FIELD: water treatment. ^ SUBSTANCE: sorbent catalyst appropriate to produce drinking water contains, as carrier, filter material (ODM-2F), ground opokas with summary pore volume 0.45-0.55 cm3/g (98.0-99.5%) and manganese dioxide (0.5-2.0%). Sorption capacity of sorbent catalyst exceeds that of quartz sand-based "black sand" by a factor above 1.5. ^ EFFECT: increased sorption capacity. ^ 1 tbl, 4 ex |
