Before the use of water treatment equipment, we need to deal with it in advance. Most of the water of deionized water treatment equipment contains many impurities. If not treated, water treatment equipment for glass tank membrane cleaning will seriously affect the water treatment effect. We must remove or coat water treatment equipment to reduce impurities. Five points should be paid attention to before using water treatment equipment.

1. First of all, we should sediment the sewage and establish a large sedimentation tank.

2. Using various coagulants, impurities will be generated into large particles of sediment, which will be removed by other equipment.

3. The precipitated water will flow through the device equipped with special filter material to intercept the impurities in the water and remove them.

4. Chemical reagents or cation exchange resin are used to remove calcium, magnesium and iron ions from water.

5. Adding chemicals or using ultraviolet and ozone to eliminate microorganisms and bacteria in water.
