  1. NATIONAL ACADEMY OF SCIENCES OF BELARUS INSTITUTE OF PHYSICAL ORGANIC CHEMISTRY MATERIAL AND EQUIPMENT FOR WATER PURIFICATIONFROM LEAD G.V. Medyak, V.I. Sokolova, A.A. Shunkevich, A.V. Bildyukevich*, V.P. Sokol, A.P. Polikarpov

  2. PROBLEM: The pollution of water resources by lead compounds is a serious ecological problem, especially in industrially developed regions. Commonly, the level of total lead content in atmospheric precipitations usually ranges from 1 to 50 μg/l, but in areas with intensive industry can reach up to 1 000 μg /l. Increasing of lead concentration in underground water is causing serious problems concerning drinking water supply in some locations in Middle Asia. Exceeding of the MPC of lead in drinking water (10 μg/l ) in Canada, Europe and some regions of Russian Federation is fixed

  3. CHEMICALY ACTIVE TEXTILE MATERIALS ADVANTAGES: • high speed of ion exchange, sorption and catalytic processes • possibility to usethin (2-6 cm) filtering layers • high flow rate • highchemical resistance and osmotic stability • possibility of multiple regenerations Comparison of the ordinary granular and fibrous ion exchangers • APPLICATIONS: • AIR PURIFICATION FROM TOXIC IMPURITIES IN INDUSTRY AND AGRICULTURE • SUPERFINE AIR PURIFICATION IN ELECTRONICS • INDIVIDUAL PROTECTIVE MEANS FOR HUMANS SKIN AND LUNGS • WATER PURIFICATION FROM HEAVY METALS, NITRATES, ARSENIC, ACIDS • DRINKING WATER PRODUCTION

  4. THE AIM OF THE RESEARCH IS TO OFFER THE TECHNOLOGY AND INSTALLATIONS FOR FINE PURIFICATION OF DRINKING WATER FROM LEAD THE NEW APPROACH FOR FINE PURIFICATION OF DRINKING WATER FROM LEAD IS OFFERED. IT CONSISTS IN APPLICATION OF FIBROUS CATION EXCHANGER FIBAN X-1 CHARACTERISTICS OF THE ION EXCHANGERS USED IN THIS WORK Cartridges made from FIBAN X-1 yarn

  5. Breakthrough curves for FIBAN X-1(A) and ANKB-35 (B) ion exchangers. 1 - Co2+, 2 - Ni2+, 3 - Zn2+, 4 - Cd2+, 5 - Cu2+, 6 - Pb2+ C/C0 C/C0 A B BV10-3 BV10-3 Model solution: 410-5 eq/l of Cu2+, Ni2+, Co2+, Zn2+, Cd2+, Pb2+ on the background of 4 10-3 eq/l of Ca2+. Filtration rate is 9.5 cm/min (190 BV/h); pH = 6;

  6. DYNAMIC CAPACITIES UP TO BREAKTHROUGH (CME = 0.05 MG/L) AND FULL DYNAMIC CAPACITIES OF ION EXCHANGERS ACCORDING TO HEAVY METAL IONS

  7. PURIFICATION OF WATER FROM LEAD USING10 CARTRIDGE MADE FROM FIBAN X-1 YARN COMPOSITION OF FEED WATER RESULTS OF WATER PURIFICATION AT DIFFERENT FLOW RATES

  8. PURIFICATION OF WATER FROM LEAD USING10 CARTRIDGE MADE FROM FIBAN X-1 YARN BREAKTHROUGH CURVE OF LEAD IONS AT FLOW RATE 1000 ± 50 ltr/h CPb, μg/l V, m3 Concentration of Pb in feed - 60 μg/l

  9. Based on the results of this study one- and multicartridge filters for water purification from lead were designed. Filters include either disposable ones for domestic application or industrial installations with automatic regeneration with productivity up to 200 m3/h. INDUSTRIAL CARTRIDGE FILTER

  10. WATER PURIFICATION PLANT WITH PRODUCTIVITY 40 m3/h

  11. OTHER APPLICATIONS OF FIBAN X-1 • drinking and domestic water purification from heavy metal ions • removing heavy metal ions: Fe(II), Cu(II), Ni(II), Co(II), Cd(II), Zn(II), Hg(II) -from the technological solutions • effective sorption of radionuclide Sr-90 • concentrating of the heavy and transition metals from diluted solutions for analysis • air purification from the vapor and aerosol impurities of the basic nature (ammonia, organic amines, hydrazine, oxides and metal hydroxides) • protection means of the respiratory organs • organic catalysis (by complex metal ions)
