The objectives of this powerpoint presentation were: to present representative results from lab and field
studies conducted to evaluate the effect of oxidants
on particle removal in granular media filters,
recognizing the role of biology/photosynthetic activity; and,
to present follow-up work conducted at the
Onondaga County Water Authority, including
unintended consequences of switching pre-oxidants. The four oxidants studied were
ozone,
chlorine,
chlorine dioxide, and
potassium permanganate. Results of the field studies are provided, along with lab filtration studies and design criteria. A case study is provided of the Onondaga County Water Authority. The goals of the AwwaRF Project 2725, Using Oxidants to Enhance Filter Performance, are listed and include: to determine the conditions under which oxidants can be used to enhance the removal of particles by coagulation and filtration; to better understand the mechanisms of oxidant-enhanced
particle removal;
to determine the conditions under which it will
occur; and, to develop design and operating criteria to
promote oxidant-enhanced particle removal.
