The Envopur® ultrafiltration processes developed by EnviroChemie are designed to ensure the targeted separation of introduced contaminants by the filtration membrane and to deliver optimal results in the treatment of wastewater or process water.
Membrane separation processes use a special membrane to retain dissolved and undissolved substances. The substances retained by the membrane are usually concentrated in the concentrate stream, while the filtrate is largely free of them. The membrane body of an ultrafiltration consists of a release-active layer with pores in the submicron range and an open-pored support layer. Pores with a size of 0.01 - 0.01 µm are used for ultrafiltration. Due to the pore size of the membrane, only certain molecules can pass through the membrane, thereby separating dirt particles.
Ultrafiltration enables the separation of colloidal and undissolved substances. This allows for the retention of microparticles, suspended solids, hydrocarbons and bacteria, for example. The limit values of COD and BOD can be met using the Envopur® ultrafiltration treatment.
This special membrane process is used, for instance, for the retention of biomass, it can prolong the service life of degreasing baths, it is used in the recycling of wastewater generated during vibratory grinding, and it splits oil-water emulsions, such as compressor condensate. Ultrafiltration membranes also provide an absolute particle barrier to microplastics and reliably retain them. These are just a few areas of application in which Envopur® ultrafiltration processes can close circuits in water management in an economically and ecologically sensible manner.
