The federal research project, PAkmem, deals with the recycling of industrial wastewater. The aim of the project is to develop and pilot an innovative integrative process for produced water treatment in the oil and gas industry utilizing flotation and ceramic micro-nano-membrane filtrations (MF-NF membranes) as well as the wastewater treatment of the ceramic industry with ceramic NF-membranes and electrodialysis (ED). The process utilized should remove fine particles, organic matter and divalent ions in order to make the water dischargeable or reusable (direct disposal or reuse as process water in the ceramic industry and the enhanced oil recovery reinjection in the oil and gas industry in which the water is conditioned in order to increase the oil production yield). Three pilot plants were designed and built according to strict safety standards and were operated on industrial manufacturing sites in Germany in 2019. Two innovative optical fine particle measuring techniques (inline and online) have been specially adapted for the project and integrated into the pilot plants. The results show promising technical potential for the use of ceramic membranes in the above-mentioned applications.

联邦研究项目PAkmem致力于工业废水的回收利用。该项目的目的是开发和试行一种创新的集成工艺，用于利用浮选和陶瓷微纳膜过滤（MF-NF膜）以及陶瓷工业废水处理的油气工业生产水处理陶瓷NF膜和电渗析（ED）。所使用的工艺应去除细颗粒，有机物和二价离子，以使水可排放或可重复使用（在陶瓷工业中直接作为工艺用水处理或再利用，以及在油气工业中提高回采率的油气工业中的回注）进行调节以增加石油产量）。根据严格的安全标准设计和建造了三个试点工厂，并于2019年在德国的工业生产基地进行了运营。针对该项目专门采用了两种创新的光学细颗粒测量技术（在线和在线），并已集成到试点工厂中。结果显示出在上述应用中使用陶瓷膜的有希望的技术潜力。
