Treatment of Aerospace Machining and Inspection Wastewater

"What's the most economical, acceptable, compliance-based solution?"
In our latest podcast episode, we sat down with returning guest Michael J. Soller P.E. CPC, DBIA the Vice President of Business Development at Bowen Engineering Corporation. Michael shares his deep expertise in compliance, problem-solving, and project management in the treatment of industrial wastewater discharge. Drawing from his technical paper titled "Treatment of Aerospace Machining and Inspection Wastewater," published through the International Water Conference (IWC), Michael's insights offer valuable lessons for both seasoned professionals and newcomers to the field.
What was the challenge in treating aerospace machining wastewater? Michael's team was tasked with solving a unique and complex problem: treating wastewater from aerospace machining and inspection processes, which included both oily and chemical-laden water. The challenge? The wastewater had a makeup that was difficult to treat using standard industrial methods due to high variability in water quality, coupled with strict environmental regulations.
Michael explains, "The project demanded an innovative approach to remove oils, emulsifiers, and heavy metals, all while ensuring that we met the discharge standards set forth by regulatory bodies." His team had to develop a custom treatment system that could handle the specific composition of the wastewater and still operate efficiently on a day-to-day basis.
How was the technical problem solved? Michael's approach revolved around advanced treatment technologies. His team implemented a combination of physical separation processes, chemical treatment, and membrane filtration to address the variable wastewater composition. They also designed the system to operate within tight environmental discharge limits.
"We needed a solution that was flexible yet robust enough to consistently meet compliance while accounting for changes in water makeup," he says. His team's strategy of using adaptable treatment methods ensured that the system could be fine-tuned as needed without sacrificing performance or sustainability.
How Can We Ensure Compliance in Wastewater Management? Michael walked us through a crucial aspect of industrial water treatment: staying in compliance with local discharge standards. Daily monitoring, regular equipment maintenance, and thorough record-keeping are essential. As Michael put it, it's a simple equation: "Either they're in compliance or they're not."
One standout example is how his client wisely operated at a 60-70% capacity rather than pushing their system to 100%. This allowed room for planned maintenance and unexpected issues without jeopardizing compliance. Michael highlighted the importance of planning for maintenance, saying, "They know they're going to have variability, so they plan accordingly." This proactive approach minimizes the risk of being caught off guard and incurring fines or downtime.
Managing Projects Without Sacrificing Capacity In industrial projects, there's often a temptation to "value engineer" and eliminate extra capacity to cut costs. Michael shared a compelling example of how a customer made a deliberate choice to avoid this pitfall, ensuring they had the necessary leeway to maintain and repair equipment without maxing out their system's capacity.
For customers who may be hesitant about building in extra capacit
