Effluent Treatment Plant Process
a) Pre-treatment
Effluent Treatment Plant process Odisha India includes a classic pre-treatment unit with a preliminary coarse screening followed by fine sieving for the whole of the throughput. The separation process continues with the effluent being directed to the dry weather biological channel up to a flow of 8.2 cubic meters/sec. The excess flow is directed to the wet weather channel to a maximum of 16.4 cubic meters/sec.

b) Biological treatment
The dry weather flow is sent to grit and oil removal before being processed in 12 biological treatment channels. Each of these channels has first a biological degrading zone for phosphorus, followed by one for carbon and nitrogen (AZENIT-P® process( cfr section 6)). The effluent is then sent to basins where the treated water is clarified through decantation of the biological mud. Part of the decanted sludge is sent back to the start of the treatment process to be fed into the biomass. The clarified water is sent out to be returned to the Senne. Waste Water Treatment Plant process in India is very quick now-a-days.
c) Wet weather treatment
Wet weather is characterized by a re-suspension of the solid material that had sedimented in the network through dry weather. The treatment of this sewage requires specific techniques.

The wet weather flow is first sent through a rough grit removal to eliminate particles bigger than 300 micrometers (MECTAN® process). Then it is settled using the ACTIFLO® process (cfr section 6). This rapid settling technique involves lumping the effluent together using a coagulant and then mixing it with sand. With its high density, the sand speeds up the separation out of the agglomerate in the decantation stage. Effluent Treatment Plant Process Odisha India

d) Sludge Treatment
a) Process

The principle is to break down the organic material in the sludge so as to obtain an entirely mineral final residue. This break-down process uses two complementary procedures: digestion in the anaerobic phase and wet oxidation.
