1. Raw wastewater flushing Solenoid valve It was changed into a special pressure relief frequency conversion flow limiting valve of Hamilton to ensure the pressure stability of the reverse osmosis system.
2. The waste water return pressure stabilizing solenoid valve is added to ensure the waste water return ratio and return pressure. At the same time, the waste water sedimentation separation return is carried out.
3. The pressure drum return solenoid valve is added to ensure the automatic adjustment and control of the clean water washing membrane.
4. The return air pressure and flow probes are added to ensure the data collection and command release of the control system.
5. Customized 4-point interval startup HV switch To prevent waste of water resources due to frequent machine startup. Water production can be started only when the water level of the pressure drum is lower than one third.
6. The microcomputer control panel is independently developed, and the waste water ratio, flushing time, membrane cleaning flow of purified water, and reflux flow of purified water are manually adjusted according to the hardness of the water source. As clean as the raw water is, there will be as much waste water. Realizing measures based on water conditions and rational utilization of water resources.
