Ultrafiltration for Industrial Parts Cleaning – Extend Wash Bath Service Life
In industrial parts cleaning, metalworking and automotive production, consistently high component cleanliness is essential. However, washing and degreasing baths are continuously contaminated during operation by oils, greases, cooling lubricants, metal particles, fine solids and stable emulsions.
MKR ultrafiltration systems clean these process media in a closed-loop operation. Ceramic membranes separate contaminants from the washing medium, while the cleaned medium can be returned to the process depending on the application. This helps extend wash bath service life, reduce bath changes and support stable cleaning processes.
MKR develops ultrafiltration systems for industrial applications where process reliability, media care and economical operation are key.

Contaminated Wash Baths in Industrial Parts Cleaning
In cleaning, washing and degreasing processes, contaminants continuously enter the process medium during production. Especially in metalworking, surface treatment and the automotive industry, wash baths are exposed to high contamination loads from:
- oils and greases
- cooling lubricants
- metal particles and fine solids
- stable emulsions
- dirt and process residues
These substances reduce the cleaning performance of the wash bath. Typical results include inconsistent cleaning quality, increasing maintenance effort and more frequent bath changes.
Typical Consequences in Practice
- decreasing component cleanliness
- higher reject rates and rework
- frequent bath changes
- production interruptions
- increasing disposal and operating costs
- higher chemical and water consumption
The result: decreasing process stability and increasing cost pressure.
Which Applications Are Suitable for Ultrafiltration?
Ultrafiltration is suitable for industrial applications where washing, degreasing or process media need to be cleaned, stabilized and reused depending on the required quality.
Requirements for Wash Bath Care
Modern production processes require reliable systems for wash bath care. The decisive factor is not only the filtration of individual particles, but the continuous stabilization of the entire process medium.
Technical Requirements
- consistent cleaning quality
- reliable separation of oils, particles and emulsions
- stable operation even with changing contamination loads
- integration into existing cleaning systems
- automated process control
Economic Requirements
- longer wash bath service life
- fewer bath changes
- reduced disposal effort
- shorter downtimes
- transparent economic evaluation
Sustainability Requirements
- lower freshwater demand
- reduction of liquid residual streams
- resource-efficient use of process media
- improved circulation of process water and washing media
The Solution: MKR Ultrafiltration with Ceramic Membranes
MKR ultrafiltration systems continuously clean washing and degreasing baths in closed-loop operation. The contaminated medium is removed from the process, passed through a ceramic membrane and then returned as cleaned permeate.
Oils, greases, emulsified components, fine solids and other contaminants are concentrated in the retentate and discharged in a controlled manner.
What Ultrafiltration Achieves in Wash Baths
- removal of oils and greases
- separation of fine particles
- reduction of stable emulsions
- return of the cleaned medium
- stabilization of wash bath quality
- extension of bath service life
The benefit: The wash bath remains usable for longer and cleaning quality is stabilized during ongoing operation.
How Does Ultrafiltration Work in Wash Bath Care?
In ultrafiltration, the contaminated wash bath is passed under pressure over a ceramic membrane. The membrane acts as a selective separation layer.
The cleaned medium passes through the membrane as permeate. Retained contaminants are collected and concentrated in the retentate.
Permeate is the cleaned fraction of the washing medium that passes through the membrane and can be returned to the process depending on the application.
Retentate: Concentrated Contaminants
Retentate contains retained substances such as oils, greases, particles and emulsified components. It is discharged in a controlled manner and then further treated or disposed of.
Continuous Closed-Loop Operation
The ultrafiltration system operates parallel to the production process:
- removal of the contaminated washing medium
- filtration through ceramic membranes
- return of the cleaned permeate
- discharge of the retentate
- automatic membrane cleaning depending on the system concept
This allows continuous wash bath care without unnecessarily interrupting the cleaning process.
Consistent cleaning quality over longer service life - through continuous wash bath care from MKR
Why Ceramic Membranes Are Crucial for Industrial Processes
Industrial washing and degreasing baths place high demands on filtration technology. Temperature, chemistry, pressure, particle load and emulsions can quickly push simple filter systems to their limits.
That is why MKR uses ceramic membranes. They are particularly robust and suitable for demanding industrial applications.
