NAQWA, Spring Water Recoverer is intended for advanced drinking water recovery treatment of water from superficial and underground raw water sources as well as from centralized water supply systems. It is an excellent drinking water solution for Rural Water, Emergency situations, Army and Travelling.

NAQWA reduces to zero or to an acceptable rate the concentration in water of the following dangerous contaminants:

  • the most dangerous bacteria,
  • heavy metals,
  • radio nuclides,
  • pesticides,
  • other hazardous substances.

At the same time all important for human health micro elements remain preserved in the purified water.


The track membrane cartridge is the core NAQWA. The track membrane is a thin polymer film of about 10 microns thick on each square centimeter of which there are hundreds of millions of pores (tracks) of 0.2-0.4 microns in diameter (approximately 100 times thinner than a human hair) which ensures the highest quality of water purification. The purification quality remains unchanged and does not reduce its perfectness until the complete expire of NAQWA operating capacity (up to 20 000 litres annually).

NAQWA is a green product and made of materials approved for contact with drinking water. During purification the risk of mixture of the purified and contaminated water is practically excluded due to the special design of NAQWA.

NAQWA is the lightest in its class (its weight is only 95/65 grams with and without casing), portable and very easy in operation. NAQWA requires no power supply and can produce up to 50 litres of safe drinking water per day.
