摘要： A fluid from a fermentation process or the like is passed or circulated through chambers of a bipolar membrane electrodialysis unit to separate an ionizable organic acid stream and at least one co-ion or residual stream. The organic acid stream is preferably concentrated (e.g., by recirculation, dewatering or both), and a product is recovered from the concentrated stream, for example by crystallization, and other outputs from the electrodialysis unit may be integrated with overall treatment and applied elsewhere in the treatment system. Depleted feed may be returned upstream to enhance yield, condition the medium or form a by-product. Treatment systems of the invention may replace a cation exchange bed and/or various filter arrangements, and recirculation of the feed and product flows through the unit enhance recovery, separation and quality of the target species. An ED chamber may include a filling of ion exchange beads to maintain a desired operating efficiency as the feed is depleted, and the straightthrough operation effectively operates as pre-filtration stage to provide downstream product-bearing flows with processing characteristics for enhanced treatment, recovery and product quality. When operated to treat a downstream waste, systems allow additional recovery of value in the form of product, unexpended nutrients, co-factors and/or other components present in the waste.

摘要： A sheet having anion exchange functionality and a sheet having cation exchange functionality are juxtaposed and joined by current bonding into a unitary bipolar membrane. This may be done without added reactants or bonding agents by placing the two-layer assembly between opposed electrodes in a fluid cell, preferably at pressure, and applying power across the cell to split water in a junction region of the membrane assembly. Preferably the anion exchange sheet is treated with an iron salt solution so as to incorporate or immobilize the metal in the polymer during the current bonding process, and enhance operating characteristics of the bipolar junction. Membrane peel strength is comparable to or greater than that of an underlying sheet of ion exchange material, but the bonding is fully reversible, e.g., by soaking in a concentrated solution. Preferably both sheets include an aromatic backbone or cross-linker component. One membrane may be a self supporting membrane, such as a conventional electrodialysis exchange membrane of 5-50 mil (0.12-1.2 mm) thickness, while the other may also be a commercial membrane of opposite exchange type and of similar strength or thickness, or may be specially manufactured to tailor its performance in the completed membrane. For example, one or both starting sheets may be manufactured with a pore former or may otherwise have its porosity, cross-linking, strength, ion rejection characteristics or thickness tailored for more effective bipolar operation -for example, to enhance transport or diffusion, resist shear or mechanical forces, improve chemical resistance to splitting products or species in the intended feed, or the like. Preferably, prior to contacting and bonding, the anion exchange membrane is treated with a group VIII metal salt. The current-bonded unitary bilayer construction remains contact bonded over its surface and resists degradation in normal use.
摘要翻译：具有阴离子交换官能团的片材和具有阳离子交换功能的片材并置并通过电流接合连接成单一双极性膜。这可以通过将两层组件放置在流体池中的相对电极之间，优选地在压力下，并且跨过电池施加电力以在膜组件的接合区域中分离水来完成，而不需要添加反应物或粘合剂。优选地，用铁盐溶液处理阴离子交换片，以便在当前的接合过程中将金属掺入或固定在聚合物中，并增强双极结的操作特性。膜剥离强度与离子交换材料的下层片材的剥离强度相当或更大，但是粘合是完全可逆的，例如通过浸泡在浓缩溶液中。两片优选包括芳族主链或交联剂组分。一个膜可以是自支撑膜，例如5-50密耳（0.12-1.2mm）厚度的常规电渗析交换膜，而另一个膜也可以是具有相似交换类型和类似强度或厚度的商业膜，或可以特别制造以在完成的膜中调整其性能。例如，一个或两个起始片材可以用成孔剂制造，或者可以具有为更有效的双极操作而定制的孔隙率，交联，强度，离子排斥特性或厚度，例如增强转运或扩散，抗蚀剂剪切或机械力，提高对预期进料中的分解产物或物质的耐化学性等。优选地，在接触和接合之前，阴离子交换膜用VIII族金属盐处理。当前粘合的单层双层结构在其表面保持接触粘合，并在正常使用中抵抗降解。

摘要： A method for preventing osmotic blistering and other defects in the region of a flex line in a spirally-wound sheet filtration element includes applying an effective glue coating as a sealant to the feedstream side of a sheet in regions where a potential for blistering or layer damage exists, such as a fold line. The glue is applied to the inside of the fold, a spacer is positioned at the coated flex line, and the leaf is refolded and wound with other leaves to form a filter unit, such as a UF, NF or RO filter unit. The coating seals surface defects occurring during the fabrication process as well as the surrounding region, and the cured coating strengthens the region so blistering and delamination do not occur.

摘要： A process for treating produced water to generate high pressure steam. Produced water from heavy oil recovery operations is treated by first removi ng oil and grease. Feedwater is then acidified and steam stripped to remove alkalinity and dissolved non-condensable gases. Pretreated produced water is then fed t o an evaporator. Up to 95% or more of the pretreated produced water stream is evaporated to produce (1) a distillate having a trace amount of residual solutes therein, and (2) evaporator blowdown containing substantially all solutes fr om the produced water feed. The distillate may be directly used, or polished to remove the trace residual solutes before being fed to a steam generator. Steam generation in a packaged boiler, such as a water tube boiler having a steam drum and a mud drum with water cooled combustion chamber walls, produces 100% quality high pressure steam for down-hole use.

摘要： A process for conditioning of wastewater treatment brines for deep well injection during recovery of heavy hydrocarbon oils in situ. High pressure steam is used to mobilize oil, which is recovered in a mixture of oil and produced water. The produced water is pre-treated by removing residual oil. The remaining water is acidified and steam stripped to remove non-hydroxide alkalinity and non- condensable gases, and is then fed to a crystallizing evaporator, where it i s evaporated from a circulating brine slurry to produce (1) a distillate strea m having a trace amount of residual solutes, and (2) evaporator blowdown stream containing, as dissolved or suspended solids, substantially all of the solut es from the produced water feed. The distillate stream is used as boiler feedwater, either directly or after polishing. The evaporator blowdown is conditioned to remov e substantially all suspended solids and to produce a clear brine solution for deep well injection.

摘要： Solidification of water treatment wastewater brines from oil production operations. Concentrated wastewater brines from water treatment systems in heavy oil recovery operations are converted to solids suitable for landfill using Portland cement. The solidification process eliminates expensive drying equipment for wastewater brine solids, as well as the associated operation and maintenance of expensive dewatering equipment.
