Selecting the right filters can minimize process downtime, reduce maintenance and waste disposal costs, limit worker exposure to the fluids, and improve product quality. However, proper filter selection can vary amongs industrial applications, including water filtration, boilers and irrigation. When it comes to liquid processing, consider these two basic filters:
Bag Filters
Liquid bag filters operate by capturing solids inside the filter media “bag”, and tend to be low cost. They generally have lower surface areas than comparable cartridge systems. Due to their wide range of process conditions, they’re a great choice for a variety of applications, including paints, water treatment, food processing, pharmaceutical, and more.
Cartridge Filters
Cartridge filters are used for removing suspended solids for applications with lower flow rates, where exposure to the process liquid is not an issue. They are typically the same initial cost as bag filters, but contain a higher operational cost.
If operator and environmental exposure to the liquid is acceptable, and loss solids must be removed, both bag filters and cartridge filters are recommended. When selecting a filter for liquid processing, it’s important to ultimately consider the cost, flow requirements, and operator exposure risks.
