KeenSen Residential NF1 Series: Residential Nanofiltration Membrane Elements
Product Specification and Parameter KeenSen NF1 Nanofiltration membrane elements are rolled by aromatic polyamide compound membrane sheet with US technology. It has the selective desalination mechanism for removal of high polyvalent ions and partial maintaining of monovalent ions with health benefits. Moreover, it can achieve high rejection and ultra-low operating pressure for desalination of raw water with low salt concentration. It can be widely applied to various small sized home water purifying device.

Above parameters are based on below test condition:
Concentration of Solution
Temperature
pH Value
Recovery Rate
250ppm (Tap Water)
25 ℃
6.5-7
15%
The above permeate flow is a average value. The permeate flow of single membrane elements are within a tolerance not exceeding 15% of the average value.
The rejection rate of NF1 series membrane element will be greatly affected by the raw water quality and recovery rate. It is mainly used for removal of high polyvalent irons like calcium, magnesium and heavy metal in raw water.
