To understand
the system
operation, let us take an example of
Sewage treatment system.
BUFFER TANK. Wastewater is collected in a buffer tank. This tank acts as balancing reservoir and is used to separate solids, paper and other waste to be received with the waste water. Enter here for more information on buffer tank..
EEC BIO SYSTEM. The first and the second chamber of the EEC High-Speed Bio Tec is filled
with AMB Bio Media and water. The last chamber, which is a parallel plate
settler is filled with water only. Before starting pumping of waste water, the system
blowers starts. The blowers force air through the
manifolds into the first 2 chambers of the bio system. The influent
wastewater enters the first chamber and comes in constant contact with
the AMB Bio Media and air. Large surface area provided by the AMB Bio Media helps
the bacteria to form large colonies on the AMB Bio Media. Circular motion of
the media is caused by the air flow. Each element of the media slowly moves
in a circular motion from the surface to the bottom and then upwards again.
During this movement, it is in constant contact with the injected air. Slowly a bio film develops over each element, which disintegrate the bio
mass present in the effluent.
From the first chamber the effluent flows to the second chamber through the
perforated partition at the top. The same treatment is repeated in this
chamber and the remaining bio mass from the first chamber gets fully
digested.. The treated water then enters the third chamber at the top
A baffle plate guides the water entering the third chamber downwards. Then
it enters the parallel plate settler from the bottom. The settler provides a
large surface area for the suspended particles to settle down on its surface
and the same are guided towards the bottom. Clean water is let out of the
system from the outlet provided at the top of the third chamber.
When the level of the influent drops in the collection tank the feed pump
gets tripped. Simultaneously the sludge pump is started. The sludge pump
draws sludge from the bottom of the 3 chambers and discharges it into a
sludge separation process. This process separates out heavier sediments from the sludge
which settle in the collection tube mounted at the bottom of the
sludge separation system built into the EEC High-Speed Bio Tec. Clarified water is discharged back in to the first chamber of
the bio reactor. The sludge pump operates for a pre-set time and is stopped
automatically. The solid sludge accumulated in the sludge collection tube is
discharge out periodically. This sludge can be used as a manure or for land
farming. Effluent water from system can be used for irrigation. Back to STP information or Industrial Bio Systems
