FILMTEC™ Seawater Reverse Osmosis 8" Elements

FILMTEC™ Seawater Reverse Osmosis 8" Elements can separate salts from water and are designed to reduce capital and operational costs of large desalination systems that produce greater than approximately 10 gpm (2300 L/h) of permeate. With a wide range of membranes available to meet various system design requirements, our RO products combine excellent membrane quality with automated precision fabrication, taking system performance to unprecedented levels.


FILMTEC™ SW30HRLE-370/34i Elements are a durable, high-rejection, high-productivity seawater element for use in high fouling or challenging feedwater conditions, helping to support smooth operations and low cost of water. DOW FILMTEC SW30HRLE-370/34i elements use a 34-mil feed spacer to lessen the impact of fouling on pressure drop across a vessel and enhance cleaning effectiveness and may be cleaned over a wider pH range (1 – 13) than other RO elements. iLEC™ Interlocking End Caps reduce system operating costs and the risk of o-ring leaks that can cause poor water quality.
