In filtration, there is a precision filter, which is also called a security filter. It is widely used in prefiltration and filtration, which can effectively remove contaminants from water. This blog aims to introduce this precision filter to you, and help you know more about water treatment
Due to its characteristics of large filtering surface, fast speed, non-clogging, and ease to use, therefore, widely used in pretreatment and final filtration of various industries. Precision filters are available in quick-open type, flange type, and clamping type.
Characteristics of precision filter
The precision filter has a perfect appearance, simple and reasonable structure, polished inside and outside.
Not only good at appearance but also good at filtration, it has a large filtering area, fast filtration speed, low clogging rate, acid, and alkali corrosion resistance, and long service life. At the same time, the precision filter has a lower cost, a small footprint, and a large filtration surface.
With different types and micron ratings inside filter cartridges, the precision filters can remove all kinds of tiny particles, colloids, metals, bacteria, residual chlorine, and other impurities from the liquids.
- Able to withstand high filtration pressure can effectively remove suspended matter, rust, etc. in the liquid
- Cartridges can be made from a variety of materials to suit a variety of fluid filtration needs
- Small footprint, large filtration area, low resistance, and long service life
- Resistant to acids, alkalis, and other chemical solvents
- With high filtration precision, the uniform pore size of the cartridge, high strength, and high-temperature resistance, the cartridge is not easy to deformation
Working principle of precision filter
The precision filter is made of formed filter material. Under the effect of pressure, the original liquid passes through the filter material, the filter residue remains on the wall of the filter material, and the filtrate flows out through the filter material, which can effectively remove impurities, sediment, suspended matter, and bacteria from the water.
It can effectively remove impurities, sediment, suspended matter, and bacteria from the water, thus achieving the purpose of filtration.
Formed filter materials include filter cloth, filter mesh, filter sheet, sintered filter tube, string wound filter cartridge, melt blown filter cartridge, microporous filter cartridge and multifunctional filter cartridge.
Due to the different materials, the filtration pore size is also different. Precision filtration is a kind of filtration between sand filtration (coarse filtration) and ultrafiltration, and the filtration pore size is generally in the range of 0.1-120μm.
The Classification of precision filters for water treatment
The precision filter is mainly divided into B, C, and D grade precision filters, according to the different types and grades, its main applications are not the same.
Class B, and C precision filter is mainly used in environmentally-friendly fiber and non-woven fabric materials; Class D filter is similar to activated carbon filter, mainly used in pharmaceutical, food, water treatment, petroleum, printing, and other industries. Of course, it is also the ideal equipment for all kinds of liquid filtration.
The performance of the precision filter
- The oil& gas in compressed air can be filtered to 0.5ppm. At the same time, impurities are filtered to 5 Micron
- Oil and gas can be removed to 0.01ppm; And the impurities in the air can reach 0.01Micron
- Able to remove the ozone in the compressed air, ultra-fine particles, and even imperceptible particles in oil & gas
The application of precision filter
According to the characteristics mentioned above, the precision filter is suitable for pharmaceutical, chemical, food, beverage, water treatment, brewing, petroleum, printing and dyeing, environmental protection, and other industries. It is the ideal equipment for all kinds of liquid filtration, clarification, and purification treatment.
How to choose a precision filter for water treatment
Based on the requirement of sustainability, water issues have repeatedly become the focus of attention. More and more governments and enterprises pay attention to water treatment, and a precision filter is undoubtedly a perfect assistant.
