RO anti-filter device
Reverse osmosis is to use enough pressure to separate solvent from
solution (usually using water) through reverse osmosis membrane (or
semi-osmosis membrane), so it is named reverse osmosis. As a kind of
high-efficiency desalination technology, the reverse osmosis technology
can get rid of inorganic ion, bacillus, virus, organic substance and
colloid in original water to get high-quality pure water. According to
different materials’ osmotic pressure, using the reverse osmosis method
larger than osmotic pressure can reach to the objective of separation,
extraction, purification and concentration.
The technology of reverse osmosis has many advantages while traditional water treatment methods don’t have:
1. Reverse osmosis is to apply physical method of no phase-transition
for desalination, purification in room temperature. Presently, the
desalination rate of ultra thin composite membrane may be over 99.5％.
Besides, it can also remove colloid, organic substance, bacillus and
virus in water.
2. Water treatment takes hydraulic pressure as the impetus. Its energy consumption is the lowest among many methods.
3. It needn’t using any chemical medicament, acid or alkali to process, so there isn’t nay waste liquid, acid or alkali.
4.The reverse osmosis device can purify water continuously. The system
is simple. It is convenient to operate and water quality is stable.
5. Working maintenance and equipment maintenance is little.
6.This equipment occupies small area.
It is suitable for processing large range of water, not only for salt
water, sea water or even sewage, but also for the processing of fresh
