This slide presentation outlines a pilot study at the Mohawk Valley Water Authority (MVWA) that evaluated chloramines as a method for nitrification control. Objectives of the pilot study included: identify a robust nitrification control
strategy so that MVWA can implement
chloramines if it chooses;
evaluate several nitrification control
approaches on the pilot scale using
finished water from Hinckley WTP;
demonstrate to the State that nitrification
can be controlled/prevented in the MVWA
system; and, provide recommendations on integrating
most suitable nitrification strategy into
chloramines system design. The pilot study methods included: four independent treatment trains representing
Hinckley WTP finished water quality and employing
different nitrification control techniques
(water carboys with test solutions,
followed by a glass bead bio-reactor,
then 400 feet of flexible black irrigation
pipe-plug flow reactor);
sampling 1-2x per week;
seeding of glass bead reactor with Ammonia Oxidizing Bacteria (AOB);
analyzed for key parameters in MVWA lab; and,
use of contract lab for chlorite.
