Status |
The assignment started in August 97 and
was successfully completed in December 98. The plant
is now in full treatment capacity. As this is not a
biological process, the plant is simply shut down during
times of no production of dyeing cloths. Moreover, the
plant design permits batch operation to suit the highly
varying effluent flowrates by operating it in the required
number of batches accordingly. |

Some of the key parameters of the raw
effluent and the treated water quality obtained are
