Shenzhou Decanter Centrifuge for Wastewater Treatment

Sludge dewatering Decanter Centrifuge

The main purpose of wastewater sludge treatment is to remove as much suspended matter as possible and achieve solid-liquid separation before the discharge of wastewater and sludge. This purifies the wastewater and concentrates the sludge, thus realizing the recycling of water resources.

Shenzhou wastewater treatment centrifuges can be used in urban domestic sewage treatment, chemical sewage purification, sludge thickening and other related sewage and sludge treatment industries. Modern wastewater treatment processes and discharge standards are becoming more and more stringent, and the subsequent treatment of dewatered sludge cake is more difficult, whether it is stacked, dried or incinerated, placing higher demands on the key equipment for residual sludge treatment. Shenzhou SEPARATION can provide professional technical support and customized services for your specific needs.

 

All sewage sludge is different: "Sewage sludge is always unique - all sludge has its own characteristics, which means the overall conditions are never the same.The Shenzhou centrifuge can be customized for the quality and special characteristics of the sewage sludge treated on site.

Wastewater Treatment Process

Cut and crush the biochemical sludge.
Pump the sludge (concentration ≥0.5~4%) into the centrifuge.
Add (concentration 1~3‰) PAM solution into the feed pipe through the automatic dosing device to make the sludge form flocs into the centrifuge.
The dewatered sludge cake is discharged from the bowl.
The dewatering system is widely used in oxidation ditch, AB, A/O, A3/0, SBR, MBR, anaerobic fermentation and other processes as well as traditional wastewater treatment processes, and can treat urban domestic sewage, municipal sewage, garbage leachate, municipal tap water and some industrial wastewater.

How the Decanter Process Works:
* 1: The slurry is brought into the centrifuge through an intake pipe and onto a conveyor.
* 2: Utilizing an internal feed compartment, the conveyor moves the slurry through a nozzle into the bowl.
* 3: The bowl rotates at high speeds to induce centrifugal forces.
* 4: High speed rotation separates the solid material from the liquid in a matter of seconds.
* 5: The conveyor delivers the solid material upwards where it is discharged through a nozzle.
* 6: The solid material removed, the purified liquid is released from a separate output. The ability to purify a liquid makes
decanter centrifuges ideal for waste water treatment facilities. However, there are variety of industries for which such
centrifuges play an important role. Similar to other decanter equipment, centrifuges are simple to install and do not require a foundation to build upon. Their efficiency saves time and materials and is an essential component for many blue collar industries.

What is a Decanter Centrifuge?

Horizontal Bowl centrifuges are also known as decanter centrifuges, centrifugal decanters or simply decanter machines and are primarily used for separation of liquids from appreciable amounts of solids. Decanters can separate over
50% (v/v) solids from liquids on a continuous basis. Typical industrial decanter applications include Crude Oil Tank Bottoms; Waste Oil; Industrial Wastewater; Sludge Dewatering; Fish Meal; WVO/UVO De-Sludging; Paint Sludge; Rendering etc. etc.

How does it work? 

A decanter centrifuge separates solids from one or two liquid phases in one single continuous process. This is
done using centrifugal forces that can be well beyond 3000 times greater than gravity. When subject to such forces, the denser solid particles are pressed outwards against the rotating bowl wall, while the less dense liquid phase forms a concentric inner layer. Different dam plates are used to vary the depth of the liquid - the so-called pond - as required.

The sediment formed by the solid particles is continuously removed by the screw conveyor, which rotates at a different speed than the bowl. As a result, the solids are gradually "ploughed" out of the pond and up the conical "beach". The centrifugal force compacts the solids and expels the surplus liquid. The dried solids then discharge from the bowl. The clarified liquid phase or phases overflow the dam plates situated at the opposite end of the bowl.

Horizontal Decanter Centrifuges Centrifuge World offers a wide variety of horizontal continuous cleaning decanter centrifuges which provide effective, low-maintenance solutions to continuous liquid clarifying and / or solids dewatering with advanced process and mechanical performance features.

Decanter centrifuges are extremely versatile and capable of adapting to varying throughput and process and material types. The machines are easy to adjust, require little operator attention, are relatively quiet and feature a small footprint.
Biodiesel Centrifuges: Centrifuge World offers a wide range of manual clean and self-cleaning biodiesel centrifuges process capacities ranging from 1 to 30-gpm.

Decanter Centrifuges Limitations:
* The decanter centrifuges cannot separate biological solids with very small density differences, such as cells and viruses. A competitive process that is capable of separating these difficult-to-separate solids is the tubular-bowl centrifuge.
* The machine can be very noisy and can cause vibration.
* The device has a high-energy consumption due to high G-forces.
* The decanter centrifuge has high equipment capital costs. Hard surfacing and abrasion protection materials are required for the scroll to reduce wear and therefore reduce the maintenance of the scroll wear.
