Home / Products / Reverse Osmosis Membrane Elements / Brackish Water (BW) / BWRO Membrane Extra Fouling Resistance Series BW-8040-400XFR/34
BW RO membrane elements are mainly used for brackish water desalination. They provide excellent, stable and consistent membrane performance for industrial water treatment systems.
Product Description
UltraClean XFR series reverse osmosis membranes are manufactured by optimizing the formula, reaction conditions and post-treatment, the membrane skin layer is denser and more hydrophilic, the membrane surface is smoother, the membrane element structure is optimized, and the membrane products are produced with high-quality materials. Effectively purify raw water prone to biological pollution and organic pollution. UltraClean XFR series originals all use the latest diaphragm preparation technology, making their resistance to organic contamination and cleanability up to the industry standard, providing membrane elements with excellent anti-pollution ability and super durability for the difficult water treatment industry. The UltraClean XFR series is available in 8-inch and 4-inch sizes for systems with poor inlet water quality.
Membrane Features
Advanced membrane technology with innovative thin layer composite membrane design.
More consistent performance with less fouling requiring less frequent cleaning and change-outs.
100% dry-stored membrane maximizing shelf life.
