详情 Detailed description


(1) Product Positioning

The NTF series membrane elements are nanofiltration membranes specifically developed for industrial water treatment, with key applications in leachate treatment, wastewater decolorization, reduction of high-salinity brine, water softening, and denitrification.

(2) Product Features

Industry-leading water production capacity, with high output even under low-pressure operating conditions.

It exhibits high removal rates for total organic carbon (TOC) and sulfate, while permitting a lower degree of hardness ion passage.

It offers the broadest pH cleaning range and can withstand multiple acid–alkali washes in cases of severe fouling.
