The alternative to traditional water softening

With nanofiltration, ions dissolved in water are held back to a lesser degree than with reverse osmosis. Typical salt retention rates are between approximately 80 - 85 %. Multivalent ions (e.g. Ca and Mg) are retained better than univalent ions (e.g. Na, K). Nanofiltration systems are often a good alternative to reverse osmosis systems because there is no need for time-consuming regular regeneration with large amounts of salts.

Cut costs

If lower salt retention is acceptable, nanofiltration is a suitable choice. These systems can run at lower operating pressures, a smaller booster pump can be used, all of which reduces costs. Not only does this reduce the cost of your initial investment but more importantly ongoing operating costs come down too. Does this sound good to you? Want to know more?

Nanofiltration System DULCOSMOSE NF

Permeate outputs from 1 to 50 m3/h, higher outputs possible on request

As a nanofiltration system, the DULCOSMOSE NF, a compact and value-for-money unit, can handle partial desalination in industrial applications. Maximum permeate output at low operating pressures ensures low operating costs thanks to the "ultra low pressure" diaphragm. more

Features and Benefits

  • Efficient operation with a low pressure membrane with outputs of up to 85% and high salt retention rates of up to 90% (depending on the type of membrane used).
  • Reduced maintenance and service costs, as well as long membrane service lives, thanks to integrated cleaning concepts and flushing options.
  • Optional permeate flushing of the entire system, including the membranes, after switching off to avoid deposits and extend the life of the membranes.
  • Best ProMinent manufacturing quality: High proportion of in-house manufacturing.
  • Pure quality: Use of long-life, high-quality components.
  • Service-friendly construction of systems on a corrosion-resistant powder-coated steel or stainless steel frame.
  • Simple and safe to operate: Microprocessor control with direct connection option for peripheral system components and integrated conductivity measurement with plain text display in the graphic display.
  • One-stop shop: no interface problems, smooth running with short times between definition of the task to joint commissioning and on-site system supervision with our global subsidiaries.
