A virtual autodesk-simulink reference plant for wastewater treatment

Abstract

This work developed a reconfigurable Simulink-Autodesk Inventor similitude of multistage processes involved in medium scale urban runoff wastewater treatment plants WTPs. The re-enactment approach for wastewater handling is modelled with detailed attention to its fundamental stages. Parameter identification techniques were used for stream improvement processes to realize a flexible and practicable virtual plant. Simulation results were obtained for wastewater treatment in the grit chamber, activated charcoal, coagulation and sedimentation basins respectively. Reduction in sand concentration and the volumetric flow rate of feedstock to effluent are 𝟕𝟓𝟎𝒈/𝒍 to 𝟎.𝟎𝟑𝟕𝟒𝟓𝒈/𝒍 and 𝟒𝟎𝟎𝒍/𝒔 to 𝟏𝟐𝟎𝒍/𝒔 respectively. The corresponding sedimentation speed is recorded as 𝟎.𝟎𝟓𝟕𝟏𝟖𝒎𝒎/𝒔. The grit filters dry matter from 0.6g/l to 0.048720g/l; to realize 92% reduction of original dry matter in the feedstock. Thus, a prototype framework for input-process-output response analysis of an efficient wastewater treatment plant is developed to guide the design and implementation of new WTPs as well as optimize operations in existing facilities.Keywords: Wastewater, Treatment Plant, Matlab Simulink, Autodesk Inventor
