first, the original TDS 300 is set by the controller to determine high TDS water, low TDS water below TDS 100, and medium TDS water between TDSs 100-300. This determination range is a case value, not a constant value. Meanwhile, the three waste water electromagnetic valves 11 are determined to be in a high-low gear, each electromagnetic valve is opened to be in a waste water flow maximum state, and is closed to be in a flow minimum state, and the flow of the combined waste water valve can be in a multi-gear state through the on-off of the waste water electromagnetic valves 11.
Then the following control is performed by the controller:
when the TDS of raw water is more than 300, the three waste water electromagnetic valves 11 are controlled to be in a minimum flow state in a combined way, so that the TDS of the discharged water is ensured to be in a set range;
when the TDS of raw water is less than 100; the three waste water electromagnetic valves 11 are controlled to be in a maximum flow state in a combined way, and the water outlet TDS is controlled to be in a set range;
when the raw water TDS is in 100-300, the waste water flow is reasonably set through the on-off of the three waste water electromagnetic valves 11, so that the RO membrane 2 is in the most reasonable use state.
