Kontaminace pitní vody arsenem a borem v Peru - původ, vlastnosti a řešení / Contamination of Peruvian drinking water by arsenic and boron - origin, properties and treatment

Excessive arsenic and boron concentrations determined in natural waters within the Department of Tacna in southern Peru are associated with active Andean volcanism, being further exacerbated by the ongoing mining activity in the area. Both arsenic and boron concentrations at five investigated sites significantly exceed the maximum permissible limits determined by the World Health Organisation and the Peruvian legislation for drinking water, thus affecting the health and wellbeing of the local population. Due to the remoteness of the area of interest, which lacks infrastructure, skilled human resources as well as capital, Photon Water Technology s.r.o. has come up with a solution based on the use of small water treatment plants operating on the principle of reverse osmosis in combination with a commercial remediation product Katalox Light® . This product enables the formation of alkaline conditions needed for proper complexation of boron into B(OH)4 - (aq), which is better remediated by the proposed technology. Reverse osmosis can remediate arsenic, although the efficiency of As removal depends on the chemical composition of natural waters at the investigated sites. Laboratory experiments have been focused to prove the viability of Katalox Light® for enhancing the rate of boron removal within the designed...
