Cartridge Filters: Applications, Types, and Benefits
Where, Why, and for What Purpose Are Cartridge Filters Used?
Cartridge filters are effective filtration elements used to remove particles from various liquids. These filters are widely preferred in different industries such as water, paint, solvent, glucose, pharmaceuticals, oil, alcohol, cosmetics, electronic equipment manufacturing, printed circuit boards, wine, and beer filtration. They can be manufactured as depth or surface filters from different materials to separate solid particles, sediments, and even certain chemicals from flowing liquids.
Due to their industrial diversity, cartridge filters can be adapted to almost any sector. They stand out with their ease of use and low maintenance requirements. These filters are used for clarification and classification purposes. With various types available, cartridge filters have a broad filtration rating range from 0.05 microns to 100 microns. They are ideal for industries requiring high hygiene and precision, such as pharmaceuticals, cosmetics, and electronic circuit manufacturing, as they can effectively filter all particles down to 0.05 microns.
In terms of cost, cartridge filters vary significantly. Some models are highly economical, while others, with advanced technology, can be more expensive. However, finding a model that suits the needs of a specific industry or process is always possible.
Types of Cartridge Filters
Cartridge filters are mainly divided into two categories:
-
Depth Filtration
-
Surface Filtration
Depth Filtration
Depth filters operate on the principle of retaining particles within the inner layers of the filtration media. These filters are made from materials such as polypropylene, polyester, acrylic, and cellulose. Spun filters in 40”, 30”, 20”, and 10” sizes also fall under this category.
Depth cartridge filters are commonly used as pre-filters, such as in reverse osmosis membrane protection. They generally have nominal filtration accuracy and are more efficient when the suspended solids in the liquid are large.
Surface Filtration
Surface filtration cartridge filters work by trapping particles on the surface of the filter media. These filters are typically made from polypropylene or glass fiber. Their pleated structure increases the filtration area, making them more efficient.
These filters have special end caps and do not fit standard cartridge filter housings. Surface cartridge filters generally have absolute filtration accuracy and are used in final filtration stages where finer particles need to be captured. Their micron ratings are lower and more precise compared to depth filters, making them ideal for processes requiring fine filtration.
Choosing the Right Cartridge Filter
Cartridge filters are commonly used in industrial and commercial applications to remove solid particles from liquids. However, due to their variety in materials, sizes, and micron ratings, selecting the correct filter requires a thorough understanding of the process's filtration needs.
