Manufactured by Epiphany Environmentalbased in USA
According to the OECD, the amount of water withdrawn from aquifers, lakes, rivers, and other sources will increase by 55% by 2050, due in large part to industrial water usage. Once that water is used, it is often contaminated with heavy metals, salts, sediments, and organic material. This water is routinely dumped into rivers and lakes, where it can go on to contaminate groundwater and make ...
-
Manufactured by Tusaar Corp.based in USA
Tusaar’s technology simply and efficiently sequesters contaminating metals from process or waste streams to enable water reuse, discharge or further treatment. It works in the presence of competing metals and organics. It’s also highly effective on numerous organo-metallic complexes. And even better, lab experiments have shown a very long active media life. Metals can be easily ...

based in GERMANY
Natural wetlands, permanently waterlogged areas populated by hydrophytic plants such as reeds, comprise a variety of sub-surface micro-habitats of differing oxygenation and redox potential, and support a diversity of microorganisms – bacteria, fungi, actinomycetes, protozoa – which degrade organic and inorganic substrates entering the system. Constructed wetland systems are ...
