Abstract

The present invention relates to a method of producing a spirally wound filtration module for filtrating a fluid feed into a retentate portion and a permeate portion. The method comprises the step of stacking membrane filtration assemblies and permeate transfer layers on top of each other where each membrane filtration assembly being located between two permeate transfer layers starting with a first permeate transfer layer and ending with a final permeate transfer layer. The leading edges of the membrane filtration assemblies are facing the permeate tube and being sequentially offset. The final permeate transfer layer covers all the leading edges of the membrane filtration assemblies. The method comprises the step of rolling the membrane filtration assemblies and the permeate transfer layers around the permeate tube forming the filtration module.
