  • Solubility in water: Complete

Packaging

  • 5 gallon pails
  • 55 gallon non-returnable plastic drums
  • 275 gallon totes

Safety and Handling

Store in cool, dry and well ventilated area. Keep containers closed. Wash contaminated clothes before re-use. Wash thoroughly after handling. For more information, see the Safety Data Sheet provided with this product.

Chemical Feeding and Control

Use potable water that is free of residual chlorine or other oxidizing agents to make the cleaning solution. The cleaning solution is prepared by addition of 17 lbs of AWC C-245 for every 100 gallons of water (~2 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 1 hour and then soaking the membranes for 30 minute  for a total cleaning time of 3–6 hours. AWC C-245 should be added as necessary to the cleaning solution to maintain the pH range of 2–3 throughout the entire cleaning process. Depending on severity of fouling, your AWC representative will recommend optimal cleaning
times.
