Ontario Pipeline - Fall 2018 - 21

PREVENTING THE FORMATION
OF DBPS IS A MULTI-FACETED
ISSUE FOR DRINKING WATER
UTILITIES, WITH A VARIETY
OF STRATEGIES BEING
DEVELOPED FOR BOTH
GENERAL TREATMENT AND
SPECIFIC PLANT/SOURCE
CONDITIONS. EACH FACILITY
AND WATER SOURCE IS
DIFFERENT, THEREFORE
NO ONE STRATEGY CAN BE
APPLIED ACROSS THE BOARD,
AND OFTEN UTILITIES ARE
ENCOURAGED BY THEIR
LOCAL AUTHORITY TO HAVE
A UNIQUE MONITORING
PLAN DEVELOPED.
successfully capture/detect any event detected
by UV254 or TOC, and suggests that peCOD can
capture/detect a greater fraction of the NOM than
the other parameters for certain events. The next
stage of this project for the Massachusetts Utility
is to utilize a THM analyzer alongside the online
analyzers monitoring source water, which mimics
disinfection to form then measure THM DBPs. The
utility will develop correlations and trends for each
parameter, as well as combinations of parameters,
to actual DBP formation. The implementation of
the peCOD parameter has already given the utility
a barrier of protection, in that the operators constantly check the value to get an idea of the incoming
NOM to the plant. As more data gets collected, the
operators will continue to establish connections
between measured values/behaviour and real plant
decisions, improving their operation efficiency leading to reductions in operating cost.
Justin Dickerman, MANTECH Quality Control and
Research Development, has been employed at
MANTECH since December 2016 after attaining a
Bachelor of Engineering from the University of Guelph
in the discipline of Environmental Engineering. Justin
has performed numerous installs of peCOD systems,
while also providing technical support and training
for customers. Justin is also currently involved in multiple peCOD-related research projects with MANTECH's
academic partners, studying the application of peCOD
for surface water monitoring, event detection, treatment optimization, advanced treatment monitoring,
and prediction of the formation of DBPs in drinking
water treatment.
