drilling mud decanter centrifuge
,solid liquid centrifuge
The Industrial Decanter Centrifuge for Zirconium Processing is designed for solid-liquid separation in zirconium production and mineral processing applications, including zircon sand treatment, zirconium chemical slurry separation, and process residue dewatering.
It provides continuous separation of fine zirconium-containing solids, mineral particles, and process slurry, helping improve material recovery, reduce liquid content in solids, and maintain stable downstream processing.

How the Decanter Centrifuge Works
1. Petrochemical Sludge Feeding
Petrochemical sludge containing oil, water, and suspended solids enters the rotating bowl through a controlled feeding system.
2. Solid Sedimentation
Under centrifugal force, dense solid particles move toward the bowl wall and form a concentrated solids layer.
3. Liquid Clarification
Separated liquid remains in the inner liquid zone and moves toward the clarified liquid area.
4. Solids Conveying
The scroll continuously transports concentrated sludge solids toward the conical discharge end.
5. Continuous Separation
Dewatered sludge solids and separated liquid are continuously discharged for further treatment or recovery.

Why use a decanter centrifuge for petrochemical sludge treatment?
A decanter centrifuge provides continuous dewatering and solid-liquid separation, helping reduce sludge volume and improve downstream treatment efficiency.
Can the centrifuge handle oil-containing sludge?
Yes. The decanter centrifuge is suitable for many oil-containing sludge applications, including refinery sludge and petrochemical wastewater sludge.
Is a closed design required for petrochemical applications?
A closed system is recommended because it helps reduce odor, hydrocarbon exposure, and environmental contamination during operation.
Can the differential speed be adjusted for different sludge conditions?
Yes. Adjustable differential speed allows operators to optimize solids dryness, liquid clarity, and processing capacity.
What materials are available for petrochemical sludge applications?
Material selection depends on chemical composition and corrosion conditions. Stainless steel and customized corrosion-resistant materials are available.
Peony provides decanter centrifuge solutions for petrochemical sludge treatment, supporting refineries, chemical plants, EPC contractors, and wastewater treatment projects.
