Spiral wound

A spiral membrane consists of a series of polymeric sheets wound around a central tube that enables permeate to escape. These membranes are widely used in the food and dairy industries. They are designed to handle minimal suspended solids.

Functional features include:

• low – medium viscosity products
• compact design
• large amount of area per element
• cost effective for high capacity plants
• low capital and energy plants
• low replacement cost
• low permeate pressure needed
• medium life expectancy
