BIOLOGICAL TREATMENT OF EFFLUENTS
WITH HIGH CONCENTRATIONS
OF AMMONIA
WASTEWATER
REMOVAL OF NITROGEN GENERATED BY
ANAEROBIC DIGESTION OF BIOSOLIDS
PERFORMANCE AND SAVINGS
SUSTAINABLE DEVELOPMENT
Cost-effective treatment of stream with
high-loads of ammonia
Reduction of resources (energy,
chemicals) used
INNOVATION
DEAMMONIFICATION ALLOWS THE TREATMENT OF
CONCENTRATED AMMONIA GENERATED BY ANAEROBIC
DIGESTION OF SLUDGE IN THE SIDE STREAM OF THE
PLANT– LIMITING THE IMPACT OF DIGESTION
ON THE MAIN WATER TREATMENT LINE.

less air needed compared to
conventional activated sludge treatment.
Cleargreen™ (for Cyclic Low Energy Ammonium Removal)
augments anaerobic treatment of biosolids
(biological, primary, co-digestion)
by removing the nitrogen
overload.
Cleargreen™ TECHNOLOGY...
ADVANTAGES
Feed, aeration and deammonification phases are divided into
sub-cycles and adapt in duration and intensity according to the
characteristics of the effluent to be treated. The deammonification
process uses Anammox bacteria, naturally present in the environment. Cleargreen™ does not require the addition of an external
seed biomass to function.
FLEXIBILITY OF USE:
• Process adapts depending on the quality of effluent to
be treated
• Automation of process controls
• Robust adaptability to variations in flow, load and
effluent composition
• Process that is very beneficial for plant rehabilitations
A specific treatment after anaerobic sludge digestion: with
Cleargreen™, the loads of ammonia and nitrates do not return to
the head of the water treatment line, but are treated in an effective
manner.
The reactor is equipped with sophisticated controls, continually
monitoring the system to limit human intervention.
SUSTAINABLE DEVELOPMENT :
• No reactive agents such as external carbon needed
• Contributes to the preservation of energy resources
• Automatic regulation of air supply = control of consumption

Cleargreen™ is designed to work within a biological sequencing
batch reactor (SBR) such as Cyclor™, a Degrémont reactor that allows
the successive completion of all treatment phases in the same tank.
