Brine Volume and Mass Calculator
The brine flow belongs to the plant mass balance, so this calculation takes the concentrate flow you already have rather than inventing a recovery to produce one. Over the operating hours you state, it gives the annual volume, the daily volume and the salt mass inside it — which is the physical disposal case. A concentration limit is a permit value for a specific receiving water, so it is optional and never assumed, and arithmetic against it produces a number rather than an authorisation.
Design parameters
The brine flow, its concentration and the operating hours are required. The permit limit and the receiving water flow go together — one without the other is not a dilution check.
Basis and limits
- No compliance verdict is issued. Whether this discharge is permitted depends on the receiving water body, the permit conditions, the outfall, and the constituents this calculation does not characterise.
- The annual volume scales directly with the operating hours you supply, so a plant promised at 90% availability and actually run at 60% produces far less than a full-year figure.
- Temperature, chlorine residual, boron and every other constituent are outside this calculation. The brine is characterised by TDS because a salt mass calculation needs TDS, not because TDS is sufficient.
- The receiving water is taken as fresh at 0 TDS in the dilution arithmetic, which over-states the dilution required.
