MaxBiogas workshop 2023

timako on 22. December 2023

In the beginning of December 2023, our project group and partners from Veas gathered at OsloMet to go through our achievements of this year. Tiina Komulainen summarized the project. Matthew Stanford presented the Demo webapp. the Per Ola Rønning and Bita Joudi presented the fatty acid analysis methods and results for 40 daily samples from Veas WRRF. Truls Ødegaard showed the results of the modeling and control (SIMS2023 article) and initial work on modeling using DHI’s West software. Sheik Tawfique Elahi presented his background and ideas for his master’s thesis were discussed.

ACIT master students visit Veas WRRF

timako on 22. December 2023

In the beginning of November 2023, first year ACIT robotics and control master students visited Veas WRRF. The aim of the visit was to see the biogas production plant of which the students have modeled and designed control strategies for during Fall semester 2023. Kjell Rune Jonassen and Hilde Johansen gave an insightful presentation of the biogas plant at Veas WRRF. During the site visit, we also took a look at the ABB washing robots that clean the membrane filters of the digestate.

Virtual sensors for effluent nutrient estimation – SIMS2023

timako on 22. December 2023

In September Tiina, Truls and Malik traveled to Västerås, Sweden, to present our recent research results in the Scandinavian Simulation Societys annual meeting SIMS2023. Master student Malik Baqeri presented his work on estimation of effluent nutrients applied to a novel biological wastewater treatment process at Hias WRRF, Norway. The conference paper describing the data pre-processing methods and development of three different model types for the effluent nutrient estimation can be found here: https://ecp.ep.liu.se/index.php/sims/article/view/778

MaxBiogas Web Simulation

masta6127 on 28. November 2023

The MaxBiogas Web Simulation (WIP and not yet viewable) is fairly simple to interact with. The user can modify two inputs, the heater and intake flowrate. Every real second represents 1 simulated day, and the simulation lasts for 60 real seconds. The daily biogas and temperature are recorded on the dynamic graph. Furthermore, the total produced biogas and wattage is shown below the input sliders. The goal is to modify the input to maximize biogas production while minimizing wattage used.
