Description
Technical field
The utility model belong to reverse osmosis purified water system technical field more particularly to a kind of reverse osmosis water purifying plant.
Background technique
Reverse osmosis water purifying plant is with directly carrying out purification processes to Natural Water to purifier capable of direct drinking；Its core
The heart is reverse osmosis membrane in reverse osmosis membrane filter element.Wherein, reverse osmosis membrane, which is that a kind of simulation biological semi-permeable film is manufactured, has certain spy
The artificial semi-permeable membrane of property, is the core component of reverse osmosis technology.Reverse osmosis technology principle is in the effect for being higher than solution osmotic pressure
Under, these substances and water cannot be separated through semi-permeable membrane according to other substances.The membrane aperture of reverse osmosis membrane is very small,
Therefore dissolved salts, colloid, microorganism, the organic matter etc. that can be effectively removed in water.System is good with water quality, energy consumption is low,
Pollution-free, simple process, it is easy to operate the advantages that.
Wherein, big flow is reused in interval in use, working as without bucket reverse osmosis water purifying plant, it may appear that higher TDS
Pure water, the reason is that the characteristic of reverse osmosis membrane, after purifier is shut down, inlet water solenoid valve is closed, and booster pump also stops
It only works, after high concentration ion can penetrate into film before reverse osmosis membrane, with the extension of this time of penetration, pure water is dense after film
Degree also can be increased gradually, and downtime is longer, and pure water TDS is higher after film, and ultimate density reaches anterior-posterior balance.
In addition, total dissolved solidss (English: Total dissolved solids, abridge TDS), also known as soluble solid is total
Amount, measurement unit are mg/litre (mg/L), it shows in 1 liter of water dissolved with how many milligrams of soluble solids.TDS value is higher, indicates
The dissolved matter contained in water is more.Total dissolved solidss refer in water the total amount of whole solutes, including both inorganic matter and organic matter
Content.It is generally available conductivity value and probably understands salt in solution, under normal circumstances, conductivity is higher, and salt is higher, TDS
It is higher.In inorganic matter, in addition to the ingredient for being dissolved into ion like, it is also possible to have molecular inorganic matter.Due in natural water
Contained organic matter and molecular inorganic matter can not generally consider, so general be also known as total dissolution admittedly salt content
Body.
