V
ery high gravity technology (VHG) was implemented
on industrial scale fermenters to study the reduction in
fresh water consumption in the process as well as ethanol
and by products formation during molasses fermentation.
Different brixº 32, 36 and 40 with aeration rates 0.00, 0.20,
0.40, and 0.60 vvm has been applied. The maximum ethanol
production was 12.2% (v/v) at 40º brix with 0.2 vvm aeration.
Byproducts have the increasing trend with the brixº but
aeration rate 0.2 vvmwas found to be optimum for byproduct
formation throughout the study. The high ethanol % attained
had eased the distillation process and steam consumption
reduced significantly. More over water consumption was
reduced by 35% decreasing the stillage volume. Reduction
in steam consumption decreases the overall water utilization
by improving the economics of industrial ethanol production
process significantly. Decrease in stillage volume is helpful in
combating this environmental pollutant efficiently.
