Structure and Major Components of the MS-Diaphragm Decanter
The main body of the SBR Decanter features a combined structure of upper/bottom
plates, and a diaphragm-type partition wall which discharges supernatant using
pressurized air. On the side of the main body is a scum prevention plate designed
to prevent scum from being discharged with the supernatant. The system incorporates
a guide rod composed of multiple pipes, and a javara hose which enables the
main body to ascend and descend freely.
Structure of the Diaphragm Decanter
Operation of the MS Diaphragm Decanter
The operational sequence of this device is as follows;
- Feed valve ON, discharge valve OFF (shut-off wastewater discharge).
- Wastewater input into reactor.
- Stop inflow of wastewater at the appropriate level.
- Carry out biological and physical reaction.
- Sludge deposition complete.
- Feed valve OFF, discharge valve ON.
- Discharge supernatant.
- Discharge from reactor now complete.
As described above, wastewater is treated biologically and physically, and
is then discharged.

|
Outline
|
A round, floating type discharge unit that moves up/down
along a guide rod. The discharge rate of the supernatant is controlled
by a solenoid valve which regulates the air pressure in the diaphragm
valve between the inflow/outflow weir. The supernatant is discharged through
the space between the guide pipes.
|
A power-driven arm type decanter. The discharge trough
is lifted above the reactor when not in the discharging phase. For discharging,
the decanter is lowered to a limited depth at a preset speed. The length
of the decanter has to be set in accordance with the width of the reactor.

Up/Down Travel
|
Up/down travel to more than 40% of the reactor's depth.
|
Limited by the length of the electrical/mechanical actuator.
|
|
Power
|
1.0 KW Set/day
|
7.5KW Set/day
|
|
Scum Loss
|
No scum loss occasioned because the decanter floats
on the surface and is equipped with a scum protecting plate.
|
Equipped with a scum protecting plate, but scum loss
cannot be prevented when the decanter touches the surface.
|
|
Width and Length of Reactor
|
Not limited
|
Must fit the decanter's length.
|
Outflow of Sludge Deposit
Since the supernatant is discharged calmly at a sufficient time after precipitation
following the aeration of the SBR process, sludge is not agitated, resulting
in superior discharged water quality (SS10mg/L)
Width and Length of Reactor
The MS-Tech Decanter is not limited by the width or length of the reactor.
