AICKSN water purifier: Can the pre-filter purify water?

The principle of reverse osmosis technology is higher than the osmotic pressure of the solution, based on other substances can not pass through the semi-permeable membrane and these substances and water to leave.The membrane pore size of the reverse osmosis membrane is very small, so it can effectively remove dissolved salts, colloids, microorganisms, organic matter, etc. in water.RO system because there is a high-pressure pump, and need to add a special scale inhibitor, high operating costs.How do we reduce the operating costs of the RO system?

In order to make the RO device can be safe and reliable operation, easy to monitor the operation process, should be equipped with the necessary instrumentation and control devices, generally need to install the instrumentation has a temperature meter, flow meter, pressure meter, conductivity meter, oxidation potential meter, chlorine meter, pH meter, specific as follows:

Users reflecting their own purchase of reverse osmosis equipment frequently wash membrane, reverse osmosis membrane use life is short and other issues. Today Susan organized a compilation of reverse osmosis equipment for reference, welcome to exchange, correction.
