Abstract
A TNB-99 coded regenerable filter cartridge contains complex additives for the removal of arsenic (As), and/or toxic heavy metal ions and/or radioactive isotope contaminants. The filter charge contains a given wt.% of minerals having general formula: MyAlOasteriskYNa2asterisk2SiO2asteriskVH2O (K-10 gamma-alumina); 1 AlO(H); pseudo-boehmite; and chinoptylolite mineral having a general formula: LxOasteriskAl2O3asteriskSiO2asterisk6H2O chosen from zeolite-type minerals of general formula: MxOasteriskAl2O3asteriskYSiO2ZH2O. Additive substances are regenerated, when a dilute, preferably 0.1M, solution of tartaric or citric acid, or a mixture of both is passed through these, followed by rinsing with water. The purified filter medium is optionally treated with an OH-ion supplying compound.
