摘要： In a desalination system, water is treated, for example by reverse osmosis, to produce desalinated product water and a reject stream. Salt from the reject stream is transferred to a flow of low salinity wastewater, such as effluent from a municipal wastewater treatment plant. For example, the reject stream may be fed to the high salinity cell in an electrodialysis (ED) unit. The adjacent low salinity cell receives the low salinity wastewater. The high salinity and low salinity cells are separated by ion exchange membranes. The salty wastewater is discharged, for example to the ocean. The salt-reduced reject stream is treated to extract more product water from it, for example by recycling it to the feed water. Less feed water is needed to produce a given volume of product water. If a thermal desalination unit is combined with divalent ion selective ion exchange membranes, then scaling is reduced.

摘要： A multistage thermal desalination system, together with its associated method of use, allows de-scaling of subsystems exposed to saturated saltwater by alternating the saturation stage of the process between two neighboring physical desalination stages. The desalination system is provided with at least one transfer conduit, at least one pump, and valving to permit saltwaters being desalinated by higher and lower stage desalination subsystems to be swapped. By replacing the saturated saltwater in a higher salt concentration desalination subsystem with lower salt concentration saltwater, the scaling in higher salt concentration desalination subsystem is reduced while the saturation load is placed on another of the desalination subsystems.

摘要： Oil sands process water (OSPW) is directed to an evaporator that evaporates the OSPW and produces steam and a concentrated brine. The OSPW includes alkalinity and calcium hardness. To inhibit calcium carbonate scaling of the evaporator, magnesium oxide is mixed with the OSPW, resulting in the precipitation of magnesium hydroxide which acts as a seed material for calcium carbonate precipitation to prevent fouling. The process crystallizes the calcium carbonate and the mixture of magnesium hydroxide and calcium carbonate crystals are circulated through the evaporator as well as recirculated to a point upstream of the evaporator.

摘要： A distiller for processing liquid influent, including a heating chamber. An evaporation arrangement can be positioned above the heating chamber and can include spaced apart evaporation surfaces forming a bottom evaporation stage, multiple intermediate evaporation stages, and an upper evaporation stage. The bottom evaporation stage can be in thermal contact with the heating chamber, and the multiple intermediate and upper evaporation stages can be sequentially positioned above the bottom evaporation stage one above another. The bottom and intermediate evaporation stages can evaporate at least a portion of the liquid influent applied thereon forming vapor and heating the stage positioned above with the vapor. A liquid delivery system can provide the liquid influent to the upper evaporation stage for initial evaporation, and transfer at least a portion of the liquid influent in the upper evaporation stage and intermediate evaporation stages downwardly in sequence to a stage below until reaching the bottom evaporation stage for sequential evaporation at each evaporation stage. A solids transfer system can move solids on an evaporation surface of the bottom evaporation stage remaining from evaporated liquid influent to the heating chamber for combustion and providing heat.

摘要： A desalination system includes a water tank, a water-repellent particle layer located at a lower portion of the tank and composed of water-repellent particles, and a devolatilizing layer located below the water-repellent particle layer. Liquid is introduced to the tank, the introduced liquid is heated to be evaporated into water vapor, and the water vapor passes through the water-repellent particle layer and is liquefied at the devolatilizing layer, so that fresh water is obtained from the liquid. The desalination system further includes a liquid level controller for determining a level of the liquid introduced to the tank in accordance with information on relationship between information corresponding to an amount of the liquid introduced to the tank and a surface level of the liquid in the tank, and an introduced amount controller for adjusting the amount of the liquid introduced to the tank in accordance with the determined liquid surface level.

摘要： A liquid concentrator having an evaporator assembly and a cyclonic separator includes features designed to improve the performance of the liquid concentrator. A settling chamber is separated from a sump of the cyclonic separator. A liquid inlet opening into a mixing chamber of the evaporator injects wastewater at low pressures. Features to aid in the cleaning of the liquid concentrator include easy open doors and clean water injection ports for cleaning interior portions of the liquid concentrator. In one feature a settling tank is disposed below the cyclonic separator and has a width that is larger than the width of the cyclonic separator. In another variation, the cyclonic separator has a tubular body with an interior that is substantially unobstructed between an inlet from the evaporator assembly and an exhaust outlet. In yet another variation, the cyclonic separator has an upper chamber that is separated from a lower chamber.
