Activated Sludge Wastewater Treatment: Cross-Section (2D)

This is the 2D cross-section counterpart to the 3D activated-sludge simulator: the same continuously-stirred-reactor process — amber pollutant particles drifting into an aeration zone and being consumed by brown biomass flocs at a rate set by dissolved oxygen and biomass concentration, while settled sludge either recycles back to sustain the reactor (RAS) or is wasted — viewed as a true side-on slice through the two-tank plant. Drag to pan and scroll to zoom across the aeration tank, the divider gap and the clarifier's settling hopper. Four real process controls — influent flow, MLSS, aeration intensity and recycle ratio — drive the same CSTR mass-balance equation used to design real plants, with effluent BOD, removal efficiency, F/M ratio and hydraulic retention time updating live as you tune them.
