20140306148 | Particulate Sorption Medium Prepared From Partially Decomposed Organic Matter - A process for the preparation from a partially decomposed organic material like peat a granulated or pelletized sorption medium using low-temperature, thermal activation of the sorption medium to produce a high degree of granule or pellet hardness balanced against an efficacious level of ion-exchange and adsorption capacity, followed by chemical treatment of the thermally-activated sorption material via an acid solution and a salt solution to increase its ion-exchange and adsorption performance while minimizing the transfer of natural impurities found in the sorption medium to an aqueous solution is provided by this invention. The sorption medium of this invention can be used in a variety of aqueous solution treatment processes, such as wastewater treatment. | 10-16-2014 |
20120267569 | PRODUCTION OF MULTIFUNCTIONAL GRANULAR MEDIUM BY PARTIAL ACTIVATION OF PARTIALLY DECOMPOSED ORGANIC MATTER - A process for the production of low-temperature activated or partially activated partially decomposed organic matter for use as an ion-exchange medium comprising the steps of granulating partially decomposed moisture-bearing organic matter, drying the granules and activating the granules at a temperature of about 175-520° C., wherein the granule has a hardness and cation-exchange capacity suitable for a particular application desired. | 10-25-2012 |
