Research on energy efficiency in current reverse osmosis (RO) membranes showed that configurational energy and element design could improve efficiency, says the company. Filmtec ECO elements combine membrane chemistry and low dP feed spacers to provide lower energy costs and reduce chemical consumption when RO is followed by a mixed bed ion exchange unit.
