Filmtec – LE-440-i Reverse Osmosis Membrane

The FILMTEC LE-440i element is a low-energy element featuring the highest active membrane area in the industry. It enables high productivity and low energy operation, while maintaining high-rejection performance, minimizing operating expense and lowering the total cost of water for industrial and municipal applications.

Delivers the same permeate flow at an equivalent operating flux at 40% lower feed pressure, compared to the FILMTEC BW30-440i element. Offers permeate flow rate 10 percent higher while producing similar permeate quality than that of the FILMTEC LE-400 element, enabling the lowest total cost of water in high-purity industrial applications. Includes iLEC interlocking end caps, which reduce system operating costs and the risk of o-ring leaks that cause poor water quality. Designed using an industry standard 1.125 inch ID permeate tube for interchangeability with other brackish water elements.
