Ultrafiltration - versatile membrane technology

Ultrafiltration is used in many different areas and industry sectors for wastewater and water treatment. EnviroChemie is your partner for reliable solutions for sustainable water treatment using Envopur® ultrafiltration processes.

To list a few examples, this special membrane technology is used to retain the biomass, can extend the service life of degreasing baths, is applied in the recycling processes for wastewater that is created by vibratory finishing, and splits oil/water emulsions, such as compressor condensate. These are only a few areas of application in which Envopur® ultrafiltration processes close cycles in water management efficiently and ecologically.


Ultrafiltration generally distinguishes itself from microfiltration by the pore size of the membrane that is used in the modules. The pores of the membrane measures less than 0.1 µm and are therefore smaller than microfiltration, however they are larger than nanofiltration.

An additional distinct feature of the ultrafiltration membranes is their asymmetric structure. The membrane is made up of a release layer with pores in the submicron area and a porous support layer that is solely used for support. The membranes used in microfiltration on the other hand are symmetrical and porous, meaning the width of the pores in the membranes does not vary.

The processes developed by EnviroChemie for Envopur® ultrafiltration have been designed in a way that properly separates the captured contaminants through the filtration membrane and delivers optimum results for you in terms of wastewater and industrial water treatment.
