AI HYDRAULIC RECOMMENDATIONAuto Recommend evaluated all four supported WDS models and selected the smallest compatible model, WDS2000X. It can supply the requested dissolved ozone concentration at the calculated inlet flow with 11% generator safety margin.Total estimated treated-water basis: 1,920 L/day. Pressure, temperature and water quality apply visible estimated factors to MTE.
Each stage receives fresh ozonated water, follows an independent decay profile, and resets to zero at drain. Exposure values are engineering information, not acceptance criteria.

PROCESS ENGINEERING RECOMMENDATIONCalculated dissolved ozone is below the Hospital OPL BES Design Standard. Consider reducing fill flow, increasing generator capacity, or reducing concurrent demand.Every drain stops the current stage exposure, resets concentration to zero, and starts the next stage as a new exposure event.
OZONE DECAY TIMELINE
Actual dissolved ozone and BES Design Standard
Ozone exposure continues through wet contact while the generator is OFF. Drain resets concentration before the next stage.

04 / MAINTENANCE & RUNTIME
Fill-only generator duty
The generator clock advances only while an inlet valve is open. Wash, soak and agitation contact time never adds EOG runtime.
