The ultrafiltration water treatment system is mainly composed of three processes: pretreatment, ultrafiltration mainframe and post-treatment. The core process of the ultrafiltration unit uses ultrafiltration membrane separation technology to remove some harmful impurities in the water larger than the pore size of the membrane by its physical retention method. Under the action of a certain pressure, organic low molecular and inorganic ions in the solution can pass through the membrane to the other side, and impurities such as bacteria, insoluble colloids, particulate matter, and organic macromolecules in the solution cannot be trapped through the membrane element. It achieves the purpose of purifying and separating water quality.

Introduction of various process components of ultrafiltration membrane system

Pretreatment consists of quartz sand, activated carbon, and precision filtration equipment. It mainly removes sediment, rust, colloidal substances, suspended solids, pigments, odors, organic matter, reduced residual ammonia value and pesticide pollution in raw water. the process of. If the content of calcium and magnesium ions in the raw water is high, a soft water device is also needed. The main purpose is to protect the ultrafiltration membrane of the latter stage from the destruction of large particulate matter and meet the requirements of reverse osmosis water in order to prolong the original membrane. Service life.

The ultrafiltration mainframe is mainly composed of a booster pump, a membrane casing, an ultrafiltration membrane module, a control circuit, etc., and is a core part of the entire water treatment system.

The main purpose of the post-treatment part is to further treat the water quality prepared by the ultrafiltration mainframe. The ultrafiltration device must be equipped with post-sterilization equipment, such as ultraviolet germicidal lamp or ozone generator, to prepare the water quality. Drink directly.

Application fields of ultrafiltration membrane technology

1. Pure water, ultrapure water: primary purification of industrial water, reverse osmosis pretreatment, terminal treatment.

2. Fermentation: separation of biochemical fermentation broth, enrichment and refining of enzyme, and clarification filtration of xylitol.

3. Medicine: In the preparation of biomedical chemical, it is necessary to purify and separate the heat sensitive substance.

4. Environmental protection: advanced treatment of industrial wastewater, urban water reuse system, electrophoretic paint and oil recovery.

5. Mineral water: Ultrafiltration technology is applied in the manufacture of mineral water. In the design, according to the analysis report of water quality, the pore size and membrane type of the membrane are selected in a targeted manner.

6, food: dairy products, juice, wine, spices and other food production process using ultrafiltration technology, such as milk or whey protein and low molecular weight lactose and water separation, wine colored protein, polysaccharides and other colloidal impurities The removal, etc., the removal of bacteria in soy sauce, vinegar, the mature ultrafiltration membrane separation technology and unique advantages are widely used.
