N₂O Emissions prediction from wastewater

Enhance biological nutrient removal models with the new ASM2dMod extension, featuring nitrous oxide (N₂O) production pathways. This update integrates pathways from both autotrophic ammonium-oxidising and heterotrophic denitrifying microorganisms. The enhanced model allows for more accurate simulations of N₂O emissions, critical for CO₂ footprint quantification and determination of Scope 1 emissions. This capability also makes it easier for researchers and engineers to understand and mitigate N₂O production in wastewater treatment processes, paving the way for more sustainable operations.

Enhanced energy production estimates

MIKE 2024 Update 1 also includes new algebraic models for estimating energy production from photovoltaic panels and wind turbines, tailored to your project’s geometry and local conditions. This latest update incorporates essential energy production methods into our cost calculator model, enabling a comprehensive plant-wide energy balance. With this integration, you can efficiently evaluate the potential energy output and associated costs, ensuring optimised operational planning and enhanced sustainability of energy projects.

Updated IoT integration in new sample project

WEST also includes a new sample project demonstrating the capabilities of the Influent Fractionator designed for the ASM2dMod. This powerful tool is essential for preparing dynamic influent files for wastewater treatment plant modelling. By using a dynamic regression technique, it transforms a collection of time series measurements into corresponding model components, accommodating varying time schedules. This update enhances the accuracy and flexibility of influent modelling, making it indispensable for optimising WWTP operations.

Evaluate the performance of a new or an existing WWTP through pre-defined and custom indicators. Compare design alternatives for new WWTPs under dynamic conditions with respect to effluent quality, investment and operational costs. Implement plant-wide models by integrating multiple layers (water line, sludge line, energy, control) to holistically evaluate and optimise plant operations and facilitate the transition from treatment plants to resource recovery facilities. Identify optimal operational and control strategies and instruct facility staff on new ways of operating their WWTP. Benefit from the Advanced Experiments toolkit to achieve these outcomes faster.

Take advantage of the full openness and accessibility of the WEST model and block libraries to develop and implement custom models and unit operations that include non-standard processes and components. Build fully customisable control systems to fit plant-specific nuances in operation and control. Benefit from the user-friendliness of Model Editor and Block Editor for swift implementation, even during project execution.

Perform long-term and complex simulations of integrated systems including catchments, collection systems and recipients (watersheds, rivers) in a less computationally intensive manner. Deliver more accurate predictions of inflows and solids loading to WWTPs during both dry and wet weather conditions using state-of-the-art rainfall-derived infiltration models and the new Particle Size Velocity Distribution (PSVD) model. Evaluate the impact of CSOs on recipient quality with a simplified catchment model for influent generation. Incorporate a variety of sensors and controllers to allow for real-time simulation and process optimisation at a system-wide scale.

WWTPs are known to be large consumers of energy (power and heat) produce large amounts of greenhouse gases (e.g. N2O). WEST users can accurately perform energy balances, tracking energy use from aeration systems, pumps, mixers and sludge pre-heating systems as well as recovery from biogas and heat pumps. WEST also allows to track a variety of greenhouse gas sources, both direct and indirect, using state-of-the-art models. Compare operational strategies and identify the most effective sustainability solution to achieve energy and carbon neutrality.
