Product Details
The ro membrane BW 8040 is an 8 inch spiral wound reverse osmosis element configured for systems treating water with moderate salinity. It is commonly installed in multi-element pressure vessels where stable output, consistent permeate quality, and long operating cycles are required.
We supply the ro membrane BW 8040 for use in system assembly, equipment manufacturing, and project operation. Under standard test conditions, it delivers a stabilized salt rejection of 99.6%, a minimum rejection of 99.4%, and a permeate flow of 40 m³/d, meeting the performance requirements of high-capacity reverse osmosis systems.
Product Identification and Format
The designation ro membrane BW 8040 follows common industry naming conventions:
BW indicates suitability for brackish water sources
8040 refers to the element size, approximately 8 inches in diameter and 40 inches in length
The structure is based on a spiral wound membrane element, allowing efficient separation within compact pressure vessels
This format ensures compatibility with standard 8 inch housings used in industrial reverse osmosis systems.
