Heat exchanger
October 1st 2009 The latest version of Alfa Laval's
Spiral Heat Exchanger for
sludge/water duties, the
ALSHE STW, has been
developed specifically
for cooling industrial
waste and for a number
of duties involved in
the treatment of
domestic sewage sludge
including: heating
sewage sludge in the digester; heating
during pasteurisation; preheating
sludge to enhance dewatering; and
cooling industrial sludges and other
waste streams.
Used for heating, cooling and heat
recovery duties, the ALSHE STW has
one 25mm wide freeflow
channel, enabling
it to handle sludges
with minimal risk of
fouling. This
capability is enhanced
by the high shear,
which enables selfcleaning. More articles from Alfa Laval Limited: |
