Tap Water Commercial DuPont
DOW FILMTEC offers a variety of low energy and high rejection FILMTEC reverse osmosis elements for small commercial operations such as car washes and resort applications.
- DOW FILMTEC TW30 elements are an industry standard for reliable operation and production of high quality water. These feature a 34 mil feed spacer to lessen the impact of fouling and may be cleaned over a wide pH range (pH 1-13) for the most effective cleaning.
- DOW FILMTEC LP & XLE elements deliver high performance at low pressure resulting in less energy usage and lower costs.
