Microfiltration

Microfiltration (MF) uses physical separation to remove suspended solids and bacteria from water streams through a membrane porosity of between 0.1 to 10 μm. MF does not remove dissolved contaminants.

Microfiltration is used in a range of water treatment applications:

  • Potable water treatment
  • Pre-treatment for the removal of suspended solids that can foul downstream NF or RO membranes
  • Clarification and sterilisation in food, beverage and pharmaceutical industries
  • Wastewater treatment

Veolia Water Technologies South Africa is a leader in microfiltration, with a complete range of membranes available. We provide turnkey MF solutions for industries and municipalities, which can be both modular or part of an in-ground civils-based plant. This includes customised operations & maintenance contracts and quick turnaround on new replacements MF membranes.

Ceramic Membrane Technology from Veolia

Veolia’s ceramic membrane range combines innovative modular designs and unique materials of construction to provide exceptional microfiltration performance.

This proprietary microfilter design uses large-diameter ceramic monolith membranes that reduce the overall footprint of installed equipment.

  • Robust, large-diameter monoliths as membrane supports
  • High chemical and abrasion resistance
  • Very high packing density with large membrane area in a single membrane module (10.5 m2)
  • Low fouling properties
  • Suitable for elevated temperature operation & processing of non-aqueous media
  • Reduces power consumption through reduced cross-flow velocity operation without adverse membrane fouling

Microfiltration in your water stream:

As with other membrane filtration processes, microfiltration entails the introduction of a feed stream into the MF membrane under pressure. The larger pore sizes of microfiltration membranes mean less pressure, and thus energy, is required to extract the permeate, and is thus is extremely cost effective in the relevant micron range.

In terms of molecular weight, membranes can separate macromolecules of molecular weights less than 100 000 g/mol. The filters used are specially designed to prevent particles like sediment, algae, protozoa and large bacteria from passing through.

When used for potable water treatment, the membranes are a key step in uptake water primary disinfection. When treating secondary wastewater effluents, MF is used to remove turbidity and provides treatment for disinfection.
