LOW
TEMPERATURE
DRYER
Dry sludge with reduced energy
consumption and lowered CO2
emissions
PRODUCT
Treat and recover
sludge at a low
energy cost
THE LOW TEMPERATURE DRYER BY AQUALOGY STC DRIES
SLUDGE WITH THE RESIDUAL ENERGY RECOVERED FROM
PROCESSES OPERATING ON SITE
THE BENEFITS FOR YOU
RECOVERY of sludge coming from wastewater treatment plants
SAVINGS thanks to the low consumption of primary energy provided
by the low temperature dryer and the use of the site’s residual energy.
REDUCTION of the environmental impact thanks to low odour, dust
and CO2 emissions.
• The dryer can be adapted to the energy needs of every client and
every country: in order to make the most relevant economic and
environmentally-friendly choices, the dryer can operate entirely on
electricity or be combined with residual energy
•
The dryer, marketed by the company Aqualogy STC, an AGBAR
subsidiary, works with urban and industrial sludge and several
drinking water processes
70%
• Thanks to low temperature evaporation, the sludge loses up to 70% of
its volume reaching up to 90% dry content
Reduction
of sludge
volume
• The dryer does not risk exploding (no ATEX risk)
THE LOW TEMPERATURE DRYER
BY AQUALOGY STC
The low temperature dryer allows municipalities to reduce the volume of
sludge coming from wastewater treatment plants and allows companies
to recover residual energy. The dried sludge can then easily be recovered,
be reused in agriculture or serve as fuel in the coal industry, cement
works, etc.

1
 Moist sludge comes from a silo located at the head of the dryer. With
3
the help of an extractor, it is placed in the form of strands on the upper
belt of a conveyer belt, thus allowing easier heat exchange to take place.
2
 The belt moves the sludge forward into a closed tunnel where air,
heated to 65/80°C, circulates. No handling is required for this process. The
pre-dried sludge then drops onto a lower belt, where drying is completed.
 After drying, the finished product obtained is easily transportable, having
lost up to 70% of its volume reaching up to a 90% dry content rate.
