Disinfection and deodorization of textile floor coverings with plasma-activated water vapour during daily maintenance cleaning

IGF 20437 N

The aim of the research project is to develop a process for disinfecting and deodorising textile floor coverings on the basis of plasma-activated water vapour:
To this end, suitable process control, i.e. suitable plasma and process parameters, will be developed. Furthermore, a functional model of a DBE brush vacuum cleaner (DBE: dielectric barrier discharge) will be designed, which is equipped with an innovative plasma technology.

The main components are DBE nozzles and an evaporator for generating water vapour, combined with standard brush rollers. The plasma-activated water vapour generated is used to disinfect and deodorise the treated floor coverings. As before, dirt is removed by brush suction in a single operation.

The new process can be used for daily maintenance cleaning of textile floor coverings, i.e. for full-surface hygiene and dirt removal, as well as for stain removal or cleaning and disinfection of local, potentially infectious soiling.

The project results will provide the predominantly small and medium-sized cleaning service providers with a highly innovative cleaning process for disinfecting and deodorising textile floor coverings as part of daily maintenance cleaning.

Since only very small quantities of water are introduced into the textile floor coverings during disinfecting and deodorizing cleaning, these can be gently cleaned and immediately walked on again. Furthermore, no chemicals are required. By increasing their market shares, cleaning service providers can significantly improve their economic situation.
