Tampa Plant Reduces Operating Costs with Online Process Analyzers
Tampa AWTP improves its efficiency by installing online process analyzers to monitor and control nitrification and denitrification processes.
The Howard F. Curren Advanced Wastewater Treatment Plant is Tampa's only wastewater treatment plant, so the volume and characteristics of the influent flowing into the plant vary constantly. This makes access to reliable real‐time information critical for optimal process control.
Years ago, plant managers recognized that attempting to operate the plant without data on real-time conditions was like trying to hit a target while blindfolded. Lack of timely information about nitrification and denitrification processes meant operators often had to make educated guesses about what adjustments were needed. They also needed to spend hours on testing, often one step behind any issues that arose.
To keep operators informed about nitrification and denitrification processes, plant management invested in three ChemScan Online Analyzers.
The analyzers provide operators with automated sampling and online, real‐time results. At two points on the six stages in the plant's nitrification reactors, the analyzers automatically draw samples and then analyze them for nitrate and ammonia.
The ChemScan Online Analyzers use fully automated ultraviolet‐visible spectrometry to measure absorbance levels across 256 wavelengths of light. A single process analyzer can monitor up to eight sample points, separately detecting ammonia, nitrite and nitrate from multiple process sample points or basins.
“Online monitoring has removed the guesswork from optimizing our nitrification and denitrification processes,' says operations specialist Robert Decker.
