Anaerobic digesters are used at Wastewater Treatment Works to minimise the solid waste needed to be removed from site, while reducing energy costs by means of on-site power generation from the biogas produced – lowering carbon emissions as part of the process.

In order to achieve the optimal bacterial reaction within a digester, sludge has to be present in the tank for an optimal period of time. While in the tank the sludge needs to be well mixed to ensure bacteria are available for the reaction to occur and to ensure homogeneity of reactive species and temperature.

MMI uses Computational Fluid Dynamics (CFD) to assess the residence time and degree of mixing by replicating dye trace studies which may be undertaken at a price that is competitive to on-site trials.
