCH tubular modules are designed for applications with extreme levels of suspended solids and can concentrate up to 60% solids. Tubular designs have more moderate membrane areas, but larger modules have been developed to accommodate greater feed volumes.

COCH Hollow Fiber

Hollow-Fiber Membranes

There are over 125 different products in our hollow-fiber line, made for applications with a moderate level of suspended solids. Our Hollow-Fiber membranes include pressurized and submerged products, operating in Inside-Out or Outside-In direction.

COCH Spiral

Spiral Membranes

Spiral-wound elements are used in applications that have relatively low suspended solids. A variety of feed spacers of different thickness and geometry are used to expand the solids’ tolerance of spiral elements. KOCH offer more than 200 spiral-wound membranes in a complete range of pore sizes (reverse osmosis, nanofiltration, ultrafiltration and microfiltration). Specific membrane selection is made based on the required separation properties.
