To tackle the highly deteriorated raw water quality of River Godavari, the existing raw
water treatment plant at Maharashtra State Electricity Board's Nasik Thermal Power
Station was augmented by retrofitting one of its three streams. Apart from additional
flow requirement over the years, the primary purpose was to increase the removal
efficiency of organic matter in raw water. The vertical flow sludge blanket tanks were
retrofitted with rapid mix-slow mix and tube settling system. This required a change in
flow pattern from predominantly vertical to horizontal. The location of mixers in the
hopper bottom tank with a non-regular geometry complicated the issue. All modifications
were completed in thirty days. Initial results are encouraging. Turbidity reduction has
been satisfactory, along with substantial reduction in organics. However, it will be some
time before the system potential is completely established for reduction in organics and
confirmation of the advantages thereof. Includes 18 references, figures.
