Introduction to ultrafiltration technology:
Ultrafiltration is one of the most widely used membrane technologies, and it is also the membrane with the highest pretreatment filtration precision. Its filtration precision is very high, and the filtration pore size is 0.01-0.2μm. The ultrafiltration membrane is processed on a polymer material. The means is to make micropores with a small aperture. Because the filter pore size is very precise, the ultrafiltration device can not only effectively remove microorganisms, colloids, suspended particles, but also effectively remove bacteria, viruses and heat sources. At present, ultrafiltration is mostly used for surface water, groundwater purification, industrial wastewater reuse, as a pretreatment device for RO systems. At the same time, ultrafiltration is also used in some places where organic matter, colloids and heat sources are removed. However, before the ultrafiltration, a 50 μm microporous filter must be used as a pretreatment device to prevent mechanical particulate fouling of the ultrafiltration device.
The composition of the ultrafiltration system:
Ultrafiltration systems typically consist of a water supply system, a pretreatment system (disc filter and security filter), a backwash system, a dosing system, a membrane cleaning system, and a control system.
Advantages of the ultrafiltration process:
The filtration precision is high, the effluent water quality is good and stable, and it is not affected by the fluctuation of the influent water quality of the system, and the effluent suspended matter and turbidity are close to zero.
High modularity and low footprint.
Low pressure operation, high filtration efficiency and recovery rate, low energy consumption.
The system adopts PLC control, which can realize full automation control.
