Differents Water Treatment Type…VEOLIA have it
• The choice of water treatment technology will depend on the
water quality.
• But also, you have to do a great evaluation CAPEX, OPEX to be
sure of the final choice.
• With VEOLIA, we have most of the available technologies on the
market.
• Direct filtration
• Clarification + filtration
• Ultrafiltration
• Nanofiltration (not addressed today)

The AnoxKaldnes History
Prof. Ødegaard started research on Kaldnes MBBR Process
Anox founded at Lund University (Sweden), R&D
Kaldnes founded to commercialize the MBBR technology at the
Technical University of Trondeim (Norway)
First MBBR was sold – still operating with same media
Anox acquires Kaldnes to create AnoxKaldnes Group
VEOLIA acquires AnoxKaldnes Group
Today more than 700 major industrial / municipal systems in operation
in 52 different countries
MBBR Technology
o
The process is based on the biofilm principle. The core of the
process is biofilm carrier elements made from polyethylene .
o
The biofilm carrier elements are kept suspended and in
continuous movement by aeration.
o
The carriers are designed to provide a large protected
surface for the micro-organisms and good mass transfer.
o
Media material is made of virgin polyethylene with a density
similar to water (0.94 to 0.96 kg/L).

Water flows through the MBBR reactors
o
2 reactors in series for BOD removal (to achieve low BODsol)
o
3 reactors in series for BOD removal + nitrification
o
Can include a pre-denitrification reactor (with internal recycle from the last MBBR reactor)
o
Can also include a post-denitrification reactor, with an external carbon source dosage
o
Clarification downstream of the MBBR
o
No sludge recirculation
Pure MBBR application
o
THE most compact system for BOD removal only (no nitrification)
o
o
HRT of about 1-2h total in the MBBR reactors
MBBR reactors about 3 times larger when nitrification is required
o
Lower BOD loading rate
o
o
Larger BOD reactors
Addition of the nitrification reactor

o
o
o
o
Requires polymer (1 ppm) to meet 25 mg/l TSS
Very low settling velocity, 0,3 to 0,4 m/h @ average flow
Not very efficient… Compact MBBR + Very large clarifier…
Requires polymer (1 ppm) and some coagulant
Allows very high velocity (up to about 120 m/h)
Small FOOTPRINT
Spidflow DAF
o High-rate (high velocity) DAF system from Veolia (10 to 30 m3h)
o Chemical-free operation (most of the time)
o Thick sludge production (2-3%)

Conclusion
Can MBBR help increase lagoon capacity?
o
MBBR allows increase of BOD removal capacity without adding
new lagoons
o
o
o
MBBR could then be installed upstream or in-between the existing
lagoons
MBBR removes the soluble BOD

What about nitrification?
o
MBBR could be installed between lagoon 1 and 2, but…
o
o
o
Water is already quite cold (3-4°C in winter);
Some N-NH4 « release » in downstream lagoons because of solids digestion
Best location for nitrification: downstream of last lagoon!
o
o
Very cold water: 0,1°C in winter
R&D project with University of Ottawa
o
Nitrification rates remain significant even at that temperature
– HRT = 4-5 hours!
o
Effluent N-NH4 <5 mg/L possible all through winter
Effluent N-NH4 <1 mg/L in summer
o
No net solids production by the MBBR
o
– No need for downstream clarification!

Conclusion
HYBAS or IFAS – Say Goodbye to ammonia
o
HYBAS = Veolia trade name for IFAS
IFAS = Integrated Fixedfilm Activated Sludge
o
IFAS = Activated sludge with MBBR media added
o
Main goal: boost nitrification out of an activated sludge system
o
Normally MBBR media is only added in one section of the aeration
tank, near the end of the aeration tank
o
o
o
No soluble BOD reaches the MBBR media
Prevents competition between nitrifiers and heterotrophs
HYBAS or IFAS
o
Benefits
o
Nitrification can be acheived using low SRT
o
Reduced aeration tank volume
o
Robust nitrification, with biofilm more stable under stress conditions than
suspended growth only
o
More suitable for cold water nitrification
o
o
Nitrifiers get washed-out with suspended growth only
Biofilm remains inside the reactor even under cold water conditions
o
Allows denitrification
o
Still possible to do bioP

What is a MBR
A MBR is a Membrane BioReactor:
- It is an Activated Sludge system with a secondary clarifier
- The membranes system is the “perfect” secondary clarifier
101
What is a MBR
- The biological reactor:
• Operated in a same way as
activated sludge, with higher
sludge age
• The micro-organisms are
converting dissolved and
particulate organic matter into
biomass and gaseous waste.
• At 12 °C : SRT > 20 days and
MLSS : 10-18 g/l
- The clarification phase:
• Membranes, fabricated mainly
from organic polymers, are acting
like a physical barrier.
• At 20°C : Average Hydraulic Flux >
20 L/h/m2 of membrane

Membrane
The membrane is a selective physical barrier to :
- Keep all the activated sludge in the tank
• MLSS
• Bacteria
- Allow only soluble components through the membrane
• No solids in the effluent (TSS)
• No bacteria or virus (according to pore size)

Membrane types
Three main membranes Technologies are available in the market
Flat Sheet
Membranes
Hollow Fiber
Membranes
External Tubular
Membranes
106
Membrane types (backwash mode)
- Flat Sheet:
• Influent water is
stopped and the air is
scouring the solids,
achieving a
declogging
- Hollow Fiber:
• Effluent water is injected
in a reverse way
ensuring the unclogging
of the membranes.

111
Hollow fiber – one holding end (PURON)
The Puron technology differs in
maintenance needs because:
Membrane fibers are only fixed at the
lower end
- Membrane moves freely in the water
and filtrate as seaweed
- Upper ends of the tubes are sealed
- Cleaning of the membranes
is done by injection of air
into the center of the single
header bundles

General presentation of PMT
… more than 1,000 WWTP in 35 countries
… but impatient to install more of them
Operating Principle
Use of a natural phenomenon
In turning, the mill wheel
alternates immersion and
emersion phases,
which causes bacterial
film development...
… that we use for wastewater
treatment
126
Operating Principle
The bacteria colonize the
first discs
Not much pollution
Bacteria grow on the entire
surface of discs
A lot of pollution
exceeding of capacity limits
Additional disc line

Advantages of the process, quality of material
Evolution of the material
BUT
with porous
discs, the
pores got
clogged by
biological
fouling
Porous discs
BUT
with time the
honeycomb
discs
collapse on
each other
Honeycomb discs
- PMT discs are
smooth and
clog-free
- Bacteria in
excess naturally
remove from the
discs
Advantages of the process, quality of material
Evolution of the material
- Screws & tanks
structure are in
stainless steel
Inappropriate drive motor
- The weldingless
full shaft is in
chrome-plated
stainless steel
- The coupling
between the gear
motor and the shaft
is realised by an
elastic coupling

SPIDFLOW® – Dissolved Air Flottator
165
SPIDFLOW® vs Conventional DAF
•
Conventional DAF facts:
•
•
•
Need polymer dosing (+/- 1 ppm), in addition to coagulant
dosing
The clarification velocity is limited (10 to 15 m/hr)
Sludge production has a concentration around 2-3%
Musling
166
SPIDFLOW® – Advantages
•
3 specific zones:
•
•
•
•
•
•
•
•
•
•
Distribution (coagulant is added)
Injection (microbubbles are created)
Clarification (TSS separation by flottation)
High velocity clarification rate up to 45 m/hr
Compact design
TSS under 20 mg/L at the effluent
Can operate without polymer
Can also operate with polymer when higher performance
is required
Sludge production has a concentration around 2-3%
Available in prefab units
