Membrane filtration uses an engineered semi-permeable barrier to separate very small particles from water. Industry has divided membrane filters into several classes based
on ranges of particle rejection, which is determined by the pore size of the membrane.

As pore size decreases, more pressure is needed, increasing power requirements. Care must be taken to configure the optimal membrane for each application, achieving the desired level of filtration with minimal power consumption and reduced cleaning and chemical costs.

There is no “one size fits all” membrane solution, and no single membrane element offers a provably superior technology for every membrane category. As a systems integrator, Layne delivers the optimal custom-engineered system for every client's unique needs.

Membrane filtration classes are as follows:

  • MF - microfiltration system for filtration of suspended particles
  • UF - ultrafiltration system for filtration of macromolecules
  • NF - nanofiltration system for filtration of small molecules, divalent salts and dissociated acids
  • RO - reverse osmosis system for filtration of monovalent salts and undissociated acids
