The treated effluent conforming to stipulated standards shall be invariably used for irrigation purpose and shall not be discharged to any stream, river or surface water body. Sugar factory shall possess adequate land to ensure complete utilization of treated effluents for agriculture.
The application of treated effluent shall be controlled so as to avoid either flooding of land or ground water contamination. Before allowing the use of treated effluent for irrigation, the State Pollution Control Board shall ensure that the factory submits a report on geophysical characteristics and assimilation capacity of land. Adequate number of observation bores/test wells shall be provided by the factory in and around the irrigated area to monitor ground water quality.
|The Standards for Effluents and Emissions Discharged from Sugar Industry|
|Concentration not to exceed Milligram per litre.|
|Bio-chemical Oxygen Demand (5 days at 20.C)||100 for disposal on land.|
|Suspended Solids||100 for disposal on land.|
|Bagasse-fired Boilers.||Emissions.||Concentration in mg/NM3|
|(a) Step grate.||Particulate Matter||250|
|(b) Horse Shoe/Pulsating Grate.||Particulate Matter||500 (12% CO2 )|
|(c) Spreader Stroker.||Particulate Matter||800 (12% CO2)|
NOTE: In the case of horse shoe and spreader stroker boilers, if more than one boiler is attached to a single stack, the standard shall be fixed based on added capacity of all the boilers connected with the stack.
