    Chinese-German research funding for efficient wastewater after-treatment

    15.11.2019

    HOLINGER is participating in a Federal Ministry of Education and Research joint project called PEPcat. The aim of the project is the development of an energy- and resource-efficient process for the aftertreatment of water from wastewater treatment plants. The method is intended to allow reuse of the water while reducing the human and eco-toxicological potential.

     

    The process uses highly reactive hydroxyl radicals that are generated directly in the water and consumed within a short time, leaving no chemicals behind. Hydroxl radicals, that are even more reactive than, for example, chlorine can be generated using high-energy UV light in the presence of titanium dioxide as a catalyst. This process has already been well researched. In PEPcat, this principle is now to be combined with the so-called plasmonic effect, which enables the titanium dioxide to act as a catalyst even with visible light. Thanks to this innovative approach, sunlight can also be used for the process or its efficiency significantly increased if artificial radiation sources are used. The research results will be integrated into a local concept for wastewater reuse in China.
