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.
HYDRAULIC CALCULATION BASIS

Transparent engineering sequence

01Peak Flow

8.0 L/min × 1 × 60 = 480 LPH

02Dissolved Demand

480 LPH × 0.30 mg/L = 144.0 mg/h

03Generator Demand

144.0 ÷ 80.0% = 180.0 mg/h

04Capacity Check

200 − 180.0 = 20.0 mg/h

Effective MTE = WDS 80% product parameter × pressure factor 1.00 × temperature factor 1.00 × water-quality factor 1.00. Maximum target flow = min(2,300 LPH rated flow, 533 LPH ozone-limited flow).

02 / OZONE PROCESS PERFORMANCE

Stage concentration and decay

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.

Initial Dissolved Ozone0.333 mg/LBelow BES Design Standard · fresh concentration
Estimated Main Wash Concentration0.146 mg/LEstimated concentration at Main Wash drain
Estimated Final Rinse Concentration0.253 mg/LEstimated concentration at Final Rinse drain
Program Contact Time30.0 minWash and agitation contact; fill time excluded
Estimated Ozone Exposure9.44 mg·min/LCumulative sum of independent stage exposures
Ozone Decay Profile0.055 min⁻¹Exponential engineering decay coefficient
PROCESS ENGINEERING RECOMMENDATIONCalculated dissolved ozone is below the Hotel 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.
