Microfiltration – reliable preliminary stage for water purification
Microfiltration is a mechanical filtration process in which particles, solids and microorganisms are removed from liquids. With a pore size of around 0.1 to 10 micrometers, microfiltration is ideal for the pre-treatment of process water, as a protective stage before ultrafiltration or for the direct separation of suspended solids. Dissolved substances are retained in the water, while unwanted solids are reliably retained.
Ultrafiltration – precise separation down to the submicrometer range
Ultrafiltration is ideal for separating emulsions, oils, microorganisms and the finest particles down to a pore size of approx. 0.01 micrometers. It enables particularly thorough purification of process and waste water without removing dissolved salts or smaller molecules. Ultrafiltration is used, for example, in degreasing bath treatment, in the separation of oil-water mixtures and for the recovery of valuable components – economically and reliably.
Nanofiltration – selective separation at molecular level
Nanofiltration works with even finer pores (approx. 0.001 micrometres) and is therefore ideal for retaining small organic molecules, hardness constituents and selected salts. It is often used for the treatment of process water, for partial desalination or as an upstream process for reverse osmosis. Nanofiltration combines high retention values with comparatively low energy requirements – perfect for applications with high demands on water purity and resource efficiency.
