According to Karel Ratering, Process Support & Data Analyst from the Nijhuis i-MONITORING team: "Every day we receive valuable information of the status of the installation. The installation is connected via our in-house NI-CONNECT router with our i-MONITORING center at Nijhuis Industries Headquarters in the Netherlands. The data we received includes wastewater parameters, energy consumption, chemical consumption and production of excess sludge. We analyze the data with daily reports generated, to see whether there are any notable changes in comparison to previous periods. We communicate and discuss the results with the client and in cases where necessary, we adjust the installation from our i-MONITORING center with remote control. With the wastewater of Azomures containing a large amount of total nitrogen, the installation is currently meeting and even exceeding the discharge limits with a total nitrogen reduction of more than 95%!

The client also communicates with us in case there is a change in the production process in the months to come. These changes in the production process have a major impact on the installation, because an additional amount or reduced amount of wastewater and/or pollution is produced. Since biological treatment plants are very sensitive to these changes, you need to find the correct balance between the excess sludge and return sludge to guarantee the best living conditions for this type of sludge. Based on the experienced level of wastewater treatment knowledge we have at Nijhuis, we can make the decision to adjust the settings of an installation correctly, to ensure a large-scale WWTP installation like Azomures is not only discharging 22.000 m3 per day of clean water but also optimizes their operational expenses. This setting change can include, for example, the dosing of chemicals or energy for the aeration of the biological treatment."
