The application of ADM/ASM interface in sumo wide plant model

Abstract

Sumo is an innovative and most versatile wastewater simulation package on the market. The simulator is capable of modelling treatment plants of unlimited complexity, focusing largely on BOD, nitrogen and phosphorus removal; with digester, side streams, IFAS and MBBR, SBRs, trickling filters, primary and final settling, thickeners, centrifuges being process units typically found in Sumo which are used in municipal and industrial treatment plants. The model interface has numerous models including ASM (AM1, ASM2D, ASM2D_TUD, ASM3, and ASM3_BioP), Barker_Dold, and BUCTPHO plus. Sumo models can be run through several different interfaces. Though, ADM1 model is perhaps the most extensively applied for the simulation of anaerobic processes, it is not included in Sumo which incorporates a sludge model because of its complexity and ongoing modification. Simulation can still be achieved by simply interfacing ADM1 and ASM1 models by converting ADM1 state variables to ASM1 variables for use in Sumo.
