Abstract: A composite polyamide reverse osmosis membrane and method of producing same. In a preferred embodiment, the membrane is made by coating a porous polysulfone support with an aqueous solution containing 2 wt % m-phenylenediamine (MPD), and 0.1 wt % di(ethylene glycol) hexyl methyl ether. Next, the excess solution is removed, and the coated support is dipped in 0.1 wt % organic solvent solution of trimesoyl chloride (TMC) in a mixture of alkanes having from 8 to 12 carbon atoms. After draining the TMC solution off, the resulting composite membrane is air dried and then rinsed in a basic aqueous solution. The resultant membrane exhibits a flux of 21.3 gfd and a salt rejection of 98.9% when used at 225 psi for an aqueous solution containing 2000 ppm of NaCl.

Abstract: A process and system for purifying water is disclosed. For example, in one embodiment, the process may be used to remove a divalent salt, such as calcium sulfate, from a water source in order to prevent the divalent salt from precipitating during the process. The water source, for instance, may be fed to an ion separating device, such as an electrodialysis device. In the electrodialysis device, an ion exchange takes place between the divalent salt and another salt, such as a monovalent salt to produce two concentrated salt streams that contain salts having greater solubility in water than the divalent salt. In one embodiment, the two salt streams that are produced may then be combined to precipitate the divalent salt in a controlled manner. During the process, various other components contained within the water feed stream may also be removed from the stream and converted into useful products. In one particular embodiment, the process is configured to receive a byproduct stream from a reverse osmosis process.

Abstract: A method of treating water for municipal use comprises treating the feedwater stream on the feed side of a reverse osmosis membrane with a non-oxidizing, bromine-containing biocide in the substantial absence of a reducing agent, such that biofouling of the membrane is reduced or prevented, and measuring the produced water stream on the permeate side for the presence of bromine-containing compounds. Advantages may include preservation of the membrane, production of water that meets applicable regulations for safe drinking, and simplified processing without additional steps to remove the biocide or its degradation products from the produced water.

Abstract: The invention concerns a centrifugal filtering device for filtering a fluid. The device comprises a rotatable inner casing forming an inner space and a rotatable outer casing forming an outer space. The device further comprises a fluid inlet, at least one filter and drive means. The drive means is configured to rotate the inner casing to create a centrifugal pressure. The pressure forces a part of the fluid contained in the inner space through the filter and to a radially outer position of the outer space. The filtered fluid forms a filtrate, the filtrate having a kinetic energy. The outer casing is configured to transport the filtrate from the radially outer position to a radially inner position of the outer space, permitting transfer of the kinetic energy from the filtrate to the outer casing, thereby permitting regaining of mechanical energy.
