The invention provides a water purifying apparatus and a reverse osmosis water purifying system thereof. The reverse osmosis water purifying system comprises: at least two reverse osmosis filter cores which are connected in parallel; at least two wastewater solenoid valves which are connected with the reverse osmosis filter cores; a pipeline comprising a raw water branch tube, pure water branch tubes and wastewater branch tubes; and a monitoring device capable of monitoring the TDS value of water in the pipeline. When the monitoring value of the monitoring device is less than a preset TDS value, the at least two wastewater solenoid valves are alternately open for a first preset time; when the monitoring value of the monitoring device is greater than the preset TDS value, the at least two wastewater solenoid valves are alternately open for a second preset time; and the first preset time is less than the second preset time. The monitoring device can monitor TDS value of the water, so the performances of the reverse osmosis water purification system are improved; and the open time of the at least two wastewater solenoid valves is controlled by the TDS value of the water in the pipeline, so the water resource is saved, and the service life of the reverse osmosis filter cores is prolonged.
Description
technical field [0001] The invention relates to the technical field of water purification equipment, in particular to a water purification equipment and a reverse osmosis water purification system thereof. Background technique [0002] Reverse osmosis technology is a membrane separation technology that uses pressure difference as the driving force to separate the solvent from the solution. Apply pressure to the solution on one side of the membrane. When the pressure exceeds its osmotic pressure, the solvent will reverse osmosis against the direction of natural permeation, so that the permeated solvent, that is, permeate, will be obtained on the low-pressure side of the membrane; A concentrated solution is a concentrated solution. [0003] The current reverse osmosis system cannot detect the TDS value of the water in the waterway in real time, but only controls the opening and closing of the waste water solenoid valve of the reverse osmosis system according to the timing dev...
