KOMPasep-C ultrafiltration units: Recycling and disposal of up to 90°C (194°F)

Application fields

The ultrafiltration systems of the KOMPasep-C line are employed for the recycling and disposal of different production solutions or production waste waters with temperatures of up to max. 90°C by means of ceramic membranes.

  • Degreasing and washing water
  • Cooling lubricants
  • Drawing and rolling emulsions
  • Frictional grinding water and dispersions
  • Photoresist waste waters
  • Recycling of crack detection oil from rinsing waters
  • Laundry waste waters
  • Diverse special applications

General process description

Ultrafiltration is a physical separation process. It separates aqueous dispersions and emulsions. The medium to be separated is guided past a membrane at high speed and under a certain pressure (cross-flow technology). The pore size of the membrane is dimensioned so that small molecules, for example water and dissolved substances (permeate), can pass through and larger ones (retentate/concentrate) are retained. During recycling, the separation process basically runs as in the disposal.

Description of system

The KOMPasep-C series systems are constructed as follows:
Collecting vessel; prefiltration with coarse filter (optional); working container; ultrafiltration system; rinsing container.

Under process-related and energetic aspects, these systems are offered in two designs, depending on their size, i.e. in a compact design and in a loop design (feed and bleed).

The operation of these systems is subdivided into the following main steps:

  • Separation: Filtration with discharge of the permeate and feeding from the collecting vessel into the working container
  • Thickening: Filtration with discharge of the permeate without feeding for the final concentration of the concentrate (e. g. oil content approx. 30 – 40%)
  • Rinsing: Cleaning of the membrane after lapse of a working cycle


  • High throughput
  • Cost savings due to recycling or reduction of costs for disposal
  • Preassembled systems with functions tested
  • Compact design
  • Nearly all systems can be expanded by additional modules with the same periphery
  • Modern control concept with central PLC unit
  • Saving of energy by the use of loop technology
  • Wide spectrum of application by the use of different membrane materials
  • Long service life of the employed membranes
  • Optimal concentration or yield
