| 1. |
Drive
unit Two separate drive units are provided for flocculator & clarifier mechanism so that both are operative independently. |
Flocculator
drive Flocculator drive comprise of motor connected by worm reduction gear box by flexible coupling, chain & sprocket to get required RPM of flocculator paddles of suitable size which are suspended from the arms of flocculation zone. Clarifier drive Clarifier drive also comprises of motor connected to worm reduction gear box by chain & sprockets to impart slow motion to the scrapper. Clarifier mechanism is used continuous to remove the settled sludge from the centre of the tank. The drive unit & feed well (MS) is fixed at the centre of bridge which is designed to take static & dynamic load of the drive unit. |

| 2. |
Superstructure
comprising of steel structural bridge spanning half/full diameter
of the tank as per data sheet. Necessary chequered plate & handrails
are provided on the bridge so that it can be used as walkway
to have access to the drive unit at the centre. |
| 3. |
The
drive unit rotates structural steel cage to which rake arm is attached
which rake the bottom of the tank twice per revolution. Rake arm
is provided with adjustable neoprene/brass squeezes for efficient
scrapping. |
| 4. |
The
drive unit, feed well & rake arms are supported by structural
bridge which in turn is supported as shown in the g.a. drawing. |
| 5. |
The
bottom of the structural steel cage rests on guide bearing fixed
to the tank cone. Suitable cone scrapper is included in our supply. |
| 6. |
The
feed is let into the clariflocculator feed well. The clarified
water is collected through peripheral launder & settled sludge
through the centre of the tank. |
| 7. | Necessary
weir plates to be fixed to the outlet launder can also be provided
on request. |
| 8. | Also
floating scum scrapper with scum box if required can be included
