In order to meet the requirement of safe drinking water for people, the most effective method adopted in the current market is to arrange a water purifying device at a user end. According to the difference of the precision of the filtered water, the water purifying equipment can be mainly divided into microfiltration, ultrafiltration, nanofiltration and RO reverse osmosis. Among them, the RO reverse osmosis has the highest filtration accuracy and is therefore selected by most users. In the RO reverse osmosis membrane water purification equipment, raw water enters an RO membrane after being subjected to multi-stage filtration and pressurized by a booster pump, and water filtered by the RO membrane is supplied to a user through a pipeline. Because raw water is filtered by multiple stages, if the flux of water purification equipment is small or the using amount is large, the pure water filtered by the RO membrane has less water amount and can not meet the requirement of water consumption of a user.
