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
