In order to inhibit scaling, the electrode is automatically reversed. When the electrodes are reversed, the polarity of the electrodes is exchanged, and the moving direction of ions among the membrane stacks is changed, so that the concentrated water channel is changed into a fresh water channel, and the fresh water channel is changed into a concentrated water channel. The polarity is determined by the electrode charging at the bottom of the stack.
When the electrodes are reversed, the fresh and concentrate flows are reversed. Thus, water flows through the membrane surface, the concentrated water channel reduces dirt and sewage in a self-cleaning mode, and the recovery rate can be improved. In the pole-reversing process, the automatic operation valve alternately switches the water inlet and the water outlet, so that the inlet water flows into a new fresh water chamber, and the backflow concentrated water flows into a new concentrated water chamber. The factor influencing the pole-reversing process is that the concentrated water is retained in the membrane pile, the salinity of the concentrated water is greatly higher than that of the raw water, and the concentrated water must be desalted. This results in a brief period of time during which the salinity of the fresh water (product water) is above the specified limit. This small portion of water is referred to as reject water. And the unqualified water enters the wastewater through the conductivity control valve until the water quality meets the requirement.
