Abstract:
High organic strength wastewaters from food industry, distilleries, breweries etc. are
conventionally treated by anaerobic digestion due to low sludge production, derivation of
biogas and low operating costs. However anaerobic process is extremely slow and hence
requires large space and therefore capital cost intensive. On the other hand, aerobic
treatment is rapid, efficient with stable end products yet the considerable sludge formation
is a major disadvantage. Chemical oxidation is extremely rapid, easy to control and able to
oxidize non bio degradable substances but its widespread application is restricted
primarily due to cost consideration. Therefore an integrated approach to high strength
wastewater treatment by taking advantage of the merits of anaerobic, aerobic and chemical
oxidation is an attractive option to develop a sustainable, efficient, intensive and rapid
treatment technology for the treatment of high strength industrial effluents.
