The total inflow volume of water to the reverse osmosis system (i.e., the sum of the product water and concentrated water) is controlled by the RO inlet control valve. If there is no change in the inflow volume to the reverse osmosis system, do not adjust the RO inlet control valve arbitrarily; it is strictly prohibited to turn it fully open or fully closed. The RO concentrated water discharge control valve is used to adjust the system’s recovery rate. If there is no change in the recovery rate, do not adjust this valve either; it is absolutely forbidden to turn it fully open or fully closed. 2. When a high/low pressure alarm occurs in the reverse osmosis system, first check whether the opening degree of the manual valve between the safety filter and the high-pressure pump is too small; then check whether the RO feed water control valve and the concentrate discharge valve are functioning properly. After that, press the high/low pressure alarm reset button to restart the equipment. 3. Strictly control the quality of the incoming water to ensure that the device operates under water conditions that meet the specified requirements. 4. For operating pressure control, the lowest possible pressure value should be selected as long as it meets the requirements regarding water production volume and quality; this helps to reduce the decline in the membrane’s water flux and decreases the frequency of membrane replacement. 5. For the control of inlet water temperature, the minimum temperature that can still meet the requirements regarding the volume of produced water and water quality should be used as the inlet water temperature for that period. This temperature is determined based on the actual water consumption and the critical pressure – the pressure level below which the desalination efficiency drops significantly. By using this temperature, the decline in the membrane’s performance can be reduced. 6. Emission control: Changes in factors such as water temperature and operating pressure cause corresponding changes in the water production volume of the device; in such cases, the emissions must be adjusted, otherwise it will affect the desalination efficiency of the device.
