Abstract
This application discloses a water system capable of realizing forward and backwashing of an ultrafiltration membrane plus pure water rinsing of an RO membrane, relating to the field of water purification treatment. It includes a pressure tank and a water production pipeline. The surface of the water production pipeline is equipped with a filter element assembly for water filtration, comprising a PP cotton filter element, an activated carbon composite filter element, an ultrafiltration membrane filter element, and an RO membrane filter element. The surface of the water production pipeline is equipped with a flow meter one for monitoring the backwashing water flow rate of the ultrafiltration membrane filter element and a flow meter two for monitoring the water production flow rate during normal water production. The surface of the water production pipeline is also equipped with a detection component for detecting the pressure values before and after the membrane. This application uses flow meter one and flow meter two to monitor the backwashing water flow rate of the ultrafiltration membrane and the normal water production flow rate, respectively. The detection component can detect pressure values at different locations, facilitating timely detection of filter element blockage and reducing maintenance costs and downtime losses due to equipment failure.
