Ultrafiltration is a variety of membrane filtration in which hydrostatic pressure forces a liquid against a semipermeable
membrane. Ultrafiltration produces much cleaner water than micro filtration or
ceramic filtration. For example, ultrafiltration removes particles of 0.1 µm
(micron) or larger, whereas micro filtration
or ceramic filtration removes particles of 0.5 ~ 2 µm (micron) or larger. Ultrafiltration
is effective at removing trihalo-methane
(carcinogen), smell, color, pesticide, natural organic matter (NOM) which comprises trihalomethane (THM) precursors, bacteria and most viruses.
We currently manufacture two types of ultrafiltration filters, 0.1 micron and 0.01 micron.
Unlike reverse osmosis filter which strips natural minerals that are healthy to human body from the water
and makes the water very acidic, ultrafiltration
membrane retains healthy minerals in water and does not change the pH of
water.
Reverse osmosis is very wasteful that 4 gallons or more are wasted down
the drain for every gallon produced, whereas there is no waste when
water is filtered with ultrafiltration.
