Permionics Nano Filter for Municipal water

NF Membrane is used for less than 500 TDS water only.

Why NF Membrane?

Nanofiltration is a membrane filtration-based method that uses nanometer sized through-pores that pass through the membraneNanofiltration membranes have pore sizes from 1-10 nanometers, smaller than that used in microfiltration and ultrafiltration, but just larger than that in reverse osmosis.

Advantages:

 

  • Lower discharge volumes, lower retentate concentrations than RO for low value salts;
  • Reduction salt content and dissolved matter content (TDS) in brackish water;
  • Reduction in heavy metals;
  • Reduction in nitrates and sulphates;
  • Reduction in colour, tannins and turbidity;
  • Softens hard water when specific softening membranes are used;
  • “chemical-free”, e.g. needs no salt or chemicals during operation;
  • pH of water after nano-filtration is normally non-aggressive;
  • Disinfection.

Disadvantages:

 

  • Higher energy consumption than UF and MF (0.3 to 1 kWh/m³);
  • Pre-treatment is needed for some heavily polluted waters (pre-filtration 0.1 – 20 microns). This is always the case with spiral-wound membranes.
  • Limited retention for salts and univalent ions.
  • Nano-filtration membranes are a little more expensive than reverse osmosis membranes;
  • Membranes are sensitive to free chlorine (life-span of 1000 ppmh). An active carbon filter or a bi-sulphite treatment is recommended for high chlorine concentrations.

Description

Anything in excess is dangerous for one’s health, so are excess dissolved salts in your drinking water. Permionics brings to you multistage water purification systems for removal of excess dissolved salts from drinking water depending upon the feed water TDS levels.

TDS Rejection: 35 to 40%

Less Reject water comparing to RO .

Saves Water

Keeps Essential minerals.

Pureflo NF is yet another pioneering concept from the Pioneers of Membrane Technology in India to prevent indiscriminate use of RO systems on low TDS water such as municipal supply that produces almost distilled water which is dangerous to your health.

“Pureflo NF” – The First Chlorine Resistant Nanofiltration Membrane based water purifier to remove the right amount of TDS from water to give you healthy and nourishing drinking water; ideal for waters having TDS below 600 ppm; also removes pesticides, heavy metals and other harmful organic compounds from water.

Make a decision today to buy the revolutionary Pureflo NF water purifier and ensure that your family drinks healthy and nourishing water. Your family’s health – first and foremost!
