Dynamic modelling of wastewater treatment processes is used for dimensioning, optimization and operating of wastewater treatment plants. The novel modelling concepts enable us more precise prediction and has also been proven to optimise construction as well as operating costs.\u00a0<\/span><\/p>\n

Process modelling allows us to simulate the processes under different inflow conditions and relate it directly to the effluent quality, energy consumption or operational control parameters. Modelling of different scenarios enables us to calculate most favourable process volumes and make optimised choices for technology selection. This gives us the reliability to provide secure wastewater treatment process in adverse operating conditions.<\/p>\n

In addition to the responsibility to ensure the WWTP effluent discharge quality, the resource efficiency and energy recovery is also in focus. Whole plant modelling is a perfect tool to predict the optimal operating range for each treatment plant and allows us to avoid over-dimensioning and increased energy consumption. Modelling also allows to find the optimal chemical consumption (methanol, ferrous sulphate, acid or base) and to perform the most efficient aeration or control of any other technical equipment.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n

For most applications we have used the dynamic whole plant modelling approach where activated sludge or biofilm technology is integrated with the models of sludge treatment and anaerobic digestion. In addition, the model includes chemical phosphorus removal, precipitation reactions, pH changes, as well as models of sedimentation processes.<\/p>\n

Model calibration is crucial for any prediction model. \nTherefore we are dedicated to use the detailed laboratory analyses and wastewater fractionation for model development as well as for model calibration. Our qualified process engineers have long experience in performing the laboratory studies, interpretation and integration of the results for modelling purposes.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div><\/div>","protected":false},"excerpt":{"rendered":"Reoveepuhastite modelleerimine Reoveepuhastite dimensioneerimisel, optimeerimisel ja opereerimisel kasutame puhastusprotsessi modelleerimist, mis v\u00f5imaldab suuremat kokkuhoidu nii ehituskuludelt kui ka ekspluatatsioonikuludelt.\u00a0 Reoveepuhastusprotsesside modelleerimine v\u00f5imaldab erinevate reoveepuhasti sissevoolutingimuste juures simuleerida protsesside kulgu ning n\u00e4itab kui palju on sellest m\u00f5jutatud v\u00e4ljavoolu kvaliteet, energiakulu v\u00f5i...","protected":false},"author":1,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"_links":{"self":[{"href":"https:\/\/aquaconsult.ee\/en\/wp-json\/wp\/v2\/pages\/13580"}],"collection":[{"href":"https:\/\/aquaconsult.ee\/en\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/aquaconsult.ee\/en\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/aquaconsult.ee\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/aquaconsult.ee\/en\/wp-json\/wp\/v2\/comments?post=13580"}],"version-history":[{"count":9,"href":"https:\/\/aquaconsult.ee\/en\/wp-json\/wp\/v2\/pages\/13580\/revisions"}],"predecessor-version":[{"id":13622,"href":"https:\/\/aquaconsult.ee\/en\/wp-json\/wp\/v2\/pages\/13580\/revisions\/13622"}],"wp:attachment":[{"href":"https:\/\/aquaconsult.ee\/en\/wp-json\/wp\/v2\/media?parent=13580"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
