A mobile processing system is disclosed for the removal of radioactive contaminants from nuclear process wastewater. The system is fully scalable, modular, and portable allowing the system to be fully customizable according to site-specific remediation requirements. It is designed to be both transported and operated from standard sized intermodal containers or custom designed enclosures for increased mobility between sites and on-site, further increasing the speed and ease with which the system may be deployed. Additionally, the system is completely modular wherein the various modules perform different forms or stages of wastewater remediation and may be connected in parallel and/or in series. Depending on the needs of the site, one or more different processes may be used. In some embodiments, one or more of the same modules may be used in the same operation.

Mobile processing system for hazardous and radioactive isotope removal

A regenerable inorganic media capable of removing contaminants by catalytic oxidation or reduction, as well as heavy metal adsorption, from well and surface water sources. The specific material is specially-treated microporous battery grade gamma-form electrolytic manganese dioxide, the treatment involving comminuting to a 20-60 mesh size, complete neutralization and washing to remove fines, residual acidity and neutralization products. Certain taste, odor and staining water contaminants such as hydrogen sulfide, iron and manganese can be oxidized and filtered by the media with subsequent removal from the system by simply backwashing with water or water in combination with simple chemicals. Heavy metals are removed by a different adsorption mechanism on the same media followed by regeneration with a dilute acid. Pretreatment of the media with sodium hydrosulfite further allows the removal of residual chlorine. This product demonstrates as high degree of selectivity and a high capacity for all three types of contaminants. The inorganic catalytic oxidizing/reducing and adsorbent material can be placed in larger canisters for point of entry use or in smaller cartridges for point of use applications, depending upon the particular requirement.

This product demonstrates a high degree of selectivity and a high capacity for all three types of contaminants. The results of the treatment of water solutions containing a wide variety of contaminants are given showing that most of the contaminants are readily removed to levels established by the U.S. Environmental Protection Agency for drinking water. The inorganic catalytic oxidizing/reducing and adsorbent material can be placed in larger canisters for point of entry use or in smaller cartridges for point of use applications, depending upon the particular requirement.
