Abstract

Important challenges in the global water situation, mainly resulting from worldwide population growth and climate change, require novel innovative water technologies in order to ensure a supply of drinking water and reduce global water pollution. Against this background, the adaptation of highly advanced nanotechnology to traditional process engineering offers new opportunities in technological developments for advanced water and wastewater technology processes. Here, an overview of recent advances in nanotechnologies for water and wastewater treatment processes is provided, including nanobased materials, such as nanoadsorbents, nanometals, nanomembranes, and photocatalysts. The beneficial properties of these materials as well as technical barriers when compared with conventional processes are reported. The state of commercialization is presented and an outlook on further research opportunities is given for each type of nanobased material and process. In addition to the promising technological enhancements, the limitations of nanotechnology for water applications, such as laws and regulations as well as potential health risks, are summarized. The legal framework according to nanoengineered materials and processes that are used for water and wastewater treatment is considered for European countries and for the USA.

纳米技术在水处理方面的创新。
全球水资源形势的重大挑战主要是由世界人口增长和气候变化引起的,需要新颖的创新水技术,以确保饮用水的供应并减少全球水污染。在这种背景下,将高度先进的纳米技术应用于传统的工艺工程为先进的水和废水技术工艺的技术发展提供了新的机会。本文概述了水和废水处理过程中纳米技术的最新进展,包括纳米材料,如纳米吸附剂、纳米金属、纳米膜和光催化剂。报道了这些材料的有利性能以及与传统工艺相比的技术障碍。介绍了商业化的现状,并对每种纳米基材料和工艺的进一步研究机会进行了展望。除了有希望的技术增强外,还总结了纳米技术在水应用方面的局限性,例如法律法规以及潜在的健康风险。根据用于水和废水处理的纳米工程材料和工艺的法律框架正在考虑适用于欧洲国家和美国。
