The polluted water samples were collected from Singanallur Lake from Coimbatore city for the study purpose. The domestic waste waterwas collected from a hotel near the PSGR Krishnammal College campus, Coimbatore.For each experimental run, 1 kg of activated carbon and 250 gm of sand was mixed well in a tray. Then it was filled in gunny bags which were later stitched on the four sides. The domestic waste water and polluted water is taken in two clean buckets respectively. The gunny bags with activated carbon are then introduced into both the buckets. The water quality parameters were checked for physicochemicalparameters as per standard methods before and after the treatment and the efficiency dose of activated carbon was determined.
