Membrane SWRO 4 "Filmtec SW30HR LE-4040

Specification of Membrane SWRO 4 "Filmtec SW30HR LE-4040

FILMTEC™ SW30HR LE-4040 reverse osmosis element 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-treatments 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.
