Nano membrane Purification systems for all types of facilities and utilities

  • The NF membrane is accredited by the US R&D 100 Awards in 2015 in the field of water treatment.
  • Eltech group is proud to offer Nano filtration systems, designed to be specifically used as water softeners and filtration systems.
  • Nano filtration is a liquid separation membrane technology positioned between reverse osmosis (RO) and ultrafiltration (UF)
  • A Nano filtration filter has a pore size around 0.001 micron.
  • Nano Membranes provide high productivity performance while reducing a high percentage of salts, nitrate, and organic compounds such as pesticides, herbicides.
  • The low net driving pressure NF membrane allows the removal of these compounds at low operating pressures


NF also removes hardness from water, which accounts for NF membranes sometimes being called “softening membranes”


Filter Stages

Stage 1 (1 Micron sediment filter)

With only 1 micron rating, provides effective filtration to protect your membrane. It provides for improved membrane performance up to 95% of TDS rejection.

Stage 2 (5 Micron filter)

With only five micron rating. It is effective in removing dirt, rust and sand particles.

Stage 3 (Activated Carbon filter)

It takes out 99% of the chlorine and organic chemicals. It provides enhanced reduction of taste, odor, and color.

Stage 4 (NANO membrane)

A thin film composite GE high quality US membrane that processes 50 gallons per day. It removes the following hard water contaminants that may be present in your water: lead, copper, barium, chromium, mercury, sodium, cadmium, fluoride, nitrite, nitrate, and selenium.

Stage 5 (Post Carbon Cartridges Filter)

The cartridge filled with coconut carbon shell carbon for taste & odor removal.

Stage 6 (Alkaline Ph enhancer)
