How do you choose the right filter housing for your application?

Choosing the right filter housing for a specific application can be overwhelming. In this article, we discuss the main types of filter housings and their unique advantages and disadvantages. This will give you a good idea of the filter housing that best suits your specific needs.

What is a Filter Housing?

A filter housing is the shell structure that contains a specific filter. This filter housing ensures that unwanted particles are removed from a fluid. They are essential in a variety of industrial and commercial applications, where reliability and accuracy are crucial for optimal performance. Filter housings are available in various materials, such as stainless steel (SS 304, 316, and 316L), polyurethane, and duplex 2205, depending on the application and required chemical resistance.

Advantages and disadvantages of filter housings

Advantages:

1. Durable and resistant to high pressure: many filter housings, especially those made of stainless steel, can withstand extreme pressures and temperatures. They are often designed to withstand even the harshest industrial environments.
2. Easy maintenance: many filter housings, such as basket strainers, have a flip-up lid, which makes maintenance and replacement of the filter element easy without long downtimes.
3. Flexible applications: from wastewater treatment to the food industry, filter housings are versatile and can be adapted to specific needs.

Disadvantages:

• Cost of custom housings: custom filter housings can be more expensive, especially when using specialty materials or complex configurations.
• Periodic maintenance required: for long-term efficiency, a filter housing must be checked and cleaned regularly, which can incur additional costs and downtime.

Technologies within filter housings

Filter housings are distinguished not only by their materials, but also by the technologies they support, depending on specific industry needs.

1. Single- and Multi-Cartridge Filters: these filter housings contain one or more filter candles and are ideal for applications where a higher degree of fineness is required, such as in the pharmaceutical and food industries. Multi-cartridge systems can be equipped with more than 100 filter candles, providing high flow rates and precise filtration.
2. Multi Bag Filters: for high flow applications, such as cooling water or wastewater, multi-bag filter housings are suitable. These can hold up to 14 filter bags, so they can handle high volume and work well for coarse filtration.
3. Cyclone and Hydrocyclone Filters: cyclone filters, including sand separators and hydrocyclones, are designed to separate heavy solids from liquid streams by centrifugal force. They are commonly used in the chemical industry and wastewater treatment.
4. Basket Strainers and Simplex Filters: basket strainers, often used to protect pumps, capture larger particles and are suitable for water with sediment. Simplex strainers are simpler and are used in processes with limited space and less demanding filtration requirements.

Applications of Filter Housings

Filter housings find their way into a wide range of industries because of their versatility and adaptability:

• Petrochemical and Offshore Industry: filter housings such as multi-cartridge and cyclone filters are used in these industries to keep oil and other liquids free of solid contaminants.
• Food industry: strict hygiene and safety standards apply here. Multi-bag and cartridge filter housings are used to ensure high filtration precision.
• Water Treatment and Waste Management: in water treatment plants, various filter housings, such as sand separators and basket strainers, are effective in removing large amounts of solids from wastewater.

Conclusion

Choosing the right filter housing depends on the specific needs of the application and the nature of the fluid being filtered.
