A method for preparing a spiral wound filtration module is provided. The module has a central permeate carrier tube. The method includes winding at least one filtration leaf about the permeate carrier tube. The filtration leaf includes a first membrane sheet, a permeate carrier sheet, and a second membrane sheet. The winding step creates an end face extending radially outwardly from the permeate tube on each end thereof. After winding, the filtration module is maintained in a wound state. An adhesive is then supplied to each end face and a vacuum is applied through each of the permeate tube. While the vacuum is applied, the permeate tube and filtration leaf assembly are spun in a centrifuge until the adhesive has solidified. After spinning, each end face of the module is severed at a distance between the level of adhesive along the feed spacer screen and the level of adhesive along the permeate carrier sheet.
