1. General Introduction
FilmTec BW30-400 Element is a 8 inch type membrane with active filter area 400 square feet for reverse osmosis process, the treated flow rate is 40m3/d(10,500gpd) under standard test condition. BW30-400 increases water production not by increasing membrane flow and increasing operating pressure but by increasing membrane area, so it can maintain a very low fouling rate, thereby maintaining long-term high water production and extending the life of membrane elements. At the same time, its operating pressure is low, which improves the economy of system operation. The high effective area of BW30-400 enables the newly designed RO system to use fewer originals, thereby making the system compact and saving installation costs.
