By 2001, over 6,000 UV water treatment plants were operating in Europe. [62] Over time, UV costs have declined as researchers develop and use new UV methods to disinfect water and wastewater. Several countries have published regulations and guidance for the use of UV to disinfect drinking water supplies, including the US [63] [64] [65] and the ...
In wastewater treatment, a disinfection step with chlorine, ultra-violet (UV) radiation or ozonation can be included as tertiary treatment to remove pathogens from wastewater, for example if it is to be discharged to a river or the sea where there body contact immersion recreations is practiced (Europe) or reused to irrigate golf courses (US).
The primary solvent may be water or a hydrocarbon (historically, toxic solvents such as carbon tetrachloride and 1,1,1-Trichloroethane were used industrially, but have been phased out [9]). There are several formulations, dependent on the item being cleaned and the type of contamination (e.g., degreasing of metal, cleaning of printed circuit ...
Solar water disinfection, in short SODIS, is a type of portable water purification that uses solar energy to make biologically-contaminated (e.g. bacteria, viruses, protozoa and worms) water safe to drink. Water contaminated with non-biological agents such as toxic chemicals or heavy metals require additional steps to make the water safe to drink.
A toothbrush sanitizer is a device used to disinfect the tooth brush by applying short-wavelength ultraviolet (UV-C) light to kill or inactivate microorganisms. Studies in dental journals demonstrate that UV sanitizers effectively kill bacteria and microorganisms, but other forms of sanitizing, using common household products, were found to be equally or more successful at eliminating ...
