| Tube Settler:- |
 |
|
| |
 |
| |
| Introduction:- |
|
|
| |
| TUBE SETTLER is the most effective and alternative to the conventional sedimentation process. And, unlike the sedimentation process that demands a great deal of today's valuable space, the compact TUBE SETTLER is not marely a great space saver but helps cut down civil engineering costs substantially. |
| |
| Basic Structure :- |
|
|
| |
Multiple tubular Channels-inclined at an angle and adjacent to each other-separate the suspended solids from water or any other liquid effluent.
Individual tubes are continuous and smooth to minimise mixing of currents within the tube. The configuration and shape of each tube is design to obtain a low Reynolds number and laminar flow conditions for rapid accumulation and settlement of solids through the tubes. The high surface area of tubes enabling substantial improvement of settling capacity |

Working Principle:- |
|
|
| |
| This is a COMBINED UNIT consisting of FLASH MIXER/FLOCCULATOR and SETTLING TANK. |
| |
| FLASH MIXER TANK:- |
| |
| The tank will be fitted with a mechanism consisting of :- |
| |
| TEFC squirrel cage induction IP55 motor |
| |
- Worm gear box.
- Turbine type impeller.
- Shaft.
- Rigid coupling connecting gear box to agitator shaft.
- Base plate with coupling.
- Support channels or beams across the tank shall be supplied and laid by client.
|
| FLOCCULATOR TANK:- |
| |
| The tank will be fitted with a Mechanism consisting of :- |
| |
- Support plate.
- Flocculator drive with motor and gear box.
- Rigid coupling.
- Central shaft.
- Flocculation paddles.
|
| SETTLING TANK (in steel) :- |
| |
The unit shall be made of MS plates and the shell will have suitable supports with inlet, outlet and drain arrangement. It will have steel launder and collection pipes. Settling will be efficiently achieved by tubes which shall be special PVC units with high settling efficiency. The tubes shall be installed and fitted to make continuous settling area and shall be supported on steel supports.
A common walkway with handrails shall be provided to cover Tube Settler and Flocculator/Flash Mixer.
The tank shall be painted with Epoxy Primer and Epoxy Paint from inside and Red oxide Primer and Synthetic Enamel Paint from outside. |

|
Advantages:- |
|
|
| |
- The advantages of tube settlers can be applied to new or existing clarifiers/basins of any size:
- Clarifiers/basins equipped with tube settlers can operate at 2 to 4 times the normal rate of clarifiers/basins without tube settlers.
- It is possible to cut coagulant dosage by up to half while maintaining a lower influent turbidity to the treatment plant filters.
- Less filter backwashing equates to significant operating cost savings for both water and electricity.
- New installations using tube settlers can be designed smaller because of increased flow capability.
- Flow of existing water treatment plants can be increased through the addition of tube settlers.
- Tube settlers increase allowable flow capacity by expanding settling capacity and increasing the solids removal rate in settling tanks.
- Very cost economical since it uses 1/10th of space required by conventional clarifiers.
- No moving parts, operates totally on Gravity.
- No maintenance list.
- Laminar flow ensures excellent treated water quality.
- Wide choice of materials of construction such as steel, concrete/FRP.
- Non-corrosive tubes can be lifted easily for cleaning without shutdown.
- Flexible configurations
- Required Very Less Space
- Easy installation
- No Power Consumption
- Simple in Operation
- Easily Mobility
