If the cells break open, they release toxin. Dissolved toxin is more challenging for water treatment plants to remove because it can pass through filters and must be removed by chemical means before water leaves the plant for our faucets.<\/p>\n<p>Since July, UToledo scientists have checked on the device&#8217;s wires and tubing to make sure it&#8217;s operating properly. They&#8217;re also doing laboratory experiments at the UToledo Lake Erie Center that are showing the technology is working the way it&#8217;s expected.<\/p>\n<p>&#8220;Our work this summer with the PhycoSens device is the first test of this online algae monitoring system at a drinking water plant in the U.S.,&#8221; said Dr. Thomas Bridgeman, professor of ecology and director of the UToledo Lake Erie Center. &#8220;If we show success at the Toledo Water Treatment Plant and throughout the region to im<a href=\"https:\/\/buradabiliyorum.com\/en\/category\/social-mediaa\/\" data-internallinksmanager029f6b8e52c=\"1\" title=\"Social Media\" target=\"_blank\" rel=\"noopener\">media<\/a>tely detect and notify of toxin release, then it can be scaled up nationwide. So far it&#8217;s showing great promise.&#8221;<\/p>\n<p>The test deployment of the advanced monitoring sensor system is part of a $1.4 million UToledo project funded by the U.S. Army Corps of Engineers that began more than a year ago and focuses on early detection and management of harmful algal blooms.<\/p>\n<p>Since the 2014 Toledo water crisis left half a million residents without safe tap water for three days, researchers have greater clarity that it&#8217;s not just the size and <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/download-scripts-themes-apps\/\" data-internallinksmanager029f6b8e52c=\"9\" title=\"Download Scripts &amp; Themes &amp; Apps\" target=\"_blank\" rel=\"noopener\">app<\/a>earance of the algal bloom that matters, but what is happening in the cells.<br \/>\n                                            <!-- Google middle Adsense block --><\/p>\n<p>Bridgeman&#8217;s devices made by the German company bbe Moldaenke use optical sensors to measure in real time how much and what kind of algae are coming into the water treatment plant, including cyanobacteria. More importantly, the sensors can provide a warning of the cyanobacteria cells breaking open and leaking their contents, including any toxins that they may contain, into the water.<\/p>\n<p>&#8220;A large release of toxin can happen in a matter of hours, and it is critical for water plant operators to have this information so they can adjust their treatment levels quickly, before dissolved toxin can get through the plant,&#8221; Bridgeman said. &#8220;The data are produced every few minutes, which makes it a useful early warning tool for a potentially rapidly changing algal situation.&#8221;<\/p>\n<p>Notable for researchers is data collected in late July showing the peak of the bloom and its decline.<\/p>\n<p>&#8220;So far we have not detected any of that cell breakage at the water treatment plant or near the water intake out in the lake using the automated sensor, which is good <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/news\/\" data-internallinksmanager029f6b8e52c=\"2\" title=\"News\" target=\"_blank\" rel=\"noopener\">news<\/a>,&#8221; Bridgeman said. &#8220;However, UToledo crews on our research vessel taking water samples out in the lake throughout Lake Erie&#8217;s western basin\u2014not near the water intake\u2014have detected cell breakage using the manual version of the same device this season.&#8221;<\/p>\n<p>Bridgeman said that cell breakage events leading to large releases of dissolved toxin don&#8217;t happen every year in Lake Erie.<\/p>\n<div class=\"article-gallery lightGallery\">\n<div data-thumb=\"https:\/\/scx1.b-cdn.net\/csz\/news\/tmb\/2022\/utoledo-first-in-us-to-1.jpg\" data-src=\"https:\/\/scx2.b-cdn.net\/gfx\/news\/hires\/2022\/utoledo-first-in-us-to-1.jpg\" data-sub-html=\"Dr. Kuo-Pei Tsai, a post-doctoral research associate at the UToledo Lake Erie Center, works at the city's raw water pump station with the plastic storage tub containing a game-changing technology in the fight against toxic algae.

His laboratory is one of the key locations for tracking and providing early warning of harmful algal blooms in the western basin of Lake Erie.<\/p>\n<p>He said while the new instruments can detect the health, or physiological condition, of the cyanobacteria, they do not provide actual toxin readings, making them a supplemental weapon in a water utility manager&#8217;s arsenal to efficiently and economically adjust treatment to maintain drinking water safety.<\/p>\n<p>&#8220;Measuring toxin still requires a separate, fairly time-consuming test,&#8221; Bridgeman said. &#8220;Therefore, the fast optical measurements will be coordinated with slower chemical toxin measurements to provide a complete picture of what is happening in the lake water that is entering the water plant.&#8221;<\/p>\n<p>The device will be removed from the water treatment plant for analysis in October and then his team will study the results and potentially put it back in the plant next summer.<\/p>\n<p>Bridgeman&#8217;s device monitoring tests are one part of a larger, wide-ranging project funded by the U.S. Army Corps of Engineers that also includes faculty in the UToledo College of Engineering.<\/p>\n<p>Dr. Youngwoo Seo, professor of civil and environmental engineering and chemical engineering, leads the three-year project to improve water quality from the source to the tap.<\/p>\n<p>Some of the technology and techniques being tested by UToledo are new to water treatment plants in the western hemisphere.<\/p>\n<p>The project features two different parts working together:<\/p>\n<ul>\n<li>Advanced monitoring sensors and molecular genetic analyses to enhance early harmful algal bloom detection and real-time condition diagnostic capability; and<\/li>\n<li>Nature-inspired biological treatment methods coupled with algaecides to attack cyanobacteria and degrade toxins it produces.<\/li>\n<\/ul>\n<p>Dr. Dae-Wook Kang, assistant professor of civil and environmental engineering, leads a molecular approach to develop a robust detection method, and his analysis will help better understand what triggers the toxin gene production of cyanobacteria.<\/p>\n<p>Seo is focused on mitigation and the treatment method for toxin removal.
