Dow Filmtec BW30 PRO-4040 Reverse Osmosis (RO) Membrane (BW30-4040)

2,400 GPD industrial / commercial replacement reverse osmosis (RO) membrane element

Filmtec brackish water reverse osmosis membrane elements provide consistent, outstanding system performance in light industrial applications.

  • Filmtec BW30 PRO-4040 is the industry standard for reliable operation and production of the highest quality water.

Elements with a hard shell exterior are recommended for systems with multiple-element housings containing three or more membranes, as they are designed to withstand higher pressure drops.

Filmtec BW30 PRO-4040 Reverse Osmosis (RO) Membrane

*Permeate flow and salt rejection based on the following test conditions: 2,000 ppm NaCl, applied pressure of 225 psig (15.5 bar), 77F (25C), and 15% recovery. Permeate flows for individual elements may vary +/-20%.

**Under certain conditions, the presence of free chlorine and other oxidizing agents will cause premature membrane failure. Since oxidation damage is not covered under warranty, Dow recommends removing residual free chlorine by pretreatment prior to membrane exposure. Most RO systems have carbon pre-filters for this purpose.

***Maximum temperature for continuous operation above pH 10 is 95F (35C).
