AI Technical Summary
Existing disinfection modules using activated carbon and UV light face issues with chemical interference and low disinfection efficacy, necessitating improved methods for enhanced disinfection and chemical removal.
Incorporation of silver traces into aqueous systems through colloidal dispersions of metallic silver on a fiber carrier, combined with short-wavelength UV irradiation, leveraging silver's oligodynamic properties for enhanced disinfection.
The solution achieves effective disinfection by complementing UV light with silver cations, overcoming chemical interference and improving disinfection performance.
Abstract
Description
Disinfection modules are usually modules which achieve the cleaning performance by filtration over activated carbon and irradiation with UV light.The construction described above therefore regularly has the following disadvantages: 1. the activated carbon tends to remove any disinfectant present, such as chlorine. 2. the irradiation with normal UVA or UVB light achieves only a low disinfection performance.This problem is solved by the features set out in claim 1.The invention achieves that the desired removal of the chemicals is not covered by the catalytic effect of the activated carbon.The invention specified in claim 2 is based on the problem that a disinfecting effect of silver cations is complementary to disinfection with UV light.This problem is solved by the features set out in claim 2.The invention achieves the effect that silver traces are introduced into aqueous systems during silvering with the aim of utilizing the oligodynamic properties of silver for disinfection and preservation, in the most common case for disinfecting drinking water. For this purpose, either colloidal dispersions of metallic silver are applied with a fiber as carrier substances. Silvering can be used not only for drinking water sterilisation, but certain pathogenic germs such as staphylococci are resistant to silver ions but also for algaecidal treatment.The invention specified in claim 3 is based on the problem of achieving a general disinfection of the water beyond the effect of silver.This problem is solved by the features set out in claim 3.The invention achieves that the water is irradiated with a short wavelength.
