Abstract
Radiative heating and radiative feed modification systems and methods using microwave, radio frequency, magnetic field and ultrasound in membrane separation processes including membrane distillation (MD), reverse osmosis, forward osmosis and pervaporation are disclosed. Membrane distillation systems include at least one MD module, the MD module having at least one membrane, a feed inlet operable to receive a feed media and a feed outlet, and a radiative energy source operable to apply radiation to a feed media entering the feed inlet.
Claims19
A membrane distillation (MD) system comprising at least one MD module, the MD module comprising at least one membrane, a feed inlet operable to receive a feed media and a feed outlet;
- and a radiative energy source operable to apply radiation to a feed media entering the feed inlet.
A method for purifying a feed stream comprising the steps of providing at least one membrane separation device comprising a feed inlet and feed outlet, subjecting the feed stream to radiation selected from the group consisting of microwave, RF, magnetic field and ultrasound radiation prior to or upon introduction of the feed stream to the at least one membrane separation device, introducing the feed stream to the at least one membrane separation device, and recovering a stream from the feed outlet of the at least one membrane separation device.
