More membrane surface area in a smaller footprint

| By Mary Page Bailey and Gerald Ondrey

The newest addition to this company’s X-Flow line of membrane elements, the X-Flow XF75 ultrafiltration (UF) element (photo), can be implemented into both new and existing water-treatment projects. Although the outer dimensions are the same as those of existing X-Flow membrane elements with membrane areas of 55 and 64 m2, this company has redesigned the internal workings and used modified materials to create extra membrane surface area. This latest update provides key advantages in terms of surface area in relation to element size. By maintaining the existing element outer dimensions and increasing the total surface area to 75 m2, users can take advantage of more membrane surface area per unit of weight or volume than the average of similar UF technologies available today, says the company. — Pentair plc, London, U.K.
