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™ SW30XHR-440i Elements are the highest rejection seawater RO element in the  FILMTEC element portfolio, enabling stringent water quality requirements to be met reliably with single-pass seawater systems in most situations. In addition, the combination of high active area and thick feed spacer results in higher productivity and lower cleaning frequency, which enable sustainable lower lifecycle cost. iLEC™ Interlocking End Caps reduce system operating costs and the risk of o-ring leaks that can cause poor water quality.
