In order to avoid the pure water equipment in the use of the problem should do what is right?

Water purification equipment will appear in the use of the problem
Pure water equipment, simply put, is the production of pure water equipment, through the reverse osmosis system of membrane filtration process, filtration of calcium ions, magnesium ions, sodium ions, etc. in the raw water, so that it is excluded with the wastewater, theoretically making the water contains only water molecules. The development of modern society, living and drinking and industrial production of water quality requirements are becoming higher and higher, making it widely used in various fields: living and drinking, chemical industry, medical care, breeding, planting, food, beverage and so on.

Pure water equipment in the use of the following problems and need to be solved even if:
1. When the injected amount of sodium hypochlorite is insufficient and the free chlorine in the feed water cannot be measured, there will be slime on the membrane module of the pure water equipment, and the differential pressure of the pure water equipment will increase. However, for composite and polyamide membranes, the amount of free chlorine entering the membrane module must be strictly controlled, and exceeding the specified value will lead to oxidative decomposition of the membrane.

2. If the SDI5 value exceeds the standard water supply pure water equipment as feed water, the surface of the membrane module will be attached to the dirt, which must be cleaned to remove the dirt.

3. Excessive feed water flow will make the membrane module deteriorate in advance, so the feed water flow should not exceed the design standard value, in addition to concentrated water flow should be avoided as much as possible to be less than the design standard value, in the concentrated water flow is too small under the condition of operation, it will make the pure water equipment in the pressure vessel to happen uneven flow and due to excessive concentration of the precipitation of fouling on the membrane module.
4. Pure water equipment, even if the high-pressure pump has a very short period of time to interrupt the operation of the device may fail.
5. Pure water equipment inlet pressure to maintain an appropriate margin.
6. In order to prevent membrane fouling, pure water equipment start and stop the application of low-pressure water supply to replace the water in the pure water equipment.
7. Pay attention to the differential pressure of the precision filter. The reason for the sharp rise in pressure difference is mainly due to the leakage of turbidity in the precision filter. On the contrary, the reason for the sharp drop in differential pressure is the breakage of the precision filter element and the loosening of the fastening screws of the precision filter element.
8. When the pressure difference between the inlet and outlet of the pure water equipment exceeds the standard, it means that the membrane surface has been contaminated or the water supply flow is above the design value. If the flow adjustment can not solve the problem of differential pressure, the membrane should be cleaned.
9. In the summer water temperature is high, the flow of water production is more, sometimes have to reduce the operating pressure, which will lead to a decline in the quality of water production. To prevent this, the number of membrane modules can be reduced, while the operating pressure is still maintained at a high level.0
