Full Description

The increased passage of particles through granular media filters immediately followingbackwashing is commonly known as the filter ripening period, and several different strategies havebeen developed through the years to reduce the impact of this vulnerable period of the filter cycleon filtered water quality. A new backwashing strategy intended for reducing particle passage intothe effluent water, the extended terminal subfluidization wash (ETSW), has been developed andevaluated on both pilot-scale and plant-scale filters in this research. The filter ripening sequence(FRS) has been described with new clarity based on the interpretation of these experimental resultsand relevant information from the literature. The numerous mechanisms and stages of the FRShave been described in detail and may benefit future attempts to optimize this portion of thefiltration cycle and/or to model filter performance throughout an entire filter run. Includes 22 references, tables, figures.
