Heats & cools September 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 free-flow channel,
enabling it to handle sludges with
minimal risk of fouling. This
capability is enhanced by the high
shear which enables self-cleaning. More articles from Alfa Laval Limited: |
