Sampling and Analysis
The functioning of the reactor was monitored over a period of 4 months. The
samples at feed, in the reactor and treated effluent were taken on regular basis to
monitor the performance of the reactor. Chemical oxygen demand (COD), total
suspended solids (TSS), total dissolved solids (TDS), MLSS and MLVSS were
regularly analyzed for the untreated and treated effluent as well as sludge according
to the standard methods (APHA 1995 ).
Operating Conditions
The reactor was operated in fill, react and withdrawal mode during initial period of
operation. After stabilization of the process, the reactor was operated in continuous
mode for a period of 3 months.
