DOW FILMTEC BW30HR-440i
The DOW FILMTEC BW30HR-440i element is a high-performing and productivity element combining the highest active membrane area available in the industry today with maximum rejection brackish water reverse osmosis (RO) membrane. It incorporates Dow’s innovative and proprietary BW30HR membrane sheet technology, designed to deliver the highest quality RO permeate. This is combined with the cleanability of a 28 mil feed spacer, to minimize capital expenses in high-purity industrial water applications, without increasing operating flux.
Advantage:
- Produces 20 percent more water compared to the BW30-400 element, and 10 percent more water compared to the BW30-440i element, at the same operating pressure and with higher rejection, enabling lower capital expense for new systems, or increased water production in an existing system.
- The BW30HR membrane sheet sustains maximum rejection over the useful life of the RO element of critical solutes, including silica, boron, ammoniumand nitrate.
- Includes iLEC™ (interlocking endcaps) technology, which reduce system operating
costs and the risk of o-ring leaks that can cause decreased permeate water quality. - Designed using an industry standard 1.125 inch ID permeate tube for interchangeability with other brackish water elements.
