Ultrafiltration water treatment equipment

1、 Introduction to ultrafiltration water treatment equipment

Ultrafiltration water treatment equipment is driven by pressuremembrane separationThrough the process of microporous screening on the membrane surface, particles and impurities with diameters between 0.002-0.1 μ m can be intercepted, effectively removing colloids, silicon, proteins, microorganisms, and other impurities from watermacromoleculeorganic compound. When a liquid mixture is pushed through the surface of a membrane under a certain pressure, solvents and small molecules pass through the membranemacromolecular substancesIt is intercepted to achieve the separation and purification of size and molecules. It can be widely applied to the separation, concentration, and purification of substances.ultrafiltrationThe process has no phase transformation, does not require heating, operates at room temperature, saves energy, and is particularly suitable for the separation of thermosensitive substances. The ultrafiltration process is simple, with few supporting devices, easy operation, and low maintenance costs.ultrafiltration membraneResistant to chemical erosion, with a wide range of pH adaptability,ultrafiltration deviceThe membrane area per unit volume is the largest, the investment cost is the lowest, and cleaning is simple.

2、 Principle of ultrafiltration water treatment equipment

Ultrafiltration is a membrane separation process that uses sieving as the separation principle and pressure as the driving force. The filtration accuracy is in the range of 0.005-0.01 μ m, which can effectively remove impurities from waterparticle、colloid、bacteria、heat sourceAnd high molecular weight organic substances. The ultrafiltration process has no phase transformation and operates at room temperature, making it particularly suitable for the separation of thermosensitive substances. It has good temperature resistance, acid and alkali resistance, and oxidation resistance, and can be used continuously for a long time below 60 ℃ and pH 2-11.

The form of ultrafiltration membrane can be divided into two types: plate type and tube type. Tubular ultrafiltration membranes are divided into hollow fiber, capillary, and tubular types according to their different diameters. The ultrafiltration membranes used for water treatment in the market are mainly capillary type, and the hollow fiber (inner diameter 0.1-0.5mm) polyethylene or polypropylene microporous membranes used in some projects should actually belong to microfiltration membranes.

The assembly of ultrafiltration membrane fibers into components that can be connected to ultrafiltration systems is called ultrafiltration membrane components. Ultrafiltration membrane components are divided into three types: internal pressure, external pressure, and immersion. The driving force for submerged ultrafiltration membrane filtration is the pressure difference between the vacuum inside the membrane tube and atmospheric pressure. For ultrafiltration membranes with high filtration accuracy requirements, this pressure difference is usually not easy to meet the required filtration driving force. Therefore, the submerged component form is more suitable for ultrafiltration membranes or microfiltration membranes with lower filtration accuracy. External pressure ultrafiltration has extremely uneven flow velocity of liquid on the membrane surface during forward and reverse flushing, which affects the flushing effect of the membrane surface. Therefore, the ultrafiltration membrane commonly used in water treatment still has the advantage of internal pressure component structure.
