what is the reverse osmosis？
Reverse osmosis membrane (RO) pure water machine for a systematic explanation. Reverse osmosis membrane filtration accuracy is 0.0001 micron, can filter more than 97% of the impurities in tap water, common household pure water machine generally use reverse osmosis membrane.
What is reverse osmosis membrane
Reverse osmosis membrane is the core element of pure water machine. The principle is that under the action of higher osmotic pressure than the solution, other substances can not pass through the semi-permeable membrane and these substances and water will leave. Reverse osmosis membrane can intercept material greater than 0.0001 micron, is one of the most fine membrane separation products, it can effectively intercept all dissolved salts and molecular weight of organic matter greater than 100, while allowing water molecules through. Therefore, it can effectively remove dissolved impurities from water.
Reverse osmosis membrane has the following characteristics:
1. with high desalting rate;
2. High mechanical strength and service life;
3. can play the function under low operating pressure;
4. It can be affected by chemical or biochemical action.
The effect of reverse osmosis membrane filtration can be measured in-tuitively with TDS pen.
We use a TDS test pen to measure and compare the content of dissolved total solids in tap water and purified water by a pure water machine. The unit is PPM(mg/L), which indicates how many milligrams of dissolved total solids are dissolved in 1 liter of water.
Let's see what the results are.
The smaller the TDS value indicates that the total solids in water are less, by comparison, it is obvious that the TDS value of tap water is 217PPM, and after the purification of household pure water machine after purifying water its TDS value is 8PPM, impurity filtration rate is as high as 97%, visible, the water purified by water purifier is very pure.
Service life of reverse osmosis membrane
The service life of the membrane depends on the chemical stability of the membrane, the physical stability of the component and the turbidity of the tap water. Generally, the life of the reverse osmosis membrane is one to two years for the filtration of municipal tap water. The life of RO film and daily maintenance also has a great relationship, especially the washing function of water purifier can effectively extend the service life of RO film.
The use of household pure water machine
Household pure water machine is suitable for high water purity requirements of home users, it is the best product to solve the family direct drinking water. Tap water purified by a pure water machine can be used as a direct drink. It is a new way of drinking water to replace boiled water, bottled water and bottled water.
