Giardia cyst / Cryptosporidium oocyst
Captured at barrier
UV lamp
Helminth eggs and protozoan cysts — Giardia cysts and Cryptosporidium oocysts chief among them — survive ordinary chlorination and are a real driver of waterborne outbreaks, which is why treatment plants rely on a multi-barrier approach instead of a single kill step. This 2D top-down simulator renders the same treatment train — coagulation/flocculation, rapid sand filtration and UV disinfection — as the 3D version, letting you tune the coagulant dose, filter media grain size and UV lamp dose while watching individual (oo)cysts get captured at each barrier. Drag to pan across the train and scroll to zoom into any zone. Live readouts track the combined log-reduction value, the resulting effluent concentration and whether the plant clears the standard 3-log Giardia/Cryptosporidium removal-or-inactivation benchmark.
