BIOLOGY
To avoid nutrient pollution from incomplete biological treatment, WWTPs often have to meet these effluent requirements
Discharge limits
Biggest challenge or limitation to instruments in wastewater
Bio-fouling
Physical/Mechanical (Primary), Biological (Secondary), Chemical (Tertiary)
This test represents the amount of oxygen used by bacteria while they consume organic matter
5-day BOD (Biochemical Oxygen Demand)
ISE and 'Wet chemistry analyser' are two ways of measuring this parameter
Ammonia
Quantity and Quality are two highly variable unkowns during this challenging-to-treat wastewater phenomenon
Wet weather- influent and infiltration
This faster proxy measure is used to estimate organic loading and aeration needs through manual sampling
COD (Chemical oxygen demand)
There are 13 steps to this pH sensor process
calibration
VFA overloading is a risk of this growing bio-gas boosting approach in AD
F.O.G. additions in Co-digestion
When D.O. reads unusually high with normal aeration levels, what can that mean about influent composition
TOXICITY - something toxic is killing biomass or impeding treatment
The recommended calibration interval of an ORP sensor
Every Day
A bigger field, one more player, and this are the main differences between NFL and CFL football
the number of Downs in a posession (3 in CFL)
An upset of Food to Mass ratio because of inaccurate organic loading information can lead to these headaches for operators (name 2)
Septicity, H2S, Foaming, bulking, settlability problems, dewatering issues, costly over- or under-aeration
This instrument-guided process can account for 50-60% of a plants operations costs
Aeration
WHY ARE THE KITKATS DIFFERENT?!?!?!
Different manufacturers!!
