Abstract: A composition and method for the removal of biological fouling from wetted surfaces intermittently or continuously in contact with water is disclosed. The method includes the steps of preparing a cleaning composition of basic pH from a strong base and an active oxygen donor component, applying the composition to the surface to be cleaned, and after a selected residence time, removing any unreacted cleaning composition and all removed fouling by rinsing or flushing with water.
Abstract: A composition and method for cleaning surfaces having deposits, such as drink water tanks, supply water wells, water filter systems, and distributor water lines. The composition contains in combination a cleaning solution and a disinfectant, such as hydrogen peroxide or peracidic acid. The cleaning solution can includes hydrochloric acid and/or phosphoric acid in combination with inhibitors, dyes and water. The composition is applied to deposits which have formed on these surfaces.
