OriginWater, a Chinese company in water purification, recently announced the nanometer filtration technique, the fourth generation of water purifying technology.

The technique increases the efficiency of water purification. Earlier techniques took three glasses of waste water to produce one glass of purified water. The technique is based on the ultra low pressure nanometer filter membrane, which can filter particles with a diameter of more than one nanometer.

In addition, the technique solves the problem of filtering harmful materials and beneficial microelements. The nanometer filtration technique not only filters bacteria, colloids, and heavy metals, but also leaves beneficial mineral elements in the purified water. Different from traditional purifying techniques, the nanometer filtration technique satisfies the needs of both safety and health.
