Filter Leak Monitoring

Filter Leak Detection: What Is It and Why Is It Important?

In industrial processes such as cement manufacturing, chemical production, energy-from-waste and steelmaking, bag filters (housed inside baghouses) are essential for removing solid particulate matter from gas streams. These filtration systems play a vital role in protecting the environment, maintaining safe working conditions and improving process efficiency.

 

However, simply installing bag filters is not enough. Monitoring for filter leak detection in these systems is just as critical, and here is why.

Regulatory Compliance and Worker Safety

Filter leak detection helps facilities comply with local, national and international emissions regulations, including:

  • Control of Substances Hazardous to Health (COSHH)
  • The Health and Safety at Work Act
  • The Industrial Emissions Directive (IED)
  • EN 15859 (what is EN15859)

As regulations continue to tighten globally, operators are under growing pressure to maintain control of particulate emissions. Beyond safeguarding workers and surrounding communities, non-compliance can lead to significant financial penalties. Regulatory bodies regularly issue fines to companies that fail to meet emissions limits, which can have a serious impact on operations and reputation.

Preventing Loss of Valuable Product

In many sectors, the particles collected by bag filters are not waste but high-value materials. This includes:

 

  • Precious metals in mining and refining
  • Active chemical ingredients in pharmaceutical or chemical production
  • Fine powders used in food and electronics manufacturing

If a filter bag develops a leak or ruptures completely, these materials can escape into the atmosphere, leading to measurable product losses. In high-value processes, even a small leak can result in thousands of pounds in lost revenue. Early leak detection allows operators to identify and fix problems quickly, helping preserve valuable product and prevent unnecessary waste.

Reducing Maintenance Costs and Downtime

Bag filters are costly to replace, and the labour required for full filter changeouts can be extensive. In plants where leaks are detected but not located precisely, maintenance teams often resort to replacing every filter in the system to guarantee the issue is resolved.

 

Installing a filter leak detection system helps avoid this. CODEL’s tribo-electric Filter Leak Detectors provide clear, real-time information that highlights which compartments or rows are affected. By monitoring trends during bag cleaning cycles and tracking rising dust levels, the system helps pinpoint problem areas quickly. This approach means:

 

  • Only the damaged filter needs to be replaced
  • Maintenance teams spend less time inside the baghouse
  • Labour and replacement costs are significantly reduced

Anyone who has spent time working inside a baghouse will understand the value of reducing maintenance time wherever possible!

Supporting Smarter Maintenance Decisions

Filter Leak Detectors provide more than just basic alerts. They deliver continuous performance data that supports proactive maintenance strategies. With this information, operators can:

 

  • Monitor filter condition over time
  • Detect early signs of failure before major issues arise
  • Plan maintenance based on actual filter performance
  • Maintain consistent emissions control without relying on guesswork

This kind of insight allows plants to move away from reactive maintenance routines and adopt a more efficient, data-driven approach.

Conclusion

Filter leak detection is essential for any industrial site that relies on bag filters to control emissions. Whether the goal is compliance, cost reduction, product recovery or improved efficiency, the advantages of monitoring are clear.

 

CODEL’s Filter Leak Detectors are trusted by a wide range of industries and are designed to operate reliably in tough, dust-heavy environments.
