Reverse osmosis equipment has become the most used water treatment equipment in the industrial production process because of its good water purification effect. During the use of reverse osmosis equipment, some users inevitably encounter some small problems, which may seem small but may easily lead to the obstruction of equipment operation. Let me tell you some precautions when using reverse osmosis equipment so that you can avoid mistakes during use.

1, the total amount of reverse osmosis equipment into the water (that is, the sum of the water and concentrated water) by RO water control valve to control, if the reverse osmosis equipment into the water does not change, do not move RO water control valve, fully open or fully closed is strictly prohibited; RO concentrated discharge regulating valve used to adjust the system recovery rate, such as the recovery rate does not change, do not move the concentrated discharge regulating valve, absolutely prohibit full open or full closed.

2. When the high and low-pressure alarm occurs in the reverse osmosis equipment, first check whether the opening of the manual valve from the security filter to the high-pressure pump is too small, then check whether the RO water inlet regulating valve and the concentrated discharge valve is normal, and then press the reset button of the high and low-pressure alarm to restart the equipment.

3, the operation of pressure control, under the premise of meeting the water production and water quality, takes the lowest pressure value as far as possible, which is conducive to reducing the water flux attenuation of the membrane, reduce the membrane replacement rate.

4. Inlet water temperature control, according to the actual water consumption, should take the critical pressure (inlet water pressure is lower than the value of desalination rate resulting in a significant decrease of pressure value) cannot meet the requirements of the river and water quality as the lowest temperature, to reduce the attenuation of membrane water.

5. Emission control. Due to the change of water temperature, operating pressure, and other factors, the amount of water produced by the device also changes accordingly.

The above points are the points for attention in the use of reverse osmosis equipment. Master, this knowledge can reduce equipment failures and ensure the quality of water production.
