How should the reverse osmosis equipment be operated for the first time?

The air in the pipeline will be driven away by low pressure and low flow, only when the air in the pipeline does not exist can the equipment operate normally. First of all, the pressure should be kept between 0.2~0.4MPa. When using low pressure flushing and venting, discharge the resulting thick and produced water into the sewer.

If the pressure rises quickly during operation, this is when the membrane element is filled with air and the water flows with radial impact. This may cause the outer skin of the membrane to rupture, resulting in a non-repairable reverse osmosis membrane.

When using the membrane for the first time, it is important to adjust the membrane operating pressure to 0.2 to 0.4MPa for flushing and to ensure that the reverse osmosis system automatically flushes the membrane at low pressure each time it is started.

How to replace the security filter in the reverse osmosis equipment?

After using the security filter for a period of time, the water quality treated will be different due to the long service life. The replacement of the filter cartridge should be based on the pressure difference between the front and rear of the filter, and should be considered when the pressure difference is greater than 0.03MPa.

Replacement method: Turn off the reverse osmosis system. Remove the pressure and press the button of the pressure relief valve on the equipment until the indication on the pressure gauge is zero. Open the filter bottle of the filter with a professional spanner rotary type. Pull out the old filter cartridge and replace it with a new one. Use a professional spanner to tighten the filter bottle rotatingly.

How to clean and disinfect the reverse osmosis system?

Generally for the reverse osmosis system cleaning requirements of professional technical personnel to carry out, the customer is not able to clean their own, if the reverse osmosis system needs cleaning should contact professional manufacturers to complete. The following conditions are the prerequisites for chemical cleaning, and if they occur, cleaning can be carried out.

The prerequisites for chemical cleaning are: when the water production of the system is 5-10% lower than at the beginning or at the last cleaning operation. If the desalination rate of the system is 2.5-5% lower than at the beginning or at the time of the last cleaning. When the pressure difference between the various sections of the system is 1-2 times that of the initial or previous cleaning. When the system is to be protected by a protective solution during a long-term shutdown.

Note: The water yield and desalination rate will be affected by the water temperature, so the results of the test should be in the case of the same water temperature.
