FlowMac was used in a main study for a rebuild of an existing effluent treatment plan.
With FlowMac we made a complete model of all different treatment stages: preflotation, buffers, presedimentation, anaerobic treatment, aerobic treatment, secondary sedimentation, tertiary flotation, sludge handling.
It has been developed a new FlowMac block for anaerobic treatment where the user can specify COD-reduction and the COD is converted to raw biogas (methane, CO2 and H2S).
Mill data for incoming COD, suspended solids and flow data can be fed into the model to evaluate overall COD reduction, biogas production and alternative operating scenarios.
