Calcium hypochlorite production involves corrosive and strongly oxidizing process streams. During crystallization, washing, or slurry treatment, the material often contains calcium hypochlorite crystals, mother liquor, calcium salt residues, fine particles, and alkaline liquid phase.
A decanter centrifuge can be used for continuous solid-liquid separation in calcium hypochlorite processing. Under centrifugal force, heavier crystalline solids settle on the bowl wall, while the liquid phase forms an inner layer and is discharged through the liquid outlet. The screw conveyor continuously moves the settled solids toward the discharge end.
For calcium hypochlorite projects, equipment selection should not be based only on capacity. More important factors include oxidizing conditions, chloride corrosion, slurry concentration, crystal size, liquid alkalinity, cake moisture, mother liquor removal efficiency, sealing design, and safe continuous operation.
| Application | Material Condition | Separation Purpose |
|---|---|---|
| Calcium hypochlorite crystal slurry separation | Calcium hypochlorite crystals with alkaline mother liquor | Separate wet crystals from the liquid phase |
| Calcium hypochlorite wet cake dewatering | Moist calcium hypochlorite crystals after reaction or crystallization | Reduce free liquid before drying |
| Calcium hypochlorite mother liquor removal | Crystal slurry containing residual process liquor | Improve cake consistency and reduce drying load |
| Calcium hypochlorite washing-stage separation | Washed calcium hypochlorite slurry | Remove residual soluble impurities and wash liquor |
| Calcium hypochlorite fine crystal recovery | Slurry containing fine calcium hypochlorite particles | Recover fine crystals and reduce solids loss |
| Calcium hypochlorite pre-drying separation | Wet calcium hypochlorite cake before dryer feed | Provide more stable feed for downstream drying |
| Calcium hypochlorite process liquor clarification | Mother liquor containing suspended calcium hypochlorite solids | Reduce suspended solids before recycling or further treatment |
| Calcium hypochlorite production wastewater sludge | Waste slurry from calcium hypochlorite processing | Separate solids and reduce liquid load |
A decanter centrifuge is usually installed after crystallization, slurry aging, washing, or concentration steps, depending on the production route.
Typical process route:
Reaction / chlorination → Crystallization or slurry formation → Decanter centrifuge → Wet cake discharge → Drying → Cooling → Packaging
In some projects, the centrifuge may also be used after a washing step:
Crystal slurry → Washing → Decanter centrifuge → Mother liquor removal → Drying
The actual process arrangement depends on feed concentration, crystal size, liquid composition, washing target, final product moisture, and downstream drying requirements.
The calcium hypochlorite slurry enters the rotating bowl through the feed pipe. Under centrifugal force, solid particles move outward and settle on the bowl wall.
The clarified liquid or mother liquor forms an inner liquid layer and leaves through the liquid outlet. The screw conveyor rotates at a differential speed and continuously conveys the wet crystals toward the conical section. The solids are discharged from the solids outlet for drying or further processing.
For calcium hypochlorite slurry, the key is to balance cake moisture, liquid clarity, crystal loss, corrosion resistance, and safe discharge stability.

Calcium hypochlorite slurry can be strongly oxidizing and corrosive, especially in chloride-containing alkaline systems. The wetted parts must be selected carefully.
Material selection should consider:
For this type of process, common stainless steel may not always be enough. Material compatibility should be confirmed before final selection.
Crystal size directly affects separation efficiency, cake moisture, and solids loss.
Coarser and more uniform crystals are easier to separate. Fine crystals may stay in the liquid phase and reduce liquid clarity. If the particle size distribution is too fine, upstream crystallization control or process adjustment may be needed.
The feed solids content affects centrifuge capacity, torque load, and cake discharge stability.
Low-solids slurry may focus more on liquid clarification and crystal recovery. High-solids slurry requires stronger screw conveying capacity and reliable solids discharge.
Lower cake moisture can reduce downstream drying load, but it may require higher centrifugal force, longer residence time, optimized differential speed, and stable feed conditions.
For calcium hypochlorite, moisture control also affects drying safety, product stability, and storage performance.
Calcium hypochlorite processing requires attention to safe enclosed operation. The centrifuge should reduce leakage, splashing, and operator exposure.
