Observation:
One treated waste water sample of Sewage Treatment Plant of P.C Chatterjee Memorial Eye Hospital,
Dharmanagar, North Tripura was received from Sri. Subrata Majumder, JEE, NZOL on 04.01.2020 for the
analysis of different physical & chemical parameters. The sample was analyzed in the laboratory of TSPCB using
the standard methods given in APHA, 2012 (American Public Health Association).
From the result table, it has been observed that, all the analyzed parameters of treated waste water sample
of the said unit is within the prescribed standards limit of CPCB (Central Pollution Control Board) for
discharge of effluents.
