Being a system discharging upper clear after sedimentation of solid matters mixed in reactor (SBR), this system decanter in diaphragm method which is adopted to prevent sedimentary floating solid matters from emerging again and being discharged with upper clear water and prevent scum generated during treatment from being discharged with upper clear water, and it also can discharge all upper clear water by natural pressure. Especially to maximize accuracy and speed of system, such a technology is used that maximizes efficiency of reactor thanks to diaphragm, by making it respond within shortest span of time and discharging only well-treated upper clear water.

 

Classification Upper clear water discharging system, using diaphragm
Floating fluid Water pressure method
Discharging method Opening/closing diaphragm valve
Composition of main body STS304, PE, BOLT, DIAPHRAGM
Scope of application Dirty water, sewage and wastewater disposal plant

 

Upper and bottom plate of main body of decanter is coupled and there 
is separating system in diaphragm type in the middle of decanter. 
Upper clear water is discharged by using air pressure through diaphragm 
and scum preventive plate is installed at side of main body 
to prevent scum from being discharged together with treated water. 
This system is composed of guide rod which consists of several pipes 
for main body to move up and down and jabara hose for main body to 
ascend and descent freely.

 

Degree of loss of sedimentary sludge

Quality of discharged water is excellent without stirring sedimentary 
sludge at all because water is discharged in perfect stationary 
state without underwater waves, after enough time has passed for 
sedimentation after aeration as SBR process. (SS 10mg/L)

 

 

Aeration in reactor

ECOCO decanter can be installed and operated without limitation.

 

 

Comparison with imported product on function

Classification of function Applied product (our product)
(Diaphragm Decanter)
Similar competitive product of Advanced country
(Name of product : ABJICEAS Decanter)
Summary of decanter This is cylindrical type discharging system
which moves up and down along with guide
rod in floating state on water surface, and it
discharges upper clear water through space
between guide rods, adjusting amount of
discharge of upper clear water by controlling
air pressure within diaphragm valve installed
between internal inflowing/outflowing weir by
means of opening/closing solenoid valve.
Being arm type decanter which is operated by power
unit, discharging gutter is lifted outside of reactor
except for discharging process, and it descends to limit
depth by power unit at pre-determined speed at the
time of discharges upper clear water. However,
length of decanter should be adjusted to width of reactor.
Range of up and down
Movement of
Up and down movement,
more than 40% of depth of
It is limited depending on length of electric,
mechanical actuator.
Power to be required about 1.0 kW.Set/day about 7.5 kW.Set/day
Degree of loss of scum There is no loss of scum because system is
always floating on water surface and scum
preventive plate is equipped.
Even though there is scum preventive plate, it cannot
prevent scum loss when it touches water surface every
time discharge is processed.
Width of reactor No limitation to be adjusted to the length of decanter
