Abstract: A filtration apparatus includes a tubular casing having a longitudinal axis and first and second casing ends. A plurality of partition plates are positioned in the casing and sealed thereto to thereby define an intake collection chamber between a first of the partition plates and the first casing end, a discharge collection chamber between a second of the partition plates and the second casing end, and a reject collection chamber opposite the second partition plate from the second casing end. A plurality of elongated filtration membrane stacks are positioned side-by-side in the casing generally parallel to the longitudinal axis. Each filtration membrane stack includes an intake end which is fluidly connected to the intake collection chamber, a discharge end which is fluidly connected to the reject collection chamber, and a permeate channel which extends between the first and second ends and is fluidly connected to the discharge collection chamber. The filtration apparatus further includes an intake pipe having a first end that is fluidly connected to the intake collection chamber and a second end that is fluidly connected to a first connector which is located proximate the second casing end; a discharge pipe having a first end that is fluidly connected to the discharge collection chamber and a second end that is fluidly connected to a second connector which is located proximate the first connector; and a reject pipe having a first end that is fluidly connected to the reject collection chamber and a second end that is fluidly connected to a third connector which is located proximate the first and second connectors. In use, a fluid to be filtered is communicated to the intake collection chamber through the intake pipe and is separated by the filtration membrane stacks into a permeate which is discharged from the discharge collection chamber through the discharge pipe and a reject fluid which is discharged from the reject collection chamber through the reject pipe.

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.

The process includes contacting a porous support membrane with an aqueous phase containing a polyamine and a flux enhancing combination, which includes a metal chelate additive containing a bidentate ligand and a metal atom or metal ion and a dialkyl sulfoxide, to form a coated support membrane, and applying an organic phase containing a polyfunctional acid halide to the coated support membrane to interfacially polymerize the polyamine and the polyfunctional acid halide to form a discrimination layer of the thin film composite membrane. Also provided are the membranes prepared by the methods and reverse osmosis modules containing the membranes.
