Technologies

Fujifilm’s development of membranes is continuously on the move. We aim to produce top quality ion exchange membranes that may suit a variety of applications and industries. We focus on high volume supply of ion exchange membranes which enable breakthrough membrane processes to become technically feasible. For this we work together with related customers in various industries such as drinking water, wastewater, food, pharmaceutical etc., to move the industry forward.

Fujifilm membranes can be used in several electro separation technologies (Electrodialysis, Electrodialysis Reversal etc). As each technology has its own focus area and requirements Fujifilm developed a membrane portfolio to suit its customers needs ranging from low electrical resistance membranes to low water permeating membranes with durability in wide pH range.  Our thin homogeneous anion and cation exchange membranes are based on new innovative polymer technology.
