BMEX system Technical data

BMEX system
The BMEX system consists of a BME pump creating
the flow through the membranes as well as the design
pressure.

The X-Changer converts the energy from the concentrate
Q × H of the membranes into the feed stream to
the membrane.

The pressure loss in the X-Changer is equalized by the
BM pump and VFD frequency converter holding the
desired pressure for the RO process.

Corrosion resistance
All parts that come in contact with the pumped liquid are made from stainless steel, polymer and ceramic, ensuring resistance to corrosive and low-viscosity fluids, e.g. seawater and brackish water.

High quality products
The BMEX system offers years of trouble free operation at a low cost of operation with limited maintenance effort.

Compact design
The BMEX system has a very small foot print giving system builders a free hand to design more compact systems.
