Compare UV exposure with chlorine contact. Quartz-sleeved lamps and a separate baffled chemical-contact chamber illustrate two different dose measures.
• 3D scene parts: UV reactor / quartz sleeves; dosing pump / injection quill; baffled contact chamber; pathogen teaching markers; dose / residual monitor. • Controls: Disinfection method (UV, Chlorine); Water flow (50–300 m³/h); Effective contact volume (0.2–2 m³); UV irradiance (0.1–2 mW/cm²); UV transmission factor (0.2–1 fraction); Chlorine residual (0.1–2 mg/L). • Live readouts: Contact time (s); UV dose (mJ/cm²); Chlorine CT (mg·min/L); Illustrative log reduction (log₁₀). • Guided experiments: Low UV transmission; Higher flow. • Four tabs (visual laboratory, curves and measurements, experiments, learn and assess), a model-verification run, a timestamped event log and a trial report.
t = 3600V/Q UV dose = intensity × transmission × t CT = residual × t/60 Teaching LRV = 0.05 UV dose OR 0.5 CT
Fictional response coefficients for comparison only. No organism-specific claim, dose validation, hydraulic short circuiting, chlorine demand or potable-water determination. The selected method alone supplies the teaching LRV. Try the preset experiments, then compare the live readouts with the equations.
Dose and CT use different units..
