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. We 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.

Common applications include food and dairy separation, electrocoat paint recovery, brackish water treatment, water softening and organics removal. The sanitary spirals are widely used in dairy, food and pharmaceutical industries for clarification, concentration and purification of valuable ingredients, meeting quality standards without compromising yield. Spiral-wound elements offer the highest packing density and most economical solution of all configurations.
