The purpose of this research was to evaluate different pretreatment alternatives for microbial
removal efficacy using a seasonally brackish surface water. The following three pretreatment
systems were evaluated:
the Super Pulsator (SuperP) blanket clarifier followed by dual media gravity filtration;
the Actiflo micro-sand ballasted clarifier followed by dual media gravity filtration; and,
the Zenon immersed ultra-filter.
From September through October 2002, microbial challenge studies were conducted on these
pretreatment systems. The challenges used MS-2 phages, PRD-1 phages, and 3-micron beads to
compare the removal efficacy of the pretreatment systems. Further, background fecal and total
coliform removals were evaluated. Includes tables.
