摘要： A system and method for treating water containing at least one contaminant. The system and method include a water treatment module such as a reverse osmosis unit. An electrochemical contaminant detection system is positioned in the waste water stream of the water treatment module. The contaminant detection system includes a contaminant sensor and a water quality sensor module. The contaminant sensor measures the concentration of the contaminant in the waste water stream and the water quality sensor module measures one or more water quality parameters of the waste water stream. A processor uses an algorithm to determine the concentration of the contaminant in the feed water based on the measurements of the contaminant sensor and water quality sensor module.

摘要： An electrochemical system has a first reservoir receiving a feed stream. The feed stream includes a solvent and a solute different than the salt. A second reservoir receives a brine stream with a higher salt concentration higher than the feed stream. Electrodes contact a loop of redox-active electrolyte material causing reversible redox reactions. The reactions cause the loop to accept a first ion from the salt in the first reservoir and drive a second ion into the brine stream in the second reservoir. Three ionic exchange membranes of alternating type define the first and second reservoirs. A concentrate stream is output from the first reservoir, the concentrate stream having a second solute concentration greater than the first solute concentration.

摘要： A water stream is passed between two juxtaposed similar ion exchange membranes (AEMs or CEMs), forming an ion depletion and ion enrichment zones when an electric field is applied. As cations are selectively transferred through the CEMs, for example, anions are relocated in order to achieve electro-neutrality, resulting in the concentration drop (increase) in ion depletion (enrichment) zone. Trifurcation of the output channel allows collection of concentrated, dilute and intermediate streams, with the intermediate stream serving as input to the next stage of a serialized implementation.

摘要： A liquid electrolyte can be desalinated and purified using a system that includes a first electrode and a configuration selected from (a) a second electrode and at least one distinct ion-selective boundary and (b) a second electrode that also serves as the ion-selective boundary. The ion-selective boundary is contained in the liquid conduit adjacent to a porous medium that defines pore channels filled with the liquid and that have a surface charge, and the charge of the ion-selective boundary and the surface charge of the pore channels share the same sign. A liquid including at least one charged species flows through the pore channels, forming a thin diffuse electrochemical double layer at an interface of the liquid and the charged surface of the pore channels. A voltage differential is applied between the electrodes across the porous medium to draw ions in the liquid to the electrodes to produce brine at the electrodes and to create a shock in the dissolved-ion concentration in the bulk volume of the liquid within the pore channels, wherein a depleted zone with a substantially reduced concentration of dissolved ions forms in the liquid bulk volume between the shock and the ion-selective boundary.

摘要： Various aspects of the present disclosure are directed toward apparatus and methods method for filtering water fluid by screening ionic minerals including sodium chloride from the water fluid. In one embodiment, the water fluid is passed into a work zone defined at least in part by oppositely-arranged first and second porous structures, each of which have a plurality of gated channels. The water fluid is processed in the work zone by applying respective electric voltages to electrically bias the first porous structure and the second porous structure. The respective electric voltages deplete sodium chloride ions in the water fluid in the work zone due to ion-flux continuity. In response to processing of the water fluid, ion-filtered water is collected from the work zone.

摘要： There is a method described of treating tailings which are composed of at least some water and clay particles. Within the tailings, at least some water molecules are weakly bond to the clay particles to form a gel like fluid from which water does not readily separate. An alternating current is applied to the tailings to change the electro-chemical properties of the tailings to reduce the weak bonding between the water and the clay particles so that water within the treated tailings is able to separate. Water within the treated tailings is then allowed to separate without further application of electricity. In some embodiments, the treated tailings are allowed to separate through evaporation. Liquid tailings may also be treated with alternating current by applying alternating current to the liquid tailings at a voltage gradient range of 1 to 5 V/cm for a total duration of 24 to 300 hours. The application of alternating current may further comprise applying alternating current at a frequency of 1 to 30 Hz.
