Membrane Filtration Technology

Membrane Filtration Technology

Membrane technology can increase process performance, reduce costs, save energy and water, improve or create new sustainable revenue streams from By-products.

Benefits of using membrane technology include:

  • Separation without chemicals
  • Selective cut off
  • Small footprint
  • Wide range of applications
  • A physical separation process without the sensitivities of biological processing

Controlled separation takes place when pressure and velocity is applied to liquid flowing across a membrane surface.

Depending on the “molecular weight cut off” (MWCO) of a membrane, it is possible to isolate a wide rang of constituents in a feed stream including suspending solids, fibres, particles, protein, bacteria, virus, colour, dissolved salts and metal ions.

The technique produces a consistent, stable output which is ideal for quality sensitive and water recycling applications.  The physical simplicity of the process offers considerable nevironmental and operational advantages.
