Keep Your Lagoons and Meet Your Targets
Chris Howorth P.Eng.
Many things to like
• Simple O&M
• Sludge management
But they have limitations
• Large footprint
• Performance limitations
Lagoons Are Great! But…..
WSER:
Unionized ammonia <1.25 mg/L
Non-toxic effluent
Target TAN <~5 mg/L
New Regulations Bring New Challenges
Nitrifiers Prefer Summer!
Keep what you’ve already got
As simple as a lagoon
Compact
Cost effective
Robust
Adaptable
What Would Good Look Like?
Hug, don’t swim
Same process principle
Not new
Various configurations
(Attached) Growth is Good
Where To Put It?
BOD, TSSAmmonia
What Is It?
BOD, TSSAmmonia
Fits all lagoon types
Handles TSS/algae
Lagoon
In a Box
MBBR Technology is a Great Fit
“Moving Bed Biofilm Reactor”
Simple: flow-through, self-adapting
Compact: high rate process
Robust: hard to break, handles TSS
Flexible/Adaptable: ammonia, BOD, TN
AnoxK™ 5: PSA = 800 m2/m3
‘Carriers’ Provide Protected Surface Area
Sieves Keep Carriers in the Basin
Air Grids Mix and Provide Oxygen
Veolia’s AnoxKaldnes group invented MBBR
First commercial installation in 1989
>1200 Veolia MBBR plants globally
>30 plants in Canada (since 2005)
MBBR is Well Proven Technology

Future-proof
O
● As simple or better to operate than an aerated lagoon
● Automatically adapts (load, temperature, flow)
● Resists toxic shocks
● Tolerates very high hydraulic peaks
&M● Zero ‘in-basin’ maintenance
● Blower(s), DO Probe(s), flow meter(s)
“…easier to operate than the lagoons,
and with much better performance.”
