Accounting for up to 50% of your facility’s water use, a cooling tower consumes water through evaporation, bleed off, drift and make-up water. Ensuring these processes are efficient will minimise water loss.
Watch this video to find out how your cooling tower uses water in 4 key areas:
- Evaporation – general guideline for estimating the rate of evaporation is 12 litres/minute per 100 tons of cooling load
- Bleed off – intentional release of some of the circulating water to remove suspended and dissolved solids
- Drift – water loss in the form of mist, driven by the air draft of the tower
- Make-up water – water that needs to be added (made up) to the cooling tower to replace water lost through evaporation, bleed off and drift.

Watch this video to find out how to optimise your cooling tower through 3 key areas:
- Cycles of concentration – how to optimise these for best performance
- Own the system – ensure your operation or site managers carry out maintenance checks and monitor water use
- Management support – ensure the management team is accountable and understand your water use objectives and targets
