4000L/H Ultrafiltration Water Treatment System PVC / PAN / PVDF Membrane

Ultrafiltration Water Treatment System UF Membrane Treatment Plant 4TPH

Ultrafiltration is one of membrane separation techniques driven by pressure. For the purpose of separating large and small molecules, the pore size of the membrane is between 20-1000A°. Hollow fiber ultrafilter (membrane) has the advantages of high filling density per unit container and small footprint.

Ultrafiltration is a pressurized membrane separation technology, that is, under a certain pressure, the small molecules of solute and solvent through a specific aperture of the membrane, while the large molecules of solute can not penetrate, left on one side of the membrane, so that the macromolecular material has been partially purified. Ultrafiltration is one of membrane separation techniques driven by pressure. For the purpose of separating large and small molecules

In the ultrafiltration process, the influencing factors of ultrafiltration efficiency mainly include the following aspects:
① Operating pressure. In the process of ultrafiltration, a gel layer is formed at the interface of the membrane. When the operating pressure increases to a certain value, the permeable flux will not increase with the increase of the pressure, so the operating pressure should be appropriate. Too high pressure will not only not increase the permeable flux, but also compact or damage the membrane. The actual ultrafiltration operation should be carried out near the critical permeable flux, where the operating pressure is about 0.5 ~ 0.6MPa.
② Feed liquid velocity. Increasing the flow velocity of material and liquid can aggravate the turbulence of liquid flow on the membrane surface, which is conducive to slowing down the concentration polarization and improving the processing capacity of the equipment. However, if the flow velocity of material and liquid is too high, the operating cost of the system will increase with the increase of energy consumption. Therefore, the flow velocity of material and liquid should be controlled within the appropriate range. In general, the flow rate of ultrafiltration liquid is 1 ~ 3m/s.

③ Pretreatment of material liquid. In order to ensure the normal and stable operation of the ultrafiltration system and improve the ultrafiltration efficiency, it is necessary to pretreat the material liquid before ultrafiltration. The main object of material liquid pretreatment is suspended matter and pH value, pretreatment method according to the material liquid properties and needs to be selected, can be used accordingly filtration, chemical coagulation and pH adjustment, disinfection, activated carbon adsorption and other methods.
(4) Operating temperature. The operating temperature of the system mainly affects the viscosity of the operating liquid. Under the condition that the material of the film and the processed liquid allow, increasing the operating temperature is conducive to increasing the mass transfer efficiency and improving the permeable flux.
⑤ membrane cleaning. When the permeable flux of the membrane attenuates to a certain extent, it is necessary to clean. Membrane cleaning methods include hydraulic cleaning, pharmaceutical cleaning and mechanical cleaning, which should be determined according to the properties of membrane and treatment material liquid and the type of membrane components.
