This powerpoint presentation begins by providing a brief overview of the City of Thornton's water supply and the selection of the treatment option of biological denitrification. The project overview includes: pilot testing of three biological processes
for the removal of nitrate as pretreatment
in drinking water;
Water Research Foundation Project No. 4202,
total project cost - $596K, the
Tailored Collaboration Program conducted a seven month pilot study;
highest nitrate concentrations typically
during cold water conditions;
influent nitrate spiked to ~10 mg/L NO<sub>3</sub>-N;
goal of 80% nitrate removal (< 2 mg/L); and, methanol selected as preferred carbon
source for piloting. Pilot objectives were to: determine process performance in warm and
cold water temperatures,
specifically nitrate removal;
determine design basis for full-scale
implementation;
evaluate startup and ability for intermittent
operation;
optimize and evaluate operation; and, investigate effects of fluctuating raw water
conditions. Includes tables.
