Cooling Water

Cooling Towers work on evaporation, drawing in environmental air and expelling heat in the form of water vapour.  Although the water is dosed, CET Group employs measures to avoid microbiological contamination to:

  • Prevent pockets / dead legs that allow growth and become bacterial feeding sites;
  • Sluice and expel debris from basins and flat surfaces within towers to remove sludge that protects organisms from dosed chemicals;
  • Ensure constant movement of water at velocity in piping network even when process cooling is not required;
  • Flush lines at start up;
  • Ensure minimum flows are achieved to keep evaporation surfaces scrubbed with velocity inside towers.

Closed loop systems are designed to minimise pockets, allow regular dosing and move at velocity to ensure pockets are replenished.
