Laboratory Study to Determine the Fate of Pyrethroid through Wastewater Treatment Processes
With a sound treatability test under your belt, you can stay focused on the work at hand.
So when our client wanted to show proof positive that pyrethroids found in their wastewater streams were being treated properly, they came to us to conduct a bench-scale investigation in our laboratory.
Together, we decided to test four different conventional wastewater treatment processes. To ensure accuracy, we monitored pyrethroid concentrations at the beginning and end of each treatment process. Primary sedimentation, anaerobic biological treatment and ultrafiltration were performed on a batch basis, and simulated aerobic biological treatment was conducted through a 30-day continuous flow system.
When the results were in, treatability testing proved the client's method of removing pyrethroids through conventional wastewater treatment processes was effective, and established lab-based biodegradation rates for pyrethroids.
