The increased passage of particles through granular media filters immediately following
backwashing is commonly known as the filter ripening period, and several different strategies have
been developed through the years to reduce the impact of this vulnerable period of the filter cycle
on filtered water quality. A new backwashing strategy intended for reducing particle passage into
the effluent water, the extended terminal subfluidization wash (ETSW), has been developed and
evaluated 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 results
and relevant information from the literature. The numerous mechanisms and stages of the FRS
have been described in detail and may benefit future attempts to optimize this portion of the
filtration cycle and/or to model filter performance throughout an entire filter run. Includes 22 references, tables, figures.
