Abstract: The present disclosure relates to a hybrid AD-DCMD desalination system, where two subsystems, such as AD and DCMD, are integrated synergistically to maximize freshwater production. The waste heat released from an AD condenser is used to drive the DCMD subsystem in a first configuration of the hybrid AD-DCMD system, while another configuration relies on the heat released due to an exothermic adsorption process in an adsorption bed. The DCMD subsystem is included to exploit the waste heat of the AD subsystem to enhance performance. In both these configurations, seawater is used to release the heat from the AD subsystem, which is then fed into the DCMD subsystem. The hybrid AD-DCMD system configurations demonstrate improved performance in terms of GOR, specific daily water production (SDWP), and freshwater cost reduction.

Abstract: A multi-layer membrane which has a mixed polyamide selective layer supported on a porous polysulfone layer. The mixed polyamide selective layer includes reacted units of a polyfunctional acyl halide (e.g. trimesoyl chloride) and a diamine mixture containing 4,7,10-trioxa-1,13-tridecanediamine and a cyclic diamine (e.g. piperazine). Methods of fabricating the multi-layer membrane via techniques such as phase inversion and interfacial polymerization are described. The inventive membrane is evaluated on its water flux and salt rejection (e.g. sulfate and chloride salts) capabilities. A water desalination system containing the multi-layer membrane(s) is also provided.

Abstract: The invention relates to a generator and its operation and use for generating toroidal and spatial vortices in a liquid. It comprises a rotationally symmetrical stator housing with an inlet opening and an eccentric outlet opening. It further comprises a rotor rotatably arranged in the stator housing with radially outwardly extending channels in constant fluid connection to the inlet opening. The rotor comprises a rotor disc, radially outside of the rotor with a side surface with inner notches in fluid connection to the rotor channels. The stator housing comprises a stator disc comprising a side surface with stator notches. When these notches face each other due to rotation of the rotor disc, a periodical liquid flow from the inner notches to the stator notches is formed and toroidal vortices are generated in the portioned liquid by shear stress as the portions of liquid move back and forth in the notches.

Abstract: A high salinity feed water such as seawater is treated to produce a reverse osmosis (RO) concentrate and an RO permeate. Optionally, some or all of the RO concentrate may be filtered to produce a nanofiltration (NF) permeate. Optionally, some feed water can also be filtered to produce NF permeate without first being concentrated by RO treatment. The NF permeate, or a blend of the RO permeate and NF permeate, may be used to produce a product water for injection into an oil-bearing reservoir to enhance oil recovery. Optionally, the product water may have salinity greater than the feedwater, or at least 30 g/L. The product water may have hardness of less than 20 mg/L.

Abstract: A water purification electrode composed of a porous carbon material is disclosed. The electrode may be used as a flow-through cathode in an electro-peroxone process providing high H2O2 production activity for electrochemical wastewater treatment. The porous carbon material is a binding agent-free carbon structure that enables H2O2 to be electro-generated in situ at cathode. The porous carbon material may be synthesized from resorcinol and can provide a relatively large reaction surface area of 200-800 m2/g. The porous carbon material also achieves low energy consumption as well as a wide pH working range, making it suitable for treating many types of organic, inorganic, and biological contaminants in water. The electrode may be integrated with an anode, ozone generator, and other components into a compact, integrated water purification system.
