It sets.
Background technique
Infiltration is a kind of physical phenomenon.Contain the water of different salts when two kinds, is such as separated with a semi-permeable film
It finds that the moisture on one side of low salinity can be seeped into the high water of salt content through film, gradually the salt concentration on both sides
Until being fused to equalization, this process is known as permeating.Take a long time however, to complete this process.But if in saliferous
High water side is measured, a big pressure is applied, direction can be made to permeate to opposite direction, and salinity is remaining, this process is known as reverse osmosis
Thoroughly.Osmosis filtration principle imposes the pressure bigger than naturally osmotic pressure, makes exactly in the water for having impurity (such as raw water)
Infiltration carries out round about, the hydrone pressure in raw water to the another side of film, becomes clean water, to reach removing
The purpose of impurities in water, salinity.
RO film is in use, be easy to be attached in RO film surface and hole because of a large amount of depositions of substance in water, cause RO film
Blocking leads to that water yield becomes smaller and filtering water is not clean.And this deposited phenomenon occurs mainly under water stationary state, stream
Dynamic water flow is not allowed to be also easy to produce depositional phenomenon.RO system at work, because water is in flowing, is actually not easy precipitating knot
Dirt and stifled film problem occurs.And when RO system is in standby, high concentration water in RO film, because of long-time quiescent setting, water
Middle substance (such as calcium ions and magnesium ions) can largely deposit the phenomenon that being attached to RO film surface, resulting in blockage (film is blocked up in fouling), lead to after deposition
Crossing water flow flushing can not reach and rinse out deposition completely, affect the practical effect of RO system.
Currently, it is built-in with the water-strainer or water purifier of reverse osmosis (RO) film, one-side detection water quality, if water quality detection
