摘要： In the electrolytic production in water of insoluble metal hydroxide from the metal thereof, more especially of coagulant ferric hydroxide from iron, rectangular channels with flanking ribs provide for pre-established, uniform spacing of the electrode plates and intermediate binary wiping structures. Electrolytic current contact is protected against corrosion by a metallic embossment on the plates. Binary reciprocating wipers are at different wiping levels between successive plates and reversely directed to the opposite surfaces thereof. The wipers are urged against the plate surfaces by bilateral springs, as the surfaces recede due to thinning of the plates as they are consumed. Terminal panels, on which the wipers land after a reciprocating stroke, coextensively bound the plates; protuberances facilitate the transit of a wiper between them. The terminal panels may be employed to concurrently generate oxygen or chlorine as a supplement to coagulant ferric hydroxide.

摘要： Preheated saline water, typically sea or brackish water, is further heated by quanta of steam, passed to it at differential temperatures and pressures and condensed in the saline water. Scale compounds are precipitated and scale-forming bicarbonates decomposed, with the evolution of carbon dioxide, which is gathered and expelled by steam accessory to the quanta of steam. Post-thermal saline water, which is formed, is multistage flash vaporized while self-cooling. The flashed vapors are compressed to form said quanta of steam. After being further cooled while preheating saline water, post-thermal saline water is evaporated in a multistage vapor compression evaporator, producing brine at a high concentration factor. Relative to equilibrium in scale-compound precipitation between 302.degree. F and 347.degree. F, the recovery of fresh water is 70% to 80% for sea water, and 80% to 90% for brackish waters over a wide range of salinity.
摘要翻译： 预热的盐水（通常为海水或微咸水）通过蒸汽量进一步加热，在不同的温度和压力下通入蒸馏水并在盐水中冷凝。 鳞片化合物被沉淀并形成规模的碳酸氢盐分解，随着二氧化碳的逸出，其被蒸汽附件收集并排出到蒸汽量。 形成的后热盐水是自冷却的多级闪蒸。 闪蒸的蒸汽被压缩以形成所述蒸汽量。 在预热盐水进一步冷却后，在多级蒸气压缩蒸发器中蒸发后热盐水，以高浓度因子产生盐水。 相对于302°F和347°F之间的尺度复合沉淀物的平衡，海水中淡水的回收率为70％至80％，咸水中咸水的回收率为80％至90％。

摘要： Water containing dissolved compounds is preheated, and is then pressurized in stages of water pressure, while receiving a quantum of steam. Scale-forming compounds in the water are thermally precipitated, and clarified post-thermal water is formed. This is flash vaporized in stages corresponding to the stages of water pressure, and the flashed vapors are compressed to form each said quantum of steam. Alternately, the flashed vapors themselves comprise each said quantum of steam, by being induced into the water as it flows through an eductor means. Flash-cooled, post-thermal water, substantially devoid of scale-forming compounds, is employed as such, or more generally is evaporated to form fresh water and an end concentrate of dissolved compounds.

摘要： Saline water is preheated by the hot discharges of a vapor compression evaporator, forming distillate and concentrated brine. Carbon dioxide that has been recycled to saline water prevents alkaline scale during the preheat. The saline water is thence further heated by steam which is condensed in it; scale compounds are precipitated and carbon dioxide formed and expelled for recycle. Mother liquor which is separated is flash vaporized, forming cooled mother liquor and vapor. The mother liquor is further cooled while preheating saline water, and is then evporated. The vapor is compressed to form steam for use in the further heating.

摘要： Saline water, typically sea water or brackish water, after deaeration and deoxygenation is preheated, then further heated by steam condensing with the preheated saline water. By the further heating, bicarbonates are thermally decomposed, forming carbon dioxide, while scale compounds, comprising magnesium hydroxide, anhydrite and minor compounds containing silica, iron, alumina, phosphate, etc., are thermally precipitated. Some of the steam is uncondensed and issues from the further heated saline water with included, evolved carbon dioxide. It is condensed in preheating saline water; evolved carbon dioxide is separated from the condensate and recycled to the saline water to prevent alkaline scale in preheating, while condensate is combined with the further heated saline water, forming post-thermal saline water. This is flash vaporized while cooling and the steam is regenerated by compressing the flashed vapors. Cooled, post-thermal saline water is evaporated preferably in a vapor compression evaporator to form fresh water and saline water residuum.
