Desalination equipment users know that in the process of using the equipment, water pressure, temperature and water quality will affect the desalination equipment. If you do not pay attention to these values, it will directly lead to substandard water quality.

The inlet pressure of the desalination equipment itself does not affect the excessive penetration of salt, but the addition of the inlet pressure will increase the net pressure of the anti-penetration, and the output value of the water will also increase. Together, excessive salt penetration simply stays the same. The added water production diluted the salt content through the membrane, reduced the penetration rate of the salt and increased the desalting rate. When the inlet pressure exceeds a certain value, due to the high recovery rate, the addition of concentration polarization will lead to the excessive addition of salt penetration, which will offset the addition of water production, so that the desalting rate will no longer increase.

I. The reason for the high water pressure may be: desalting equipment desalting skills research center

1. The outlet valve of the high pressure pump is not adjusted correctly.

2. The pipeline from the high-pressure pump to the RO is blocked.

3. If the concentrated water regulating valve is closed too tightly or blocked, the concentrated water discharge flow will be small.

4. The recovery rate is low.

2. The reasons for low feed water pressure may be:

1. Feed water flow rate is not appropriate.

2. System leaks.

3. The inlet pressure of the high pressure pump is insufficient or the parts of the pump are leaking or leaking.

4. The filter element of the fine filter is polluted and blocked.

5. The high pressure pump is faulty.
