Alfa Laval’s efficient solutions for
reducing the volume of wastewater help to decrease disposal
costs significantly. We deal with all kinds of sludge, from
simple natural sedimentation, secondary biological treatment or
advanced chemical treatment.
Municipal waste. We are involved
in the processing of sludge from the public sector from at
least 200 million people.
Industrial waste. Our solutions
are used in more than 1,000 industrial applications.
Water at water works. Our
systems help produce nearly 400 million gallons of potable
water every day.
ALDRUM – Thicker sludge is better
The ALDRUM drum
thickener is a range of mechanical sludge thickeners and works
on the principle of conveying polyelectrolyte treated sludge
through a slowly rotating drum filter. The sludge remains in the
drum, while the water phase passes through the filter cloth.
Sludge concentration can be regulated by adjusting the feed
rate, angle and speed of the drum.
Preheating, heating and cooling of industrial and municipal
The Alfa Laval
Spiral Heat Exchanger is intended for sludge applications in
which heat is interchanged between sludge flows. It consists of
a spiral – wound from sheets of metal strips – that form two
concentric spiral flow passages. The channels are alternately
welded on opposite ends to form a hot and cold channel. The hot
channel is then closed while the sludge channel is accessible
– More sludge treated, more efficiently
complete range of G2 decanter centrifuges feature a compact,
modular design with all critical parts made of wear-resistant
materials. The result is reliable, continuous operation and
easy, trouble-free process control. Compared to previous
generations of equipment, the G2 decanters provide 2 – 3% drier
sludge cake or as much as 30% greater capacity.
mounted units – Plug-and-play dewatering modules
Based on the
ALDEC decanter centrifuges, the ALSYS is a dewatering module
used for reducing sludge volumes. Its plug-and-play design
allows for rapid, easy installation on-site and the unit’s
compact layout reduces space requirements and ensures easy
cost savings from automatic optimization of dewatering:
