Abstract: Systems and methods using membrane distillation are provided for desalinating water, for example for the production of potable water, to address freshwater requirements. In an aspect the systems and methods do not require applying an external heat source, or the energy cost of the heating source, to heat the feed stream to the membrane. In an aspect, the sensible heat present in surface seawater is used for the heat energy for the warm stream fed to the membrane, and deep seawater is used as the cold/coolant feed to the membrane to provide the needed temperature gradient or differential across the membrane.

Abstract: This disclosure includes disinfection reactors and processes for the disinfection of water. Some disinfection reactors include a body that defines an inlet, an outlet, and a spiral flow path between the inlet and the outlet, in which the body is configured to receive water and a disinfectant at the inlet such that the water is exposed to the disinfectant as the water flows through the spiral flow path. Also disclosed are processes for disinfecting water in such disinfection reactors.

Abstract: A membrane for membrane distillation processing includes a heating element configured to generate heat when an electrical current is applied to the heating element; a polymeric matrix having pores that allow a vapor to pass through, but not a liquid; and electrical contacts electrically connected to the heating element. The entire heating element is covered by an insulating material to prevent the heating element to directly interact with the liquid processed by the membrane.

Abstract: A method for determining a fouling index ROFix in a filtration system includes supplying a liquid feed across a filtration membrane; measuring an initial filtrate flow rate Q0 of the liquid feed using a cross-flow filtration mode; measuring filtrate volumes Vi at various corresponding times ti using the cross-flow filtration mode; fitting a straight line for the filtrate volumes Vi and the corresponding times ti; and calculating a slope of the straight line. The slope or a parameter related to the slope is the ROFix index, and wherein the cross-flow filtration mode allows the liquid feed to exit the filtration system.

Abstract: Disclosed herein are spacers having baffle designs and perforations for efficiently and effectively separating one or more membrane layers a membrane filtration system. The spacer includes a body formed at least in part by baffles that are interconnected, and the baffles define boundaries of openings or apertures through a thickness direction of the body of the spacer. Alternatively or additionally, passages or perforations may be present in the spacer layer or baffles for fluid flow there through, with the passages and baffles having a numerous different shapes and sizes.

Abstract: A biofouling/biofilm removal system includes a filtration module configured to separate a permeate from a feed; a first inert electrode placed at an inlet of the filtration module; a second inert electrode placed at an outlet of the filtration module; and a power source configured to apply a current between the first and second electrodes. The inlet is configured to receive the feed and the outlet is configured to discard a concentrate, and the current applied between the first and second electrodes initiates electrochemical reactions inside the feed and along a biofilm formed in the filtration module, but not into the permeate.

Abstract: A periodic mesoporous organosilica (PMO) nanoparticle functionalized nanocomposite membrane (NCM) for membrane distillation, the NCM including: polymer fibers such as polyetherimide fibers aggregated into a matrix; and hydrophobic PMO nanoparticles disposed on the polymer fibers. The PMO nanoparticles include a framework connected by organic groups and pentafluorophenyl groups. Good membrane flux and anti-fouling was demonstrated. Membranes can be prepared by electrospinning.

Abstract: An integrated forward osmosis-membrane distillation (FO-MD) module and systems and methods incorporating the module is disclosed providing higher efficiencies and using less energy. The FO-MD module is osmotically and thermally isolated. The isolation can prevent mixing of FO draw solution/FO permeate and MD feed, and minimize dilution of FO draw solution and cooling of MD feed. The module provides MD feed solution and FO draw solution streams that flow in the same module but are separated by an isolation barrier. The osmotically and thermally isolated FO-MD integrated module, systems and methods offer higher driving forces of both FO and MD processes, higher recovery, and wider application than previously proposed hybrid FO-MD systems.
