Product Description

Product Description

Decanter centrifuge for Urban Waste Water Treatment Industry

Waste waters are produced by medium and large scale settlements such as provinces, districts, towns and villages. Such municipal (domestic) waste waters are to be treated. Processes in municipal waste water treatment plants vary depending on their area of use since they contain domestic and partially industrial waste waters and rain waters.
 

While the plants vary depending on the project in general they are designed to include stages such as coarse grid, fine grid, sand arrestor, oil catcher, lifting station, nitrogen phosphor elimination tank (biophosphor), aeration tanks, settlement tanks, distribution structures, sludge concentration units, digesters, sludge dewatering units, disinfection unit and odor elimination units.

 

Shenzhou turbo blowers are employed in sand arrestor, aeration tank, sludge tanks and stabilization tanks of treatment plants. Nearly 50-60% of the overall power consumption of a treatment plant is used by blowers. Therefore, blowers are among the most significant and technological equipment pieces in a waste water treatment plant and they impact the plant operating costs significantly.

Shenzhou decanters and screw presses are employed in sludge concentration and/or dewatering stage which is generally the final stage of waste water treatment plants and used for solid and liquid separation. Elimination of sludge has critical importance for ensuring continuity of the plant. Sludge elimination constitutes nearly 25-30% of waste water treatment plant investment and 45-60% of the operating costs. Selection of adequate dewatering equipment and process optimization are very important for minimization of costs.
 

Urban Waste Water Treatment Process
SHENZHOU Centrifuge Technologies employs decanters and screw presses for primary sludge (PS), activates sludge (WAS), extended aeration advanced activated sludge, aerobic / anaerobic digested sludge, MBR sludge produced in municipal waste water treatment plants.

Concentration Process: It is used for increasing the solid matter content of the sludge which is approximately 1-3% to the levels of 6-8%. Concentrated sludge is then fed to dewatering decanter or digester.

Dewatering Process: Decanter or screw press is used for dewatering of primary or secondary sludge.

SHENZHOU Centrifuge Technologies turbo blowers are used for supplying air needed in sand arrestor, aeration tank, sludge tanks and stabilization tanks with a polytrophic efficiency up to 84% and an extensive operating range.
 

Process
Primary sludge dewatering
It is generally the sludge output from primary (pre-) sedimentation and has a grey color and slimy structure. It generally has a very strong smell. Digestion and dewatering of such sludges is easier than biological sludges.
Presedimentation tank contains settling / separable coarse particles.
Has an average solid matter content of 2-4% and volatile solid matter content of 80%. Feeding of sludge to the dewatering equipment is performed from sludge conditioning and storage tank.
