It’s well known that water filtration is an essential step in industrial processes helping remove impurities and contaminants, and ensuring consistent water quality. It safeguards equipment, enhances product quality, promotes efficient operations, and reduces downtime and maintenance costs.
However, central to the efficacy of water filtration systems are filter housings, which provide structural support and protection to the filtration elements. These housings play a pivotal role in maintaining water quality and optimizing industrial processes.
Several Common Filter Housing Materials
- Stainless Steel
- Carbon Steel
- Fiberglass-reinforced plastic (FRP)
- Polypropylene (PP)
- Polyvinyl Chloride (PVC)
- Polyethylene (PE)
- Cast Iron
- Aluminum
- Exotic Alloys
- Ceramics
In this article, we will explore the exceptional attributes of Fiber-Reinforced Plastic (FRP) filter housing and find out why it is a superior choice for industrial water filtration.
Understanding FRP Material
FRP stands for Fibre-reinforced plastic or fiber-reinforced polymer. It is a composite material made of a polymer matrix reinforced with fibers, typically glass (in fiberglass) or carbon (in carbon-fiber-reinforced polymer).

This combination imparts unique characteristics to FRP, making it an ideal choice for filter housing in industrial water filtration applications.
Key Features of FRP Housing
Corrosion Resistance
Corrosion can wreak havoc on industrial equipment and filtration systems. FRP filter housing’s innate resistance to corrosion ensures that it remains robust and reliable, even when exposed to corrosive substances or harsh environmental conditions. This resistance safeguards water quality and extends the housing’s longevity.
Exceptional Durability
FRP filter housings are renowned for their exceptional durability. They exhibit high strength-to-weight ratios, allowing them to withstand extreme conditions without succumbing to wear and tear. This durability translates into a longer lifespan, reducing the need for frequent replacements and associated costs.
Lightweight Design
One of the standout features of FRP filter housing is its lightweight design. This attribute simplifies the installation process, reducing the need for heavy machinery and labor-intensive efforts. It not only saves time but also lowers installation costs.
Versatility in Customization
The versatility of FRP as a material allows for intricate design customization. FRP filter housings can be tailored to meet the specific requirements of diverse industrial applications. Whether it’s adjusting dimensions, inlet/outlet configurations, or other design aspects, FRP offers flexibility that caters to unique filtration needs.
Due to the above important characteristics, FRP housing has the following advantages compared with other materials of filter housings.

Advantages of FRP Filter Housings
Longevity and Durability
FRP filter housings are engineered to withstand the test of time. Their resistance to corrosion and chemicals ensures a longer lifespan, reducing the frequency of replacements. This longevity translates into cost savings and uninterrupted industrial processes.
Lightweight Installation
The lightweight nature of FRP filter housings simplifies the installation process significantly. Unlike heavier alternatives, which may require heavy lifting equipment and additional labor, FRP housings can be installed more efficiently and cost-effectively.
Low Maintenance
FRP filter housings are low-maintenance, requiring minimal attention to remain in optimal condition. Their resistance to corrosion and easy-to-clean surfaces contribute to a hassle-free maintenance experience. Reduced downtime and maintenance costs are valuable benefits for industrial operations.
Commonly Used Types of FRP Filter Housing
FRP Bag Filter Housing

FRP bag filter housings are designed to hold filter bags, making them suitable for applications where larger particles need to be removed from the water. They are commonly used in industrial processes to safeguard equipment and maintain water quality.
FRP Cartridge Filter Housing

FRP cartridge filter housings accommodate cartridge filters, which come in various materials and micron ratings. They are versatile and effective in removing sediment, particulate matter, and contaminants from industrial process water.
FRP High-Flow Filter Cartridge

FRP high-flow filter cartridge housings are employed for applications with high flow rates and larger filtration capacities. These housings can handle significant water volumes while ensuring efficient filtration.
Likefilter not only provides a single piece of FRP filter housing but also has the FRP filter skid or set (combine a few single housings, such as below picture), it depends on the project flow rate.

Applications of FRP Filter Housings
FRP filter housings find application across diverse industrial sectors, contributing to the efficiency and reliability of water filtration processes.
- Industrial Water Treatment
- Chemical Processing
- Food and Beverage Production
- Pharmaceuticals
- Seawater Desalination
- Condensate Water Filtration
- RO Pre-filtration

Maintenance and Troubleshooting of FRP Filter Housings
Proper maintenance is key to maximizing the benefits of FRP filter housings and avoiding potential issues. Here are some general maintenance guidelines and troubleshooting tips:
Leaks or Pressure Drop
Inspect the housing seals and gaskets if you encounter leaks or a significant pressure drop. Ensure they are properly seated and not damaged.
Cleaning and Filter Cartridge Replacement
Regularly clean the housing’s interior and replace filter cartridges as recommended by the manufacturer to maintain filtration efficiency.
Preventing Corrosion
Regular inspections help identify signs of corrosion. If corrosion is detected, address it promptly to prevent further damage to the housing.
When to Replace
Replace your filter housing if it shows signs of extensive wear or damage, or if it no longer meets your filtration requirements.

Conclusion
In conclusion, the excellence of FRP filter housing in industrial water filtration benefits from its lightweight design, exceptional durability, corrosion resistance, and versatility in customization.
These qualities make FRP filter housing an ideal choice for a wide range of industrial applications, from water treatment to chemical processing, food and beverage production, and pharmaceuticals.
As industries increasingly recognize the importance of water quality in their processes, embracing FRP filter housing excellence becomes paramount.
Its pivotal role in maintaining water quality, safeguarding equipment, and optimizing industrial operations positions it as a cornerstone of industrial water filtration.
By choosing FRP filter housing, industries can look forward to improved efficiency, cost-effectiveness, and a brighter, more sustainable future for their water treatment endeavors.
