Filtering Out Confusion—Select the right liquid filter media for the right process

摘要

Filtration is a basic concept that's integral to aseptic processing. Whether you're talking about ultrapure water, high-purity products or process chemicals, the basic idea is to remove contaminants from the fluid stream. Depending on the application,the product itself may be filtered, as is the case with milk processing and paint/ink manufacturing, or contaminants during the manufacturing process may be filtered out, as is the case with the manufacture of dielectric insulations, fuel additive processing and metalworking applications. While the concept may be simple, the process of liquid filtration can be complicated, That's because in liquid filtration, one encounters a wide variety of fluid chemistries, High fluid temperatures are common, as arehigh viscosity and flow rates. There is also a wide range of particle sizes. In addition, the filtration process may require separation of particles, gels and solutions, Finally, high-cost processes depend on filtration, adding a significant financial incentive to installing the right filtration system.
