SR 4" Nanofiltration Elements, 4040-SR, Active Membrane Area ft² (m²): 85 (7.9), Koch Membrane Systems (CAT#: STEM-P-0134-LSY)

SR 4" Nanofiltration Elements, Nanofiltration, model 4040-SR is manufactured by Koch Membrane Systems. Our high flow, low pressure and selective rejection nanofiltration membrane elements are specially designed for softening water and removing organic matter, with excellent performance and reliability. The NF series uses less chemicals to easily remove the hardness, while significantly reducing the total organic carbon. The membrane type and material of this product are SR-selective rejection nanofiltration and proprietary TFC^® polyamide chemistry respectively. The element easily removes hardness using fewer chemicals while significantly reducing total organic carbon, it is recognized for its excellent performance and reliability. This product is suitable for separation of higher molecular weight components (>200 Dalton) and multivalent ions from various feed solutions, hardness and sulfate removal from seawater and chloralkali process stream
