BW Industrial brackish water RO membrane elements are made using the newest materials and production processes. They have a high desalination rate, water yield, chemical durability, and are strongly pollution resistant. This product is suitable for desalination of brackish water with salt content less than 10000ppm, desalination of slightly polluted surface water, recycling of cooling circulation water and other applicable fields. As the elements can work well within a wide pH range (pH 1-13), corresponding with the pH range of a wide variety of cleaning solutions, membrane element contamination can be quickly and effectively resolved.
Product Features
High Salt Rejection: suitable for influent water with high salt content.
Strong fouling resistance: the special pollution resistance coating can ensure efficacy of the element under extreme conditions.
Strong resilience to cleaning: the element can be cleaned repeatedly with either acid or alkali solutions, resulting in a long service life.
