摘要： An electrolytic process is used to reduce the silver content of fixer solution to a level such that it can be discharged as effluent. In the process silver is removed from aqueous fixer solutions by circulating the solution in a closed cycle through an electrolytic cell such that the residence time in the cell is not greater than one minute for each passage. The electrode loading is within the range between 5 and 15 mA/cm.sup.2 initially but is reduced in at least one further chronologically consecutive stage. Exhausted developer solution may be added to the fixer solution to act as a pH controlling redox system.

摘要： Process for the continuous separation of oil-in-water emulsions, which may contain surfactants, for example oil- and surfactant-containing effluents, by electrolysis, which comprises electrolysing such emulsions at a pH value of 5 to 10 and under a potential difference of at least 1.5 volts between the electrodes, optionally in the presence of a coagulating agent, with the formation of discrete oil particles, floating these oil particles with the aid of hydrogen gas formed simultaneously at the cathode, and then separating off the oily phase thus formed which is optionally condensed by the addition of flocculating agents.
摘要翻译：用于通过电解连续分离含水表面活性剂例如含油和表面活性剂的流出物的水包油乳液的方法，其包括在pH值为5至10的电解下将该乳液电解并在电极之间至少1.5伏，任选地在存在凝结剂的情况下，形成离散的油颗粒，借助于在阴极同时形成的氢气漂浮这些油颗粒，然后将这样形成的油相分离出来其任选地通过加入絮凝剂而缩合。

摘要： A device for sampling fluid is provided which comprises a plurality of sample vessels uniformly spaced apart in a circle and means for the alternate feeding of fluid into the individual sample vessels. A buffer vessel whose volume is at least three to five times greater than that of each individual sample vessel is connected upstream in series to the sample vessels. The sample vessels are U-shaped and have two substantially upright tubular arms which are joined together at their bottom ends. One arm is smaller in diameter and ends below the opening of the other arm or has a mouth or opening below the opening of the other arm. The means for feeding the fluid enter the thicker and higher arm of the sample vessels and are so built as to be able to empty the entire contents of the buffer vessel in the course of at most one to two minutes into the sample vessel.
摘要翻译：提供了一种用于采样流体的装置，其包括以圆形均匀间隔开的多个样品容器和用于将流体交替地供给到各个样品容器中的装置。体积比每个样品容器的体积至少高三至五倍的缓冲容器与样品容器串联连接上游。样品容器是U形的并且具有两个基本上直立的管状臂，它们在其底端处连接在一起。一只手臂的直径较小，并且在另一只手臂的开口下方终止，或者在另一臂的开口下方有一个口或开口。用于供给流体的装置进入样品容器的较厚和较高的臂，并且被构造成能够在至多一到两分钟的时间内将整个缓冲容器的内容物排空到样品容器中。
