DOW FilmTec Commercial RO Membrane Elements
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. FRP-wrapped elements are recommended for systems with multiple-element housings containing three or more membranes, as they are designed to withstand higher pressure drops.
- DOW FILMTEC TW30 elements are an industry standard for reliable operation and production of high quality water. These features 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.
- DOW FILMTEC HR elements offer high rejection for excellent water quality and reduced downstream polishing.
Benefits
Benefits of DOW FILMTEC Tap and Brackish Water Commercial Elements
- Reverse Osmosis removes up to 99% of total dissolved solids.
- RO membranes remove dissolved impurities such as chloride, lead, chromate, fluoride, bacteria, and others. Click here to view the nominal rejection characteristics of thin film membranes.
- Hard-Shell FRP Wrap allows elements to withstand higher pressure drops, making them ideal for systems with multiple elements per housing
- BW30 elements provide longer life due to increased resistance to fouling and high cleanability.
- LC & LE elements reduce operating costs due to lower energy requirements.
- LE HR high rejection elements produce excellent water quality, reducing the downstream polishing required.
