摘要： 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.

摘要： A membrane filter is treated with formulated oxide powder and submerged in a liquid to be treated. Colloids in the liquid to be treated are separated and removed, and a colloid-free gap is maintained between the filtered colloids and the formulated oxide powder on the surface of the membrane by adjusting the flux rate which may typically range from 250-750 litres per m2 per hour. A low trans-membrane pressure is maintained across the membrane while the colloid-free gap is maintained, and a low turbidity is achieved in the filtered liquid.

摘要： Various examples are related to smart membranes for monitoring membrane based process such as, e.g., membrane distillation processes. In one example, a membrane, includes a porous surface and a plurality of sensors (e.g., temperature, flow and/or impedance sensors) mounted on the porous surface. In another example, a membrane distillation (MD) process includes the membrane. Processing circuitry can be configured to monitor outputs of the plurality of sensors. The monitored outputs can be used to determine membrane degradation, membrane fouling, or to provide an indication of membrane replacement or cleaning. The sensors can also provide temperatures or temperature differentials across the porous surface, which can be used to improve modeling or control the MD process.

摘要： A membrane container 6 has a casing 10 including a fluid inlet 14 and a fluid outlet 16 and a membrane container body 9 including a plurality of flow paths 11 which is arranged along the flow direction of the treated fluid and in parallel to one another. Each of the plurality of flow paths 11 includes a most upstream portion 11A which is connected to the fluid inlet 14, and a most downstream portion 11C which is connected to the fluid outlet 16. Return portions 15 and 17 configured to reverse the flow direction of the treated fluid are provided between the most upstream portion 11A and the most downstream portion 11C. After passing through the fluid inlet 14, the treated fluid flows from the most upstream portion 11A down to the most downstream portion 11C via the return portions 15 and the upper return portion 17.

摘要： A membrane distillation apparatus includes a housing and an impeller. The housing includes a hot medium compartment, a cold medium compartment, an air gap compartment, a membrane, and a thermally conductive plate. The hot medium compartment includes a hot medium inlet configured to receive a hot medium stream including water. The cold medium compartment includes a cold medium inlet configured to receive a cold medium stream. The membrane defines pores that are sized to allow water vapor originating from the hot medium stream to pass from the hot medium compartment through the membrane to the air gap compartment. The thermally conductive plate and the cold medium stream are cooperatively configured to condense the water vapor from the hot medium stream. The air gap compartment is substantially filled with air and includes a permeate outlet configured to discharge the condensed water vapor. The impeller is disposed within the air gap compartment.

摘要： The present disclosure is directed at a modular apparatus for a saltwater desalinating system, and a method for using same. The apparatus includes multiple internal modules that are compressively coupled to each other. Each of the internal modules includes a pair of rigid end plates located at opposing ends of the internal module, and a stack of membrane bounded compartments that are layered from one of the end plates to the other. The modular apparatus can be used in a membrane based desalination system, which includes concentration difference energy systems, electrodialysis reversal systems, and membrane distillation systems. The modular apparatus helps to mitigate problems such as leakage and buckling in such systems, and can be used to increase membrane packing density and, accordingly, desalination efficiency.
