| 1. |
Two
separate drive units are provided for flocculator & clarifier
mechanism so that both are operative independently. Flocculator
will rotate from the centre while clarifier will rotate from end. |
Flocculator
drive The flocculator drive comprises of motor connected by worm reduction gear of suitable ratio through flexible coupling, chain & sprocket to get required RPM of suitably sized flocculator paddles which are suspended from the arms of central flocculation zone made of RCC. Clarifier drive Clarifier mechanism is used continuously to remove the settled sludge from the centre of the tank. Clarifier drive comprises of motor connected with worm reduction gear box by chain & sprockets to impart slow motion to the driving steel/tyred wheel moving on periphery of the clariflocculator tank. |
|

Superstructure
comprising of moving steel structural bridge spanning half the
diameter of the tank. The bridge is provided with chequered plate,
MS hand railing & trolley with steel/tyred wheel. |

Sludge
rake arm is suspended from the bridge (moving) which rakes the
tank bottom once in revolution. Sludge rake arm is provided with
adjustable brass/rubber squeezes for proper sludge scrapping. |
| 4. |
The
feed is let into the clariflocculator by means of hollowed central
RCC column at the bottom. The flocculator drive unit, drive cage & rake
arms are supported by central RCC column. |
| 5. |
Necessary
weir plates to be fixed to the outlet launder can also be provided
on request. |
| 6. |
Floating
scum scrapper with scum box & high torque switch can also
