Membrane module basics
A3’s plate ultrafiltration modules use flat sheet membranes arranged in parallel. Multiple flat sheet membranes are imbedded into a grouting material with a fixed distance of 7 mm (1/4”). The other two sides of the membrane module are PVC plates. The individual flat sheet membranes have a porous supporting structure that is covered with a protecting fleece and a PES (Polyether Sulfone) or PVDF (Polyvinyl-Di-fluoride) membrane on both sides. The treated permeate is collected inside the supporting structure and drawn to an attached permeate pipe and finally discharged. The permeate pipe has a top and bottom for better flow distribution through the membrane module.
