Rheological properties of concentrated distillery spent wash and some metal corrosion studies
185-193Spent wash
generated by the alcohol
distilleries is a major
source of ground
water pollution. Various treatment strategies,
which include
aerobic, anaerobic
digestion, thermal treatment and incineration
have been adopted with reasonable
success. For
the rigorous engineering
analysis of any of these
processes, the information
regarding the physico-chemical properties
of
this eflluent such
as density, surface
tension and viscosity
are essential. The
rheological properties
of concentrated distillery wastes
at room temperature and
elevated temperatures
were measured. The rheological
properties have been
correlated to
solid concentration of the waste
in the dissolved and suspended
state at
room temperature.
For highly
concentrated wastes
(viz. 50 % and
60 % by weight of solid
concentration)
the variation
in rheological properties with temperature
were also studied. A
rheological model has been used to
explain the observed
results. The Bingham
model was found suitable
to explain the rheological
properties of the concentrated
distillery wastes at
ambient temperature and elevated
temperatures. The corrosion rates of different materials during
evaporation of distillery <span style="font-size:12.0pt;
