The cleaning solution should be prepared using potable water that is free of residual chlorine or other oxidizing agents. Add 2 gallons of AWC C-237 to every 100 gallons of water (2 % solution). Adjust the pH in the range 10–11. Recirculate the cleaning solution throughout the system, after redirecting the first 20% of the solution to drain. Do not exceed 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 15 minutes and then soaking the membranes for 15 minutes. This should be repeated as many times as necessary. The pH range should be monitored periodically throughout the cleaning. When pH drops below the desired range, it should be adjusted by adding more AWC C-237. Optimal iron removal occurs at pH of 8.5 – 10.5.
