Abstract: A process using 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 gamma-type 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 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.

Abstract: Sewage water containing many pollutants including ammonia and phosphates is treated so that the ammonia and phosphates are preferentially removed through ion exchange while the other contaminants are allowed to remain in the water. Ferric hydroxide is deposited within the matrix of strong acid type cation exchange resin and the resin is rejuvenated with sodium hydroxide.

Abstract: An electro-deposition process for simultaneously producing manganese metal and manganese dioxide. Manganese metal and manganese dioxide are simultaneously electro-deposited in an electrolytic cell without the use of membranes separating the anode and cathode compartments. This is accomplished using a manganese chloride electrolyte in a temperature range of about 70 to 90 degrees C., with the free hydrochloride acid being removed from the electrolyte to a level below about 0.1M. The acid removal can be accomplished, for example, with an acid retardation step involving the use of strong base ion exchange resins in the preferred form. This is carried out in a continuous countercurrent current ion exchanger such that the molarity of the electrolyte is achieved with the acid being removed. The process described is suitable for the economical electro-deposition of manganese metal and manganese dioxide from leach solutions obtained from relatively low assay ores having of the order of 10 percent manganese. The current density and current efficiency are such that an economical process is achieved that is competitive with the processes of the prior art utilizing high grade ores.

Abstract: A process for the removal of thermally-stable contaminants from stack gas scrubbing amines using a continuous countercurrent ion exchange column. Amines contaminated after use in stack gas scrubbing are fed into the column containing an anion exchanger resin where the contaminants are sorbed on the resin. The amine is washed from the resin with hot water and is removed from the column. The resin is then pulsed to move the resin with the sorbed contaminants into a elution section of the column. The contaminants are removed using an eluant of sodium hydroxide solution, preferably containing chlorine to enhance elution of thiocyanate ion. A water wash removes traces of the hydroxide solution and any reaction products, and then the resin is again pulsed so as to be moved for reuse. The amines are regenerated with only the single type resin (preferably Type I) and with significantly reduced quantity of reagents.
