Dow Filmtec Membrane BW30-400i

The FILMTECTM BW30-440i element is a high-productivity element combining the highest active membrane area in the industry with the high rejection BW30 membrane. It is designed to minimize capital expenses in high-purity industrial water applications without increasing operating flux.

Produces 10% more water compared to the FILMTEC BW30-400 element at the same operating pressure and high rejection, enabling lower capital expense for new systems, or increased water production in an existing system. Includes iLEC™ interlocking endcaps, which reduce system operating costs and the risk of o-ring leaks that can cause poor water quality.

Designed using an industry standard 1.125 inch ID permeate tube for interchangeability with other brackish water elements.
