drinking water arsenic Applications
Compliance with the USEPA’s new maximum contaminant level (MCL) of 10 parts per billion (ppb) for arsenic affects thousands of small public water systems in the U.S. Among treatment options available, few are simple, proven, affordable, and reliable. AdEdge offers a line of packaged, pre-engineered drinking water treatment systems which are ideal for small public water systems such as schools, mobile home parks, shopping centers, subdivisions, and more.

Nitrogen is a nutrient essential to all forms of life as a basic building block of plant and animal protein. Nevertheless, too much of it can be toxic. The processes used for the removal of ammonium ions from drinking waters include ion exchange. PuriTech`s ION-IX system can be broken up into 4 distinctive zones with each zone operating continuously. The resin is initially loaded with the Ammonia ions (and partially calcium and magnesium)in the adsorption zone. As the ION-IX multi-port valve rotates, the resin that has been saturated with Ammonia ions (and some calcium and magnesium ions)moves into a one-bed displacement zone with softened water to ensure hard water does not cause precipitation within the multi port valve.

All described properties of Fe(0) nanoparticles can be even used for decomposition of pollutants contained in the waste water, mainly for treatment of industrial sewage and hutch water. The usage of nanoiron can represent a significant qualitative step in the classical technologies of water treatment including drinking water. The extremely reactive iron nanoparticles thus offer a possibility to solve long-lasting problems with a high content of uranium and arsenic in a variety of localities in the Central Europe. They can be also used for a reduction of the content of heavy metals, nitrates and phosphates in the drinking water. Just these inorganic pollutants, which are hardly or expensively removed by standard technologies, are effectively removed by Fe(0) nanoparticles.
