Membrane Filtration – Microfiltration (MF)
Microfiltration is employed in both the treatment of drinking water and industrial and municipal wastewater.
The membranes have pore sizes ranging from 0.1-3 micrometres and remove all particles of this size. Bacteria and parasites are reliably captured, however, no guarantee can be given with regard to the filtration of viruses. MF operates in a pressure range of between 0.2 and 1 bar. The membrane materials consist of PVDF (polyvinyldifluoride), PTFE(Teflon), PES (sulphonated polyethylene), etc.
WABAG has utilised microfiltration in a variety of treatment applications, e.g. for water derived from the flue gas scrubbers in waste incineration plants, municipal wastewater, process water for industrial operations and landfill seepage water as well as for advanced pre-treatment for Reverse Osmosis desalination plants.
A further area of application is the elimination of humic matter using microfiltration and integrated precipitation with aluminium salts.
