version 2.1.6
Welcome to the eBooster™ Engineering Tool
This tool is provided by eBooster™ (Ecas4 Australia Pty Ltd) for engineering sizing and evaluation of electrochemical systems for active chlorine generation in drinking water and warm water loop applications. It models the electrochemical production of hypochlorous acid (HOCl) from chloride ions naturally present in source water — without the addition of chemical reagents.
System Estimator
Enter water quality parameters or load a water profile, then specify operating conditions to receive a recommended system configuration and operating current for your target chlorine dose.
Advanced Model
Analyse a specific operating point in detail. Set model, current, flow and water chemistry to obtain cell voltage, Faradaic efficiency, ohmic losses, outlet pH and scaling indices.
Please read carefully before proceeding
Model Limitations
This tool is designed for drinking water and warm water loop applications. The following limitations apply:

• Operating temperature range: 5°C to 45°C. Warm water loop mode is fixed at 43°C.
• Faradaic efficiency is estimated using a proprietary model with Arrhenius temperature correction. Results are indicative and may vary from field conditions.
• The Langelier Saturation Index (LSI) and electrode service life (ESL) are engineering estimates only and do not replace laboratory water analysis or on-site verification.
• The polarity inversion interval is a scaling-risk indicator only, not a maintenance schedule.
• Conductivity estimated from ionic composition assumes dilute solution behaviour.
• Results are only valid for the eBooster™ B250, B2k and B10k models.
• The tool does not account for fouling, ageing electrodes, variable feed water quality, or non-ideal hydraulic conditions. For applications outside this scope, or where regulatory compliance is required, contact eBooster directly.

Current efficiency
ηF calculated?Faradaic efficiency — fraction of current that produces Cl₂ rather than O₂. For drinking water: computed from [Cl⁻] and temperature using a calibrated kinetic model (typically 5–20%). For sea water: fixed at 95% (high salinity saturates the kinetic model).

Local electrode conditions
pH at the electrode surface estimated via Graetz-Lévêque diffusion layer model. These are local values — bulk outlet pH is shown above. Note: bulk pH change is typically very small due to bicarbonate buffering; larger shifts measured on collected samples may reflect CO₂ degassing during sampling rather than a true bulk pH change.
