DRINKING WATER




ART SAND technology brings in the field of drinking waters:

  • Eliminates pesticides, herbicides and fungicides from water
  • Eliminates drugs, personal care products and endocrine disruptors
  • Microbial and viral disinfection without the use of chemicals
  • Eliminates by-products of disinfection connected to chlorination or alternative disinfectants
  • Eliminates substances in water causing odor and color change
  • Eliminates toxins of algae and cyanobacteria
  • Significantly decreases investment costs in comparison with GAU

REDUCTION OF INVESTMENT COSTS

Technology ART SAND’s kinetics is at least 10x faster compared to GAU, lowering the investments.

COCKTAIL EFFECT

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.

AGROCHEMICALS

Nowadays, their use is strictly regulated. However, after dozens of years, we still find traces in surface and underground water flushed from surrounding agricultural fields.

DRUGS

From our analysis, we found the wastewater treatment plant, serving 1.000.000 citizens, releases an equivalent of 1000 tons of drugs into the Vltava river per year. According to this, every Prague citizen would consume 50 pills a year. This state of water contributes to antibiotics resistance (more info)

HORMONAL SUBSTANCES

Hormones enter water systems due to human consumption and animal products. Mainly, hormones in water cause harm to water fauna (more info). The effect on the human population is yet to be determined.

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.
