Reverse
Osmosis technology is the most advanced and economical
membrane separation technology. Solvent in liquor can
be separated with help of enough pressure, and the direction
is negative from osmosis direction. This method can be
used to separate, purity and condensate liquor. The use
of reverse osmosis technology can effectively remove the
dissolved salt, colloid, bacteria, viruse, toxins and
most of the organic impurities, and so on.
Because the
diameter of reverse osmosis membrane is very short (about
10 Angstroms), salt, colloid, bacteria, heavy metal ion,
organic compound , viruses and bacillus can be removed,
and we can get high quality pure water.

Reverse
Osmosis membrane is a pressure-driven selective semi-permeable
membrane. Reverse osmosis membrane can remove inorganic,
organic matter, suspended solids, bacteria, colloidal.
The
main performance parameters are water flux, desaltnaton
rate, the effective membrane area, operating pressure,
the recovery rate, temperature and so on.
Reverse
osmosis membrane is built up by cartridge column, water
inlet net, water outlet network, shell, complex film.
The diameter of filtration is 0.0001 micron, so all chemical
ion, bacteria and viruses cannot go through, but only
water molecule. This is how it can purify water. |
