| 1. Effluent Tank |
|
Raw solution differs depending on the influent volume and its properties, so an
influent tank with a level gauge is provided to pool the influent for 2 or 3 hours
or longer. |
| 2. Regulation Tank, Neutralization Tank, Flocculation Tank |
|
The influent which has collected in the influent pit is pumped by the influent pump
viathe flow regulator to the regulation tank → neutralization tank → flocculation
tank. PH electrodes are provided. |
| 3. Flocculant Tank, Conditioning Tank, Flocculant Aid Tank |
|
Slaked lime is pumped to the regulation tank, the sulfuric acid band is sent to the
neutralization tank through PH control and macromolecular material is sent to the
flocculation tank in the neutral and flocculate operation. |
| 4. FRG Tank |
|
As suspended solids in the raw solution pass through the FRG tank following
regulation, neutralization and flocculation, they form complete flock. |
| 5. Sedimentation Tank |
|
Suspended solids which have passed through the FRG tank enter the sedimentation
tank which has built-in inclined plates, where sedimentation and separation occur.
Electric ball valves (Model DSP-2 is equipment with manual valves) in the bottom of
the sedimentation tank are provided which automatically open to discharge the
sedimentation sludge into the sludge pit. |
| 6. Sludge Pit |
|
Sludge discharged from the sedimentation tank accumulates in the sludge pit. |
| 7. Dehydration |
|
Sludge is moved by a pump from the sludge pit through a pracoat vacuum rotary filter
(Hypervac) or filter press to a dehydrator for treatment. |
