A. Scope of the workThe scope comprises supply, installation, testing & commissioning of effluent treatment

plant of total capacity 30KL/day at RIICO, Chopanki for M/s Kamdhenu Paints. The proposed E.T.P. shall be suitable for load ranging from +_25% of specified load to adjust the varying pattern of flow. The effluent as per parameters given in para B shall be treated to produce effluent of quality to reach at least a standard mentioned in same para of the specification. The supplier shall handover the plan tin full operational condition to the satisfaction of the Plant Engineer.

Effluent Treatment Plant

The different streams of effluent coming to the effluent treatment plant comprising of the waste water from different areas are taken to the oil and grease chamber after passing through M.S. shutter gate & bar screens. In the oil & grease chamber excess grease and oil are separated .From here the effluent free of any floating debris, oil ,grease is taken into equalisation tank for homogenisation. The equalised effluent is pumped into flash mixer and further to a flocculation chamber. In flash mixer alum and lime are dosed for coagulation and pH boasting respectively.

In the primary clarifier the flocks formed in the flocculator are removed and the clear supernatant flows by gravity to an aeration chamber (1stage). The sludge is taken into the sludge drying beds.The stream is further taken into an aeration chamber for second stage biological oxidation. The oxygen required for both stages is provided with the help of blowers through diffused aeration. The effluent from the aeration chamber is taken to a gravity type secondary clarifier. The biological sludge is separated in the secondary clarifier & recirculated into the aeration chamber. Excess sludge is taken to the sludge separation i.e. sludge drying beds for final decanting. The clarified treated effluent is taken into the collected pit. The treated effluent is then passed through pressure sand filter before collection of treated effluent in treated water tank from where it is discharged into the external drains.Schematic process diagram is enclosed for reference.The effluent treatment plant shall essentially include but not limited to following units:a) Preliminary treatment unit such as mechanical bar screens, screen chamber or any other

equivalent mechanism.b) Secondary treatment unit including aeration for removal of B.O.D. & S.S.c) Neutralisation &settling tanksd) Necessary Blower, stirrers, pumps &motorse) Sludge drying beds
