Top 12 common problems with pure water equipment

Pure water equipment Main 12 common problems

Pure water equipment Mainly the following 12 major common problems:

1.Reasons for low water supply pressure may be:

（ 1）Inappropriate water flow rate；

（ 2）System leakage；

（ 3）Insufficient water pressure at the high-pressure pump inlet or water/air leakage in the pump；

（ 4）Clogging of the precision filter element；

（ 5）High-pressure pump malfunction.

2.Reasons for high water supply pressure may be:

（ 1）Improper adjustment of the high-pressure pump outlet valve；

（ 2）Blockage of the pipeline from the high-pressure pump to the reverse osmosis unit；

（ 3）The concentrate valve is closed too tightly or blocked, and the concentrate discharge flow rate is low；

（ 4）Recovery rate is too low.

3.Reasons for low recovery rate may be:

（ 1）Excessive water flow rate；

（ 2）Low water supply pressure or concentration.

4.Reasons for high recovery rate may be:

（ 1）Excessive water supply pressure；

（ 2）Insufficient water flow rate；

5. Pure water equipment Reasons for high pressure drop at both ends may be:

（ 1）High concentrate flow rate；

（ 2）Membrane element contamination；

6.Reasons for high-pressure pump stopping may be:

（ 1）Excessive pump discharge pressure (greater than 1.7MPa ）；

（ 2）Excessive pump inlet water pressure (less than 0.05MPa ）。

7.Reasons for reduced pure water production may be:

（ 1）Low water supply temperature；

（ 2）Low water supply pressure；

（ 3）High concentrate concentration causing high osmotic pressure；

（ 4）Membrane fouling.

8.Reasons for increased pure water production may be:

（ 1）High water supply pressure；

（ 2）High water supply temperature.

9.Reasons for simultaneous increase in pure water conductivity and concentrate conductivity may be:

（ 1）Clogging of the concentrate pipe or concentrate regulating valve；

（ 2）Excessive recovery rate.

10.If the conductivity of the produced water is high, the conductivity of the concentrate is also high, and the pressure drop in each section is also high.

Reason analysis: Membrane element contamination affects the concentrate flow rate.

11.High pure water conductivity, increased container pressure drop, low pure water flow rate

Reason analysis: Membrane element contamination

12.Large container pressure drop, low pure water flow rate but increased conductivity

Reason analysis: Membrane element channel contamination or blockage
