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. The solution is prepared by adding 18 lbs of AWC C-230 for every 100 gallons of water (2 % by wt. 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 and alternately circulating the solution for 60 minutes and then soaking the membranes for 30- 60 minutes for a total cleaning time of 4-6 hours. AWC C-230 should be added as necessary to the cleaning solution to maintain the pH range of 10-11 throughout the entire cleaning process. Depending on severity of fouling, your AWC representative will recommend optimal cleaning times.
