Detecting industrial discharge events - Case Study
Periodic foaming in an aerated digester and a drop in dissolved oxygen were affecting the performance of the Montague Wastewater Treatment Facility in Three Rivers, Prince Edward Island. "We knew something was upsetting the biology, hut not what it was because the digester returned to normal in a day or two," says Tommy MacLeod, operator. "The situation was exacerbated by our dewatering problems. We occasionally lacked the storage capacity to waste."
The Moniaguc Sewage and Waicr Collection and Treatment Corp. authorized the installation of variable-speed drives on the digester blowers to handle fluctuations in dissolved oxygen. That helped but didn`t address the root of the problem, which turned out to be the addition of two microbreweries to the collections system.
Proving they were responsible required evidence. "We needed scientific data to persuade the owners to work with us toward an amicable solution," MacLeod says.
Fortunately, the town had been in partnership with Island Water Technologies since 2014. The agreement enabled Island Water Technologies to use the Montague planl as a working laboratory. In May 2018, the company began a 12-month pilot of its Sentry technology. Its bioelectrode sensors gave MacLeod real-time insights to variable biological conditions, the necessary irrefutable data and some surprises.
