A nanocarbon immobilized membrane (NCIM) is disclosed. The nanocarbon immobilized membrane is sized to purify different organic-water mixtures. The nanocarbon immobilized membrane can be used to purify solvents, fuels, and other organic compounds. Data using heptane-water, octane-water, fuel-water, and paint thinner-water show 99.9% separation efficiency. High organic flux is also seen at relatively low pressure. This approach has numerous applications, including fuel purification, oil spills clean-up, separation of commercial emulsions, and solvent purification.

Nanocarbon enhanced membrane for purification and dewatering of solvents and fuels

A membrane distillation (MD) system includes a sweep gas MD (SGMD) module and a knockout chamber. The MD module includes a feed inlet, a feed outlet, a condensing media inlet, and a condensing media outlet. The condensing media is sweep gas. The knockout chamber is positioned after the feed outlet. The knockout chamber includes a liquid inlet, a liquid outlet, and a vapor outlet. Direct gas phase stripping within the SGMD module leads to additional water evaporation at the knockout chamber and contributes to enhanced water or VOCs removal of the MD system.

One step integration of membrane distillation with direct air-stripping

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.

Radiative treatment of liquids in desalination and other membrane processes

Membrane distillation (MD) systems include at least two MD modules arranged in series, each of at least two MD modules including a condensing media inlet operable to receive a condensing media and a condensing media outlet, a feed inlet operable to receive a feed media and a feed outlet, and a first heating element positioned and operable to heat a feed prior to or upon introduction of the feed to a first of the at least two MD modules, wherein a stream exiting the feed outlet of the first of the at least two MD modules is introduced to the second of the at least two MD modules. Other MD systems include at least two MD modules arranged in parallel.

Systems and methods for maximizing recovery in membrane distillation

Carbon nanotube (CNT) immobilized membranes for harvesting pure water from air include CNTs incorporated into a layer of super-absorbing polymer. The super-absorbing polymer may be cast over a porous substrate. The super-absorbing polymer binds strongly to water and generates water clusters while the CNTs are operable to interrupt the specific water-polymer and water-water interactions to generate more free water which permeates more easily through the membrane. Methods of forming the CNT immobilized membranes are provided. The CNT immobilized membranes disclosed herein exhibit improved water vapor extraction efficiency, water vapor removal and mass transfer coefficient.
