gave maximum COD reduction
of about 70% from its initial value of 3520 mg/L (Table 6.20). The COD reduction is accom-
panied with the formation of settleable solid residues, which is enriched in carbon.
The kinetic analysis of thermolysis revealed that the process is comprised of two succes-
sive steps—an initial fast step followed by a slower second step for COD reduction. The
two steps can be represented by a simple global power-law rate expression giving rst
order with respe ...
