His ozonation process disinfestates ships'ballast waters of feral species to avoid introduction into coastal waters by shipping and has been applied on oil tankers.
22.
HAAs can be formed by chlorination, ozonation or chloramination of water with formation promoted by slightly acidic water, high organic matter content and elevated temperature.
23.
It's also now spending $ 15 million on an ozonation facility, which will be complete within two years and will provide state-of-the-art water cleanup.
24.
Disinfecting effect of Mixed oxidant is higher than other methods such as chlorination and in comparison to other methods such as ozonation and using ultraviolet ray, contains residual chlorine in the water.
25.
These include the use of technologies such as UV irradiation, ozonation, electrochlorination, hydrodynamic cavitation and ultrasound, among others, applied as stand-alone or combined treatments . and began approving in 2016.
26.
While quality control and quality assurance in such locations may be variable, sophisticated technology ( such as multi-stage particle filtration, UV irradiation, ozonation, and membrane filtration ) is applied with increasing frequency.
27.
The advanced treatment facilities use two-stage powdered activated carbon ( PAC ), addition of lime, two-stage recarbonation, sand filtration, ozonation, granular activated carbon ( GAC ), and chlorination for purifying the water.
28.
"' EBOO "'or "'Extracorporeal Blood Oxygenation and Ozonation "'is a hemofiltration-like procedure developed and reported in 2005 as being used in the medical department at the University of Siena in Italy.
29.
To enhance the quality of the marine discharge from the Davis WWTP, a number of different, proven technologies have been selected to be used in the future, such as ozonation, UV disinfection, chlorine, as well as UF, activated carbon filtration and RO.
30.
What generally makes bottled waters taste better than tap water is processing methods such as reverse osmosis ( in which the water is forced through a semi-permeable membrane ), distillation, filtration and / or ozonation ( application of ozone ) to remove chemical and microbiological contaminants, and the use of ultraviolet light rather than chlorine to disinfect.
