FILMTEC SW30HR LE-4040

FILMTEC™ SW30HR LE-4040 is a four-inch diameter version of SW30HR LE-400, the industry's leading seawater element which offers an unprecedented combination of high salt rejection and productivity to enable the lowest total cost of purifying high salinity water.

  • SW30HR LE-4040 may be used as a pilot element to demonstrate performance for the design of larger systems.
  • SW30HR LE-4040 delivers the highest sodium chloride and boron rejection to help meet World Health Organization (WHO) and other drinking water standards.
  • SW30HR LE-4040 elements deliver high performance over the operating lifetime without the use of oxidative post-treatements like many competitive products. This is one reason FILMTEC elements are more durable and may be cleaned more effectively over a wider pH range (1 - 13) than other RO elements.
