ECC 3555A and ECC 3555B are added to deionized water when cleaning an ultra-filtration unit. Typically, one drum of each component is mixed with enough deionized water to produce 1,000 gallons of cleaner. The A and B components should never be mixed together and never be used for cleaning without first diluting with water. For excessively fouled membranes, a maximum of two drums of each component diluted to 1,000 gallons with water should be used. |
