Description: W14-Proceedings
In Situ Mixed Liquor Sampling and Testing Device Provides Real Time Biota Health Monitoring
Abstract
A newly invented instrument residing in an activated sludge aeration basin, combines continuous measurements and batch-samples mixed liquor to run a battery of tests every twenty minutes. The device provides oxygen uptake rate measurements on active mixed liquor, while also measuring dissolved oxygen, ammonia nitrogen, pH, temperature, mixed liquor suspended solids and settling rates. Integrated self-cleaning steps keep probes clean. In its first installation in North America, at the Town of Milford, New Hampshire Wastewater Treatment Facility (WWTF), four week’s worth of online data has been collected and is analyzed herein.
