Chlorination Procedure

Biocide Application Frequency

Biocide

  • If possible chlorinate during cooler, night-time hours or low load conditions to increase solubility/retention time and decrease de-gassing.
  • Increase blow down in order to decrease cycles to near the lower limit of control range.
  • Increase H2SO4 feed rate to decrease the pH to near the lower limit of control range.
    • Note : Do not apply oxidizing biocides when pH is below the lower control range - excess corrosion can result.
      Close blow down.
  • Feed chlorine (or bleach) to reach a measurable free chlorine residual of 0.2 ppm.
    • Note : Excessive levels of free chlorine will result in elevated corrosion of mild steel and copper alloys.
  • Maintain free chlorine residual for a minimum of two (2) hours.
  • Resume normal blow down being careful not to exceed discharge limits in the plant out fall.
  • Resume normal pH control.
