Patent granted for “Plasma Activated Water”

Our patent application for "Plasma Activated Water" was approved in Europe (EP3411085). The patent concerns the production of plasma-activated water for the disinfection of objects, in particular dentures and the treatment of teeth.

Chemical solutions are typically used to clean dentures, but they contain comparatively high concentrations of chemicals. The problem, however, is that these solutions are not suitable for consumption and are harmful if consumed by mistake – similar to toothpaste, which at best should not be swallowed.

Furthermore, for the bleaching of dentures and/or teeth, mostly concentrated hydrogen peroxide is used that is far above the EU limit for non-professional tooth bleaching. Here, plasma-activated water offers a safe, waste-free alternative. The patent protection gained, hence should strengthen terraplasma’s position in plasma technology even more.

terraplasma and TUM develop “CAPbot” prototype of a mobile cleaning robot with plasma-activated mist

As part of an interdisciplinary research project called “CAPbot”, terraplasma GmbH and the Chair of Medical Engineering Materials and Implants at the Technical University of Munich (TUM) are developing a new type of platform technology for ground-based disinfection. The aim is to integrate a cold plasma source into an automated wiping robot system for use in highly sensitive environments such as clinics, food processing, the pharmaceutical and cosmetics industries and public facilities.

terraplasma focuses on innovative water treatment with patented cold plasma technology

Garching / Munich, March 21st, 2025 – Tomorrow is World Water Day: The aim of this day of action, launched by UNESCO in 1993, is to draw attention to the importance of (clean) water as the most important basis of life for all of hu-manity. Water is a limited and increasingly scarce resource. Around 785 mil-lion people are already affected by acute water shortages. The availability and quality of water is currently changing dramatically due to population growth and climate change and is constantly becoming the greatest challenge for us humans. These are good reasons for terraplasma GmbH to focus more on the large field of water treatment and to continue its success story.

terraplasma is developing a demonstrator for water treatment with Cold Plasma on an industrial scale

A few months ago, the Cold Plasma pioneers at terraplasma GmbH were able to show that with their highly effective technology it is possible to reduce the so-called “forever chemicals” (PFAS Per- and polyFluorinated Alkyl Substances) in drinking water. As part of a research study funded by ESA Spark Funding (https://www.esa-technology-broker.it/spark-funding/), the company wants to expand its research and develop a water treatment system with a significantly more powerful flow rate. Under the project name “Plasma Pure Water”, ter-raplasma aims to complete a larger demonstration system that will meet the requirements of large households and smaller industrial applications with at least 100 liters per minute. A first prototype named “tpWater” is already being tested and optimized.
