Management
of Distillery Wastewater
|
|
Foreword
The tecnnologles
currently used by distilleries tor treatment ot wastewater are biomethanation
followed by two-stage biological treatment and disposal in water courses
or for utilization on land for irrigation, composting with or without
biomethanation and concentration and incineration.
These technologies treat the wastewater upto a certain level. However,
there are limitations posed by these technologies for full compliance
of prescribed standards. These limitations are either due to :ligh
cost of treatment or inherent inability of technology to remove certain
pollutants like total dissolved solids and colour to safe and acceptable
limits for disposal into surface water or on land.

| This
report is the outcome of deliberations of a Nationa( Committee of
experts, which was constituted by CPCB to evaluate the performance
of available technologies and work out a strategy for management of
distillery effluents. Shri P.M. Ansari, Addl. Director; Dr. K.C. Rathore,
Senior Environmental Engineer and Zonal Officers of CPCB assisted
in preparing this report. We hope, it will be useful to the distilleries,
consultants as well as all those who are interested in developing
cost effective technologies for treatment and safe disposal of distillery
effluents. |
