Chemical Feeding and Control

  • The cleaning solution should be prepared using RO permeate or softened water that is free of residual chlorine or other oxidizing agents. Use a 2% AWC C-239 by weight solution. 
  • The cleaning solution is then circulated throughout the system without exceeding pressures, temperatures and flow rates recommended by the membrane manufacturer. 
  • Cleaning efficacy can be further improved by heating the cleaning solution 
  • AWC C-239 should be added as necessary to the cleaning solution to maintain the pH range throughout the entire cleaning process. Depending on severity of fouling, your Membrane Works representative will recommend optimal cleaning times.
