keep your lagoons and meet your targets

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.”
