The NXT-2 patented technology was developed in cooperation between EP Minerals and the University of Nevada-Reno, to provide cost-effective treatment for the removal of arsenic from drinking water to less than 10 ppb to meet U.S. Environmental Protection Agency requirements. NXT-2 is a free-flowing, lanthanum-based mixed metal oxy-hydroxide media that was designed to provide maximum capacity through high surface area. The high surface area of the media, which is often greater than 250 m2/gram, increases the media's capacity for arsenic adsorption and extends bed volumes.
Stability
In addition to the high surface area, NXT-2 is incredibly stable. Once the arsenic is bound to the media, NXT-2 will not release the bound arsenic in the event of pH upset. NXT-2 has a high zeta point pH of 9.5, while many iron based medias have a zeta point of 7.8 pH. This stability reduces the potential to distribute water which has high arsenic concentrations due to loss of pH control.
Cost Effective
NXT-2's high capacity for arsenic (As) adsorption provides users with the lowest treatment cost per thousand gallons. The particle size and high surface area allow for a higher life and greater bed volumes (BV) before breakthrough.
In addition to arsenic, NXT-2 is effective for treatment of other contaminants including phosphate, chromium, selenium, fluoride, antimony, lead to name a few.
Safe
NXT-2 will not release bound arsenic in the event of pH upset reducing the potential that contaminated water will reach distribution. NXT-2 has been certified by NSF and meets TCLP requirements.
