Titanium industrial decanter centrifuge
,Chlor Alkali decanter centrifuge
,Chlor Alkali decanter separator
The Industrial Decanter Centrifuge for Chlor Alkali Plant is designed for solid-liquid separation in chlor alkali production processes, including brine purification, salt slurry treatment, and chemical residue dewatering.
It provides continuous separation of suspended solids, insoluble impurities, and chemical residues, helping improve brine quality, reduce downstream fouling, and maintain stable chlor alkali operation.
- Brine purification residue dewatering
- Salt sludge separation in chlor alkali plants
- Insoluble impurity removal from saturated brine
- Calcium carbonate and magnesium hydroxide sludge treatment
- Chemical precipitation slurry separation
- Waste salt recovery
- Chlor alkali wastewater treatment
- Solid residue concentration before disposal or reuse
High Salt Content
Brine systems contain high concentrations of dissolved salts and suspended impurities that require reliable separation.
Chemical Corrosion Risk
Chloride-rich materials can cause corrosion on equipment surfaces and require suitable material selection.
Fine Solid Particles
Precipitated impurities such as CaCO₃ and Mg(OH)₂ may contain fine particles that are difficult to separate.
Continuous Production Demand
Chlor alkali plants require stable 24/7 operation with continuous solid discharge.
Strict Product Quality Requirements
Brine purification directly affects membrane cell performance and overall production efficiency.

How the Decanter Centrifuge Works
1. Brine Slurry Feeding
Brine slurry containing suspended solids enters the rotating bowl through a controlled feeding system.
2. Solid Sedimentation
Under centrifugal force, dense impurities move toward the bowl wall and form a concentrated solids layer.
3. Liquid Clarification
Separated brine remains in the inner liquid zone and moves toward the liquid discharge area.
4. Solids Conveying
The scroll continuously transports settled solids toward the conical discharge end.
5. Separate Discharge
Clarified brine and concentrated solids are discharged continuously through separate outlets.
