Shenzhou Decanter Centrifuge for Wastewater Treatment
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.
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.
