High Capacity Decanter Centrifuge Machine
,Stainless Steel Fish Oil Decanter Centrifuge
,60Hz Stainless horizontal decanter centrifuge
The Industrial Decanter Centrifuge for Chemical Plant Waste Slurry is designed for continuous solid-liquid separation of complex chemical process residues, wastewater sludge, and industrial waste slurry.
Chemical plants often generate waste streams containing fine particles, inorganic salts, catalysts, polymers, pigments, and other suspended solids. The decanter centrifuge uses high centrifugal force and continuous scroll conveying to separate clarified liquid from concentrated solids.
By reducing slurry volume, recovering valuable materials, and improving downstream treatment efficiency, the decanter centrifuge helps chemical plants optimize waste handling, reduce disposal costs, and improve resource recovery.

Complex Slurry Composition
Chemical waste slurry may contain mixed solids, dissolved substances, fine particles, and unstable components.
Fine Suspended Solids
Small particles may settle slowly and are difficult to separate with conventional equipment.
Corrosive Components
Chemical slurry may contain acids, alkalis, chlorides, solvents, or other corrosive substances.
Variable Feed Conditions
Waste slurry characteristics can change with different production batches.
Waste Reduction Requirements
Chemical plants need to reduce sludge volume and improve disposal efficiency.

How the Decanter Centrifuge Works
1. Chemical Slurry Feeding
Chemical waste slurry enters the rotating bowl through a controlled feeding system.
2. Solid Sedimentation
Under centrifugal force, 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 flows toward the liquid discharge area.
4. Solids Conveying
The scroll continuously transports settled solids toward the conical discharge end.
5. Separate Discharge
Clarified liquid and concentrated chemical solids are discharged continuously through separate outlets.
