UF system for drinking water flow chart:
Ultrafiltration membranes are used extensively in water treatment projects. Ultrafiltration technology plays an increasingly important role in the fields of reverse osmosis pretreatment, drinking water treatment, and reuse of water. Ultrafiltration technology plays a key role in the sterilization and turbid removal of alcohol and beverages, the depyrogenation of pharmaceuticals, and the concentration of foods and pharmaceuticals.
The range of ultrafiltration filtration pore size and molecular weight cut-off has been ambiguously defined. It is generally considered that the ultrafiltration membrane has a filtration pore size of 0.001 to 0.1 μm and a molecular weight cut-off (MWCO) of 1,000 to 1,000,000 Dalton. Strictly speaking, the ultrafiltration membrane has a filtration pore size of 0.001 to 0.01 μm and a molecular weight cutoff of 1,000 to 300,000 Dalton. A microporous membrane with a filtration pore size greater than 0.01 μm or a molecular weight cutoff greater than 300,000 Dalton should be defined as a microfiltration membrane or a fine filtration membrane.
Ultrafiltration membranes commonly used for water treatment have a nominal molecular weight cutoff of 30,000-300,000 Dalton, while ultrafiltration membranes with a molecular weight cutoff of 6,000-30,000 Dalton are mostly used in the separation, concentration, sterilization and heat removal of materials.
The form of the ultrafiltration membrane can be divided into two types, a plate type and a tube type. The tubular ultrafiltration membrane is further classified into hollow fiber, capillary tube and tube type according to the diameter of the tube. The ultrafiltration membranes used for water treatment on the market are basically capillary type, and the hollow fiber (inner diameter 0.1-0.5 mm) polyethylene or polypropylene microporous membrane used in individual projects should actually belong to the microfiltration membrane.
The assembly of ultrafiltration membrane filaments into a module that can be coupled to an ultrafiltration system is referred to as an ultrafiltration membrane module. The ultrafiltration membrane modules are classified into three types: internal pressure type, external pressure type and submerged type. The driving force of the immersion ultrafiltration membrane filtration is the pressure difference between the vacuum inside the membrane tube and the atmospheric pressure. For ultrafiltration membranes with high filtration accuracy, this pressure difference is usually not easy to meet the required filtration driving force, so the submerged component form is suitable for ultrafiltration membranes or microfiltration membranes with low filtration precision. When the external pressure type ultrafiltration is used in the forward and reverse strokes, the flow rate of the liquid on the surface of the membrane is extremely uneven, which affects the flushing effect on the surface of the membrane. Therefore, the ultrafiltration membrane commonly used for water treatment or the internal pressure type component structure has advantages.
