REDUCTION OF INVESTMENT COSTS
Technology ART SAND’s kinetics is at least 10x faster compared to GAU, lowering the investments.
Micropollutants in surface and underground water are in relatively low concentrations (ng/l to µg/l). However, there are still dozens of different types, and therefore their overall concentration cannot be ignored. The problem with micropollutants in water is called the cocktail effect. This dangerous phenomenon forms when an otherwise harmless substance combines with one or more different substances. (more info) Considering the fact water contains dozens of substances, the possibility of the cocktail effect is high. There is a limited amount of information about the long-term effects of micropollutant on human health. Hygienic standards are set for the amounts of micropollutants in water, however they are based on prevention rather than scientific research.
MICROBIAL AND VIRAL DESINFECTION
ART SAND eliminates microbial and viral water contamination without chemicals. Its disinfection effects use the purely physically-mechanical force of carbon nanotubes on cellular walls. Therefore, it is a material with passive antimicrobial and antiviral effects immune to surface microorganism growth and is not prone to biofouling like GAU. ART SAND is suitable for further cleaning of drinking water and microbial water disinfection before final chlorination and spreading into the distribution networks.
CHLORINATION BY-PRODUCT ELIMINATION
Chlorination is the most common method for drinking water disinfection in the water treatment process. However, it comes with the disadvantage of creating chlorinated organic substances. They are formed during chlorination process of water which contains micropollutants but also common rganic particles. The most known are trihalomethanes having proven negative health impacts. (more info).
Chlorine is advantageous as it provides microbial water safety even during the time of water transfer through the distribution network to the final consumer. Therefore, this method will continue to be used.
After implementing the ART SAND technology after the last water chlorination step, it is possible to eliminate all the organic substances, and therefore avoid or decrease the number of dangerous trihalomethanes and still deliver microbially safe water to the consumer.
