Filtration principle
The filtration principle of Capsule Filters is based on physical barrier filtration, which captures and removes tiny particles and bacteria in the liquid through internal high-precision membrane materials. Its 0.2 micron pore size ensures that only particles smaller than the pore size are allowed to pass through, while larger particles are trapped on the surface of the filter membrane. The fine and uniform microporous structure of the membrane can achieve efficient particle filtration while maintaining a high flow rate and low pressure drop, ensuring the stability and efficiency of the filtration process.
Main Application Areas
They are widely used in the biopharmaceutical industry for the clarification and sterile filtration of drug solutions to ensure the safety and purity of drugs. In the food and beverage industry, it is used for microbial filtration of products such as beverages, beer, and mineral water to ensure the hygiene standards of the products. In the chemical industry, capsule filters are used to filter fine chemicals, remove impurities, and improve product quality. In addition, in laboratories and R&D environments, it is used for sample preparation and pre-analysis filtration to ensure the accuracy of experimental results.
Technical Advantages
This filter element uses advanced membrane technology to provide excellent chemical compatibility and high temperature resistance. Its membrane materials include polyethersulfone (PES), polypropylene (PP), nylon (NYLON), etc., and the appropriate material can be selected according to different filtration needs. Its structural design is optimized to maintain a stable filtering effect at high flow rates and reduce operating time. The filter housing is usually made of corrosion-resistant plastic or stainless steel to ensure long-term use in harsh environments.
Economic Benefits
