Abstract

This study evaluates reactive species generation in two transient spark plasma reactors producing plasma-activated water from deionized water, tap water, and simulated wastewater. Plasma was applied above the liquid surface using a high-voltage source, and physicochemical changes were monitored during treatment and over two weeks post-treatment. Reactive species (nitrate, nitrite, ammonium, ozone, and hydrogen peroxide) were quantified, and tetracycline and Enterococcus faecalis were targeted. Complete pollutant removal was achieved in the 200 mL reactor across all water matrices, whereas the 1000 mL reactor required longer treatment times and exhibited reduced efficiency with wastewater. In the 200 mL reactor, energy efficiency per order was higher; ozone and hydrogen peroxide reached up to 1.5 ppm and 8 ppm, respectively; nitrate stabilized after 15 min, nitrite showed transient behavior, and ammonium increased continuously. The larger reactor exhibited similar but slower trends. Over two weeks, in both reactors, nitrate and ammonium remained stable, while ozone and hydrogen peroxide decayed rapidly. Plasma exposure caused an initial pH drop and an increase in conductivity, which subsequently stabilized. These findings underscore the critical role of reactor volume and water composition in PAW chemistry, pollutant removal, and reactive species stability, confirming plasma treatment as a sustainable, by-product-free technology for water remediation.

Impact and social visibility

From the perspective of influence or social adoption, and based on metrics associated with mentions and interactions provided by agencies specializing in calculating the so-called "Alternative or Social Metrics," we can highlight as of 2026-04-24:

  • The use of this contribution in bookmarks, code forks, additions to favorite lists for recurrent reading, as well as general views, indicates that someone is using the publication as a basis for their current work. This may be a notable indicator of future more formal and academic citations. This claim is supported by the result of the "Capture" indicator, which yields a total of: 7 (PlumX).

With a more dissemination-oriented intent and targeting more general audiences, we can observe other more global scores such as:

    It is essential to present evidence supporting full alignment with institutional principles and guidelines on Open Science and the Conservation and Dissemination of Intellectual Heritage. A clear example of this is:

    • The work has been submitted to a journal whose editorial policy allows open Open Access publication.
    • Assignment of a Handle/URN as an identifier within the deposit in the Institutional Repository: https://oa.upm.es/95393/

    As a result of the publication of the work in the institutional repository, statistical usage data has been obtained that reflects its impact. In terms of dissemination, we can state that, as of
