Historically, water authorities would only know what was being discharged into the environment after the fact, through on-site or lab testing. But [Endress+Hauser](https://www.au.endress.com/en) Victorian State Manager Steve Street said today’s technology makes the monitoring process more reliable, accurate and timely. “With the previous generation of technology, you would only know retrospectively what was being released, by measuring a collection of samples taken throughout a whole day or week,” Street said. “There was no opportunity to control what was being discharged; the results from the testing would come in too late to change the process. “With the latest technology you are now getting data in real time, which means you can stop the plant from discharging if you’re in breach.” Along with ensuring the discharge is within the correct limits, tools like [Endress+Hauser’s ammonium analyser](https://www.au.endress.com/en/field-instruments-overview/liquid-analysis-product-overview/ammonium-analyzer-ca80am) can also help optimise operations and save energy.  The accuracy of the analyser – it can measure ammonium levels with 0.1mg/l accuracy – means operators can control the amount of dissolved oxygen needed in an aeration tank based on the ammonium load. “Before, a treatment plant might only monitor dissolved oxygen and run their blowers independently of ammonium levels,” Street said. “But when you accurately know the ammonium level you can control the process such that it is marginally below your Environment Protection Authority limit.  "For example, if the plant has a discharge limit of 1mg/l, and you’re discharging at 0.2mg/l, you’re wasting energy in aeration.” # Low-maintenance measurement   Street said the latest generation of analysers are designed to be low maintenance, which makes them ideal for regional and remote locations. This includes an inbuilt cooling module that keeps temperatures down even in hot locations and increases the lifetime of the reagents within them. “Usually with reagent based analysers you would have to change the reagents every three to four weeks,” Street said. “The maintenance on the latest analysers can be pushed out to every three months … This means you can run advanced nutrient analysis even on a regional or unmanned site.” The technology is also getting smarter all the time with the industrial internet of things (IIoT), Street said. This means an analyser in a remote location can send an alert for high/low measurement levels or if it is down or due for maintenance.  “As the tools get more accurate and less maintenance intensive, it’s becoming more feasible to put more analysers on outlets and discharge points,” Street said.  “At one of the treatment plants we’re working with, the end goal is for the plant to be unmanned. “Upgrading to the latest generation of nutrient analysers provides a wide range of benefits, ranging from being able to control your process to avoid incidents to reducing both electricity and maintenance costs. These new analysers can be integrated into an IIoT solution providing further benefits.” [ Sponsored ](https://www.awa.asn.au/resources/latest-news/tag/sponsored) Share [![email icon](https://www.awa.asn.au/hubfs/website-assets-2021/icons/icon-dark-sandstone-email.svg "email icon") ](mailto:?subject=The%20next%20generation%20nutrient%20analysers%20helping%20optimise%20wastewater%20treatment&body=Check%20out%20https://www.awa.asn.au/resources/latest-news/sponsored/the-next-generation-nutrient-analysers-helping-optimise-wastewater-treatment) [![facebook-icon](https://www.awa.asn.au/hubfs/website-assets-2021/icons/icon-dark-sandstone-facebook.svg "facebook icon") ](https://www.facebook.com/sharer/sharer.php?u=https://www.awa.asn.au/resources/latest-news/sponsored/the-next-generation-nutrient-analysers-helping-optimise-wastewater-treatment) [![LinkedIn icon](https://www.awa.asn.au/hubfs/website-assets-2021/icons/icon-dark-sandstone-linkedin.svg "LinkedIn icon") ](https://www.linkedin.com/shareArticle?mini=true&url=https://www.awa.asn.au/resources/latest-news/sponsored/the-next-generation-nutrient-analysers-helping-optimise-wastewater-treatment) [![Twitter icon](https://www.awa.asn.au/hubfs/website-assets-2021/icons/icon-dark-sandstone-twitter.svg "Twitter icon") ](https://twitter.com/home?status=https://www.awa.asn.au/resources/latest-news/sponsored/the-next-generation-nutrient-analysers-helping-optimise-wastewater-treatment) ## RELATED NEWS [![](https://www.awa.asn.au/hs-fs/hubfs/Tessele2.jpeg?width=352&name=Tessele2.jpeg) ](https://www.awa.asn.au/resources/latest-news/fabiana-tessele-why-the-conditions-behind-innovation-need-a-rethink) ### [ Fabiana Tessele: why the conditions behind innovation need a rethink ](https://www.awa.asn.au/resources/latest-news/fabiana-tessele-why-the-conditions-behind-innovation-need-a-rethink) Cecilia Harris The water community has long focused on advancing technology to solve increasingly complex challenges, but according to Tessele… [ Read Full Paper ](https://www.awa.asn.au/resources/latest-news/fabiana-tessele-why-the-conditions-behind-innovation-need-a-rethink) [![](https://www.awa.asn.au/hs-fs/hubfs/Imported_Blog_Media/Marc_Sneddon.jpg?width=352&name=Marc_Sneddon.jpg) ](https://www.awa.asn.au/resources/latest-news/business/workplace/meet-the-new-sa-member-engagement-manager-marc-sneddon) ### [ Meet the new SA Member Engagement Manager: Marc Sneddon ](https://www.awa.asn.au/resources/latest-news/business/workplace/meet-the-new-sa-member-engagement-manager-marc-sneddon) Water Source The Australian Water Association’s South Australian Branch sat down with the new SA Engagement Manager Marc Sneddon to find out… [ Read Full Paper ](https://www.awa.asn.au/resources/latest-news/business/workplace/meet-the-new-sa-member-engagement-manager-marc-sneddon) [![](https://www.awa.asn.au/hs-fs/hubfs/bushfire-4772240_1280.jpg?width=352&name=bushfire-4772240_1280.jpg) ](https://www.awa.asn.au/resources/latest-news/nsw-councils-pilot-weather-simulation-technology-for-disaster-preparedness) ### [ NSW councils pilot weather simulation technology for disaster preparedness ](https://www.awa.asn.au/resources/latest-news/nsw-councils-pilot-weather-simulation-technology-for-disaster-preparedness) Water Source As the frequency and intensity of extreme weather events increase due to climate change, councils across NSW are piloting an… [ Read Full Paper ](https://www.awa.asn.au/resources/latest-news/nsw-councils-pilot-weather-simulation-technology-for-disaster-preparedness) Advertising --- ### Subscribe to our newsletters Sign up to get the latest news and insights from us Advertising --- ![white arrow pointing upwards](https://www.awa.asn.au/hubfs/website-assets-2021/icons/awa-white-arrow-up.svg) Top [![Footer-logo-02](https://www.awa.asn.au/hubfs/Footer-logo-02.svg) ](https://www.awa.asn.au/) The **Australian Water Association** acknowledges the Traditional Custodians across Australia, where we live, work and play, for their deep connection to our precious waters and land.
