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.
Cleaning solution should be prepared using potable water free of residual chlorine or other oxidizing agents. Solution should consist of 9–18 lbs of AWC C-226 for every 100 gallons of water (1 – 2 % by wt. solution). Adjust pH between 10–11 by adding more AWC C-226 if necessary. Circulate the cleaning solution throughout the system without exceeding pressures/flow rates recommended by the membrane manufacturer. Cleaning efficacy can be improved by heating the cleaning solution and alternately circulating the solution for 15 min and then soaking the membranes for 15 min. Repeat as many times as necessary. Add AWC C-226 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.
