How to choose a folded filter element-Dongguan Susenyuan folded filter element recommendation

Susenyuan company specializes in the production of folded filter elements, meltblown filter elements, wire wound filter elements and other filter elements. The factory is located in Suzhou, and the Dongguan company is located in Liaobu Town. The filter material has been produced for more than 20 years and is widely used in the semiconductor industry, pharmaceutical industry, food and beverage industry, electronic Industry, LCD flat filter pleated filter element, pleated filter element for semiconductor chip production, photoresist filter pleated filter element, etc., welcome to consult. 1. First figure out whether to filter liquid or gas. The filter membrane material or sealing material should be selected according to the characteristics of the liquid or gas (refer to the chemical compatibility table). Hydrophilic membranes are generally used to filter aqueous solutions, hydrophobic membranes can be used to filter organic solvents, and hydrophobic membranes can be used to filter air. 2. The flow rate of filtration is based on the flux provided by the production process to consider the size of the filter and the number of filter elements. Generally speaking, the flow rate of the filter element (10 inches) is 0.5 tons/hour (the flux of filtered water). For example, to achieve the flux of 1.0T, you can choose a 30-inch filter core, and leave some room for it, because with As the filtration proceeds, impurities accumulate on the surface of the filter membrane, which will lead to a decrease in flux. If a filter with a core of 20 inches is used, it may not meet the requirements. 3. Pressure and temperature The appropriate filter element is determined according to the filtration temperature, pressure and disinfection conditions during filtration. The maximum working temperature of the general filter element is 80~90℃. Activated carbon fiber is 65℃, stainless steel folded is 200℃, titanium sintered filter element can reach 280℃, the maximum pressure is 0.42Mpa/forward, titanium sintered 0.5Mpa, stainless steel folded filter element is 0.6Mpa. 4. Filtration requirements The degree or precision that filtration needs to achieve (requirements for sterilization and particle removal). The filtration efficiency of deep membrane filtration and absolute membrane filtration is different. For example, the absolute accuracy of 0.2um is basically used for sterilization; the relative accuracy of 10-20um can be selected for the removal of visible particles. 5. Several stages of filtration According to the pollution degree of the filtrate and the impurity content, the pre-filter is selected and the number of stages of filtration is confirmed. The purpose of pre-filtration is to prolong the life of the terminal filter and reduce the cost. The design of the pre-filter affects the effect and life of the final filter. PTFE membrane technology plays an indispensable role in cutting-edge fields such as biopharmaceuticals, medical devices, food and beverages, semiconductor processes, and communications. The pore-forming capacity ranges from 0.1m to 1m, providing fine filtration, removal of bacteria and viruses, waterproof, breathable, and sound transmission. PH value for other functional solutions: 1-13. Maximum differential pressure: 25°C, forward 0.4Mpa, reverse 0.2Mpa. Working temperature: under 0.25Mpa, a, general type <70°Cb, high temperature type <90°C. Sterilization: Resistant to 126°C, in-line steam sterilization for 30 minutes. Endotoxin: The water extract of the filter column is tested by lAL, and the endotoxin content is less than 0.5EU/ml. Product Specifications: Customized according to samples. Application fields: Pharmaceutical industry: Pre-filtration of various injections, liquid medicines and injection bottle washing water, pre-filtration of large infusions and various antibiotics and traditional Chinese medicine injections. Food industry: Filtration of alcohol, food and beverages, and drinking water. Electronics industry: pure water, ultra-pure water preparation, liquid crystal panel, circuit board, hard disk, CMP process of wafer production process, lithography process, filtration requirements of cleaning process, terminal filtration of semiconductor wet equipment, terminal filtration of electronic reagents. Petroleum and chemical industry: filtration of various organic solvents, acids and lye, oil field water injection filtration 30 inches, 40 inches and other lengths. For customers with special needs, samples are customized, customized on demand, and free sample trials are provided to ensure product quality and meet customer requirements.
