Odor control systems are essential for industries and municipalities dealing with wastewater, biosolids, or industrial processes. However, even the best-intentioned projects can fall short if common design mistakes are not addressed. At Webster Environmental Associates (WEA), we have seen it all. From undersized equipment to poor maintenance planning, we are here to help you avoid these pitfalls.
With over 750 successful odor control projects under our belt, we know what works and what does not work. Let’s dive into the five most common mistakes in odor control system design and how to steer clear of them.
Mistake 1: Underestimating Odor Load
What Happens?
Many facilities design their odor control systems based on average odor loads, only to find the system overwhelmed during peak conditions. This leads to breakthrough odors, complaints, and potential regulatory issues.
Why It Happens:
- Odor loads can varysignificantly due to seasonal changes, process upsets, or operational fluctuations.
- Facilities may not account for future growth or changes in waste streams.
How to Avoid it:
- Conduct a comprehensive odor study to measure peak loads, not just averages.
- Work with an experienced engineer to size equipment for worst-case scenarios.
- Plan for scalability. Design systems that can expand as your facility grows.
Mistake 2: Choosing the Wrong Technology
What Happens?
Not all odor control technologies are created equally. A biofilter might work wonders for organic odors but fail miserably for chemical odors. Similarly, a chemical scrubber could be overkill for a facility with odor concentrations.
Why It Happens:
- Facilities may select technology based on cost or familiarity rather than suitability.
- Lack of expertise in matching odor types or the right treatment method
How to Avoid It:
- Consult with an odor control specialist to identify the best technology for your specific odor profile.
- Consider pilot testing different systems before committing to a full-scale installation.
- Evaluate operational costs, not just from expenses.
Mistake 3: Ignoring Maintenance Requirements
What Happens?
Odor control systems are often installed with little regard for ongoing maintenance. This leads to clogged filters, fouled media, and system failures. All of which can result in odor breakthroughs and costly repairs.
Why It Happens:
- Facilities may not budget for regular maintenance or staff training.
- Maintenance schedules are based on optimistic assumptions rather than real-world conditions.
How to Avoid It:
- Develop a detailed maintenance plan before installation, including filter replacements, media changes, and system inspections.
- Train staff on basic troubleshooting and routine upkeep.
- Partner with a vendor that offers ongoing support and service contracts.
Mistake 4: Poor System Integration
What Happens?
Odor control systems do not operate in a vacuum. They need to integrate seamlessly with your existing processes and infrastructure. Poor integration can lead to inefficient operation, increased energy use, or even system failure.
Why It Happens:
- Systems are designed in isolation, without considering how they will fit into the broader facility.
- Lack of coordination between engineers, operators, and vendors during the design phase.
How to Avoid It:
- Involve all stakeholders (engineers, operators, maintenance teams) in the design process.
- Ensure the system is compatible with existing equipment and control systems.
- Plan for easy access to system components for maintenance and repairs.
Mistake 5: Overlooking Community and Regulatory Needs
What Happens?
Even the most technically sound odor control system can fail if it does not address community concerns or meet regulatory requirements. This can lead to public backlash, fines, or even shutdowns.
Why It Happens:
- Facilities focus on technical performance without considering the human impact of odors.
- Regulatory requirements are overlooked or misunderstood during the design phase.
How to Avoid It:
- Engage with the community early to understand their concerns and expectations.
- Work with an odor control expert who understands local, state, and federal regulations.
- Design systems that not only meet compliance standards but also exceed community expectations.
Case Study: Avoiding Mistakes in Action
In a recent project, WEA worked with a municipal wastewater treatment plant struggling with persistent odor complaints. The facility had installed a biofilter years earlier, but it was undersized and poorly maintained. Odors were breaking through, and the community was frustrated.
Our team conducted a detailed odor study and found that the system was underestimating peak odor loads and using the wrong media for the odor profile. We recommended upgrading to a bio trickling scrubber and implementing a rigorous maintenance plan. The result? A 90% reduction in odor complaints and a system that is built to last.
