Background

Reverse osmosis (RO for short) is a highly new membrane separation technique using pressure difference as driving force, and has the characteristics of high primary separation degree, no phase change, simplicity and high efficiency, the 'aperture' of the reverse osmosis membrane is as small as nanometer (1nm is 10-9m), and any 'filtering' pores on the surface cannot be seen under a scanning electron microscope. Under the operating pressure higher than the osmotic pressure of the raw water, water molecules can pass through the RO semipermeable membrane in a reverse osmosis mode to produce pure water, and a large amount of inorganic ions, organic matters, colloid, microorganisms, heat sources and the like in the raw water are intercepted by the RO membrane. When the conductivity of raw water is less than 200 mu S/cm, the conductivity of the first-stage RO pure water is less than or equal to 5 mu S/cm, and the standard of laboratory third-stage water use is met. For areas with high raw water conductivity, in order to save the replacement cost of the subsequent mixed bed ion exchange resin and improve the quality of pure water, customers can consider selecting a secondary reverse osmosis purification system, and the conductivity of the secondary RO pure water is about 1-5 mu S/cm and is related to the quality of the raw water. The principle function of reverse osmosis: the method is characterized in that dilute solution (such as fresh water) and concentrated solution (such as seawater or saline water) with the same volume are respectively arranged at two sides of a container, the middle part of the container is blocked by a semipermeable membrane, a solvent in the dilute solution naturally penetrates through the semipermeable membrane and flows towards the concentrated solution side, the liquid level at the concentrated solution side is higher than that of the dilute solution by a certain height to form a pressure difference, an osmotic equilibrium state is achieved, the pressure difference is osmotic pressure, the magnitude of the osmotic pressure is determined by the type of the concentrated solution, and the concentration and the temperature are independent of the property of the semipermeable membrane. If a pressure greater than the osmotic pressure is applied to the concentrate side, the solvent in the concentrate flows toward the dilute solution in a direction opposite to that of the original permeate, a process known as reverse osmosis.

But when preparing at reverse osmosis pure water, should equipment use for a long time, cause equipment ageing to when producing the quality of water that does not conform to the requirement, often should can't detect quality of water purity in advance, unmanned on duty, unable early warning in advance causes the unqualified pure water of output to get into the water area, to above-mentioned problem, provides an equipment detecting system of thing networking intelligent management technique.
