Top Discharge Centrifuge for Industrial Cleaning Solution Solid Removal

The Top Discharge Centrifuge is designed for batch removal of filterable suspended solids from industrial cleaning solutions, parts-washing liquids, rinse water, and maintenance cleaning baths.

It is suitable when the cleaning liquid contains solid contaminants such as metal chips, abrasive particles, scale, paint flakes, rust particles, carbon deposits, polishing residue, resin fragments, or chemical precipitates. The centrifuge retains these solids inside the basket while clarified liquid passes through the filter medium for collection, reuse, further treatment, or discharge.

The top discharge design is especially suitable for intermittent cleaning systems, maintenance workshops, equipment-cleaning stations, and small-to-medium process lines where operators can stop the machine, open the cover, inspect the captured solids, and remove them manually.

• Parts-washing solution solid removal
• Industrial equipment cleaning liquid recovery
• Metalworking cleaning bath filtration
• Surface-treatment rinse water solids separation
• Grinding and polishing residue removal
• Scale and rust particle removal
• Paint flakes and coating residue separation
• Abrasive media recovery from cleaning solutions
• Reactor and vessel cleaning liquid treatment
• Maintenance cleaning bath clarification
• Batch cleaning solution recycle systems
• Pre-filtration before membrane treatment or wastewater discharge

1. Cleaning Liquid Feeding
   The industrial cleaning solution is fed into the rotating basket lined with suitable filter media.
2. Solid Retention
   Metal fines, scale, abrasive particles, sludge flakes, or other filterable solids are retained inside the basket.
3. Liquid Filtration
   Clarified cleaning liquid passes through the filter medium and is collected through the filtrate outlet.
4. Spin Separation
   Continued rotation improves liquid removal from the captured solids and reduces liquid carryover during discharge.
5. Machine Stop
   After the programmed batch cycle is completed, the basket stops safely.
6. Top Cover Opening
   The cover is opened to allow access to the basket and filter medium.
7. Manual Solids Removal
   Operators remove the retained solids and clean or replace the filter media when required.
8. Liquid Reuse or Further Treatment
   The clarified liquid can be returned to the cleaning system, sent to polishing filtration, or transferred to a wastewater treatment stage.

Removes Filterable Solids Before Liquid Reuse

The centrifuge separates suspended solids from cleaning liquids before they are returned to a wash tank or transferred to downstream treatment. This can help reduce solids buildup in pumps, nozzles, pipelines, and cleaning equipment.

Flexible Filter Media Selection

Filter media can be selected according to the size, shape, and quantity of contaminants. This allows the system to be adapted for metal particles, scale, abrasive residue, coating flakes, or precipitated solids.

Suitable for Intermittent Cleaning Operations

The batch operating mode is well suited to workshop cleaning systems, maintenance cleaning baths, equipment washdowns, and production lines with non-continuous cleaning liquid discharge.

Direct Access for Solids Inspection

The top-opening structure allows operators to inspect the captured solids, assess contamination type, and clean the basket or replace the filter medium as needed.

Cost-Effective Pre-Treatment for Downstream Systems

Removing coarse or filterable solids upstream can reduce the load on bag filters, cartridge filters, membranes, or wastewater treatment equipment.

To recommend a suitable Top Discharge Centrifuge, please provide:

• Cleaning solution composition
• Type of solid contaminant
• Particle size or expected solids range
• Solids concentration
• Presence of oil, grease, or surfactants
• Feed temperature and viscosity
• Required cleaning liquid recovery rate
• Batch volume or required throughput
• Required filtrate clarity
• Corrosion condition
• Cleaning and maintenance requirement
• Installation area and available utilities
• Explosion-proof requirement, if applicable

Can this centrifuge remove oil from industrial cleaning solution?

It is mainly designed to remove filterable solids. Free oil may require an oil skimmer or coalescer upstream. Stable emulsified oil generally requires a different treatment method.

Can clarified cleaning liquid be reused?

It can be collected for reuse when the remaining liquid quality meets the process requirement. Further polishing filtration or treatment may still be needed depending on the cleaning standard.

What solids can be removed?

Typical solids include metal chips, abrasive particles, scale, rust, paint flakes, carbon residue, polishing debris, and filterable precipitates.

Is the centrifuge suitable for continuous cleaning systems?

It is a batch machine. It works best for intermittent or buffered cleaning-liquid discharge. A buffer tank can be used where cleaning liquid is generated continuously.

How is the captured sludge removed?

After the batch cycle, the machine stops and the top cover is opened. The retained solids are removed manually from the basket and the filter media can be cleaned or replaced.
