Wasting Practices
As wastewater conditions (influent flow and BOD loading) change daily,
wasting should not be recalculated and readjusted based on daily
values, for risk of WAS GPD going drastically up and down creating
process instability.
Instead, wasting calculations should incorporate 7-to-10-day averages
for influent flow, MLVSS concentration, WAS concentration to serve as a
buffer and help smooth out daily wasting flows.
