General Review on Characteristics of Accumulation and Release of Trace Metal Elements within Aluminum-Containing Scales in Pipes of Drinking Water Distribution Network
The accumulation of trace metal elements on aluminum containing sediments,the effects of variations of raw water quality,chemical reagents,solution pH and drinking water flow condition on stability of aluminum containing sediments and the release of trace metal elements were discussed.In order to decrease the release of trace metal elements,and to ensure the pipe operation and human safety,water quality adjustment was suggested to avoid aluminum containing sediments formation in drinking distribution system.The maximum amounts of accumulation of common trace metal elements were given.Future trends of development in this field were also proposed.
