A medium for fast, selective oil-water separation and/or oil absorption includes steel wool modified with a polymer a polymer or a polymer mixture. The polymer or the polymer mixture is adapted such that the medium is a superwetting material that is superhydrophobic and superoleophilic under water. The polymer or the polymer mixture includes polydimethylsiloxane, polytetrafluoroethylene, polyvinylpyrrolidone, or a combination thereof. The solution immersion method used to synthesize the medium requires only a single, simple step and affordable materials and, as a result, is easy to scale up.

An emulsion separation device including a plurality of inclined plates, a buoyancy device, and an electric field generation system. Also disclosed are systems and methods for the separation of an emulsion into a continuous aqueous phase and a continuous oil phase. The systems may include: a vessel having an emulsion inlet, a continuous aqueous phase outlet, and a continuous oil phase outlet. A separation device may be disposed in the vessel, the separation device including: a plurality of inclined plates and a buoyancy device configured to maintain the plurality of inclined plates between the continuous aqueous phase and the continuous oil phase. An electric field generation system may also be provided and configured to expose the emulsion to an electric field.

There is disclosed processes and systems for improving the efficiency of the separation of insoluble contaminants from a fluid in a floatation unit.

An entirely water-based, energy self-sufficient, integrated in-line waste management system is provided for comprehensive conversion of all organic fractions of municipal and wider community waste to fuels suitable for use in transportation, with all solid residues converted to high nutrition compost. The system is based on a combination of pre-treatment, involving alkaline hydrolysis and saponification; three-way separation of the pre-treated waste into different streams that are each directed to suitable further processing including fuel production; which includes biodiesel generation in a continuous-flow catalytic esterification unit, and anaerobic digestion to produce methane or other small molecule biofuel. Remaining solids are converted to compost in a quasi-continuous process.

The present disclosure relates to methods and devices for the separation of blood components including separation by rapid sedimentation, including in an automated fashion.

A filter material for use in fuel-water separation has a particle filtration layer and a coalescing layer downstream of, and coupled to, the particle filtration layer. The particle filtration layer is substantially constructed of binder fibers and media fibers. The coalescing layer has at least 70% glass fibers by weight. As another example, a filter material for liquid fuels has a particle filtration layer and a coalescing layer downstream of the particle filtration layer. The particle filtration layer has binder fibers and media fibers and is substantially free of meltblown materials. The ratio of air permeability of the particle filtration layer to air permeability of the coalescing layer ranges from about 3:1 to about 15:1.

It is provided a water-saturated carbon molecular sieve membrane obtainable by a) providing a hydrophilic carbon molecular sieve membrane (CMSM) comprising pores of a pore size from 0.25 nm to 0.55 nm for molecular sieving, pores of a pore size from 0.55 nm to 0.90 nm for adsorption diffusion and a negligible amount of pores larger than 0.90 nm such that a plot of N.sub.2 permeance versus pressure of permeation at room temperature and at a pressure from 1 to 4 bar has zero or negative slope; and b) humidifying the membrane until obtaining a water-saturated carbon molecular sieve membrane. It is also provided a process for the separation of a gas from a gas mixture with such a water-saturated membrane, and its use for solvent dehydration, and as a membrane reactor.
