This document describes systems and methods for treating and recovering water from feed solutions using a multilayer module with an expansion chamber. The multilayer module comprises a feed spacer layer, a permeate spacer layer and a membrane layer, wherein water vapor evaporated from the feed solution in the feed spacer passes through the membrane layer into the permeate spacer layer. The expansion chamber receives the water vapor from the permeate spacer layer and the feed solution from the feed spacer layer.

The device has potential application prospect.

Introduced here are treatment systems and associated processes for treating water using magnetic fields. A treatment system can comprise a hydromagnetic resonator that creates the magnetic fields through which water can be directed. A hydromagnetic resonator can include at least one expansion chamber that provides a tortuous path along which water is able to flow through a magnetic field created by an arrangement of permanent magnets and at least one convergent-divergent nozzle designed to accelerate the flow of waterpassing through a throat segment. Water directed through a hydromagnetic resonator will be magnetically treated while flowing through the magnetic field created by the arrangement of permanent magnets within each expansion chamber and then pressurized while flowing through the throat segment of each convergent-divergent nozzle.
