Description

Technical Field

[0001] The utility model relates to the field of microfiltration systems, in particular to a pressure tank type microfiltration system. Background Art

[0002] The pressure tank microfiltration system is used to filter and treat sewage through the diversion method of the pressure tank. Microfiltration is widely used in the terminal filtration of ultrapure water in the microelectronics industry, pretreatment of various industrial water supplies and treatment of drinking water. It is also an important tool for detecting fine impurities and conducting scientific experiments in biomedicine and cutting-edge technology. The pressure tank is used in a closed water circulation system to balance the water volume and pressure, avoiding frequent opening of the safety valve and frequent water replenishment of the automatic water replenishment valve. In addition to accommodating the expansion water, the expansion tank can also serve as a water replenishment tank. When the expansion tank is filled with air, a larger volume can be obtained to accommodate the expansion water. The high and low pressure expansion tanks can use their own pressure to replenish water to the pressure stabilization system in parallel;
