Monroe Water Treatment Plant<\/h1>\n\n\n\n

Summary of Operations and Service Work<\/h2>\n\n\n\n

The City of Monroe Water Treatment Plant, located at 915 E. Front Street, Monroe, Michigan, has been providing safe drinking water to the community for over a century. (see link to article)<\/a>. <\/p>\n\n\n\n

The facility draws water from Lake Erie, sharing an intake with the Frenchtown plant. Due to the lake\u2019s shallow depth and seasonal algae blooms, the plant faces ongoing challenges with algae toxins and organic contaminants during the summer months. We were able to help the nearby Frenchtown Water Treatment plant this summer with ozone leak problems. When Monroe learned about us from Frenchtown, they were eager to have us help them as well.<\/p>\n\n\n\n

To ensure reliable disinfection and oxidation, the plant pre-treats all incoming water with ozone year-round\u2014a process they adopted roughly 30 years ago with the installation of a Wedeco GS-200 ozone generator. Monroe has upgraded its ozone capability with a new Ozonia 250 lb\/day ozone generator, which currently serves as the primary system. But, the Ozonia system has proven incompatible with the plant\u2019s backup power generators, which supply power with too much electrical noise. A second 250 lb\/day Ozonia unit is on order for installation in about a year, with hopes that the manufacturer will resolve the power compatibility issues before commissioning. In the meantime, they asked us to help rebuild their old Wedeco GS 200 ozone generator and provide information and training for all their ozone related equipment.<\/p>\n\n\n\n

Oxidation Technologies was on site to inspect, rebuild, and restore the Wedeco GS-200 ozone generator for supplemental use, as well as to evaluate and maintain ozone monitoring and oxygen supply systems throughout the plant.<\/p>\n\n\n\n

After getting the cell rebuilt and turned it back on, a “High Voltage DC Failure” warning came on.  That’s when we learned that this was the error from the start when they first had problems. We still needed to find the heart of the problem.  <\/p>\n\n\n\n

Eventually the heart of the problem was exposed as a failed resistor.  The electrician was able to order a new one and we were able to leave with some confidence that they would be able to get the generator up and running.  <\/p>\n\n\n\n

Customer had taken out all 250+ dielectrics from the cell bundle and had them laid out on a rack they made for these.  They bought 50 new dielectrics from Wedeco, so we first installed 50 new ones, and then the best of the used ones.  <\/figcaption><\/figure>\n<\/div>\n\n\n\n

These are the new dielectrics installed.  You can see that at some point the customer welded some of the tubes closed because they were leaking cooling water.<\/figcaption><\/figure>\n<\/div>\n\n\n\n

Applying high voltage to test the dielectrics.\u00a0 Everything tests out perfectly here.\u00a0 Unfortunately, after putting the cap back on and tipping the cell upright, this cell failed the test and needed to be taken ALL apart again to find the one bad one.\u00a0 Turned out, three were bad.\u00a0\u00a0<\/figcaption><\/figure>\n<\/div>\n<\/div>\n\n\n\n
