POROUS BLOCK FILTER MATERIAL FOR PURIFYING DRINKING WATER FROM IRON AND A METHOD FOR PRODUCTION THEREOF

FIELD: technological processes.SUBSTANCE: invention relates to porous block filtration material for purification of drinking water from iron, containing fine particles of activated carbon with particle size of 0.15-0.3 mm, specific filtration surface from 800 m/g, iodine number from 800 mg/g and static exchange capacity by copper from 0.7 mg-eq/g, and polymer binder in following ratio of components, wt%: activated carbon 80-90, polymer binder 10-20, with pore size 50-100 mcm. Filter material is obtained by extrusion or hot pressing of mixture of powdered material with particle size of 0.15-0.3 mm from activated carbon with specific filtration surface area of 900 m/g, iodine number from 900 mg/g, static copper exchange capacity from 0.8 mg-eq/g, with water content of 8-12 % and polymer binder, and the process is carried out at a compression ratio of mixture of 15-20 % and temperature of 10-40 °C is higher than softening point of polymer binder at ratio of activated carbon: polymer binder of 80-90:10-20 wt%. Porous block material is made in the form of plates or hollow bodies of various shapes. Polymer binder contains polymers from classes of polyolefins and/or polyesters and/or copolymers thereof with a melt index of 2-20 g/10 min according to ASTM D 1238 at 190 °C and load 25 kg. Porous block material is intended for use as part of pressure and gravity filter cartridges for purification of drinking water from iron and other contaminants.EFFECT: providing high-efficiency purification of drinking water - at level of 90-99 % of iron during a considerable consumer resource, efficient additional purification of water from chlorine present in water, organochlorine compounds, heavy metals, for example, lead, copper, and other contaminants due to developed adsorption surface.5 cl, 1 dwg, 4 ex, 1 tbl Изобретение относится к пористому блочному фильтрующему материалу для очистки питьевой воды от железа, содержащему мелкодисперсные частицы активированного угля с размером частиц 0,15-0,3 мм, удельной поверхностью фильтрации от 800 м/г, йодным числом от 800 мг/г и статической обменной емкостью по меди от 0,7 мг-экв/г, и полимерное связующее при следующем соотношении компонентов, мас. %: активированный уголь 80-90, полимерное связующее 10-20, с размером пор 50-100 мкм.
