On the base of fibrous ion exchangers, indicator materials were obtained for sorbates of an alkaline and acidic nature, intended to visualize the working time of the filter layer during ion exchange air purification. The optimal conditions for their production and operation were determined. The practical applicability for the manufacture of indicator cartridges for filters of deep air purification and personal protective equipment for human respiratory organs and skin with the aim of timely visualizing of the sorption resource depletion, due to the contrast and sensitivity of the color change, was demonstrated.

Infection control among patients is critical for diseases like COVID-19. The concentration of patients in a few facilities burdens healthcare providers and the healthcare system. This study examined the operations of an extended anteroom in a dedicated COVID-19 hospital. It presents issues to consider in the deployment and operation of an extended anteroom through discussions by expert working groups. The subjects covered included efficient space, staffing, equipment management, and education. The process involved wearing personal protective equipment (PPE; in this case, Level D), and if necessary, wearing additional powered air purification respirators (PAPR), after moving from the preparation room to the dressing room, and when entering the hospital through the entrance passage. When leaving the hospital, personnel used a mandatory exit-only passage; in the dressing room, they undressed, and then went outside, in this order. The efficient spatial composition of the anteroom facilitated entry and exit and the separation of contaminated areas and non-contaminated areas using colors and lines. It is necessary to develop operational guidelines for hospitals that treat infectious diseases and conduct research to improve care. The study indicated the need to develop educational programs and use educational simulations to address regionally spread infectious diseases

Cleaning Device

The present catalytic air purification device–air cleaning device is capable to reduce nitrogen oxide sand carbon monoxide concentrations in polluted air stream and to achieve high cleaning efficiency. The principle of operation of catalytic air cleaning device is based on plasma coating formed catalysts usage. At high temperatures and oxygen concentrations in the experimental device channel, catalysts become active and reactions of conversion of pollutants start. In this research, the efficiency of cleaning the air from nitrogen oxides and carbon monoxide, by using plasma coating formed titanium oxide and copper-chromium catalysts, is carried out. 50% propane – 50% butane gas mix was used to generate polluted air flow. The maximum cleaning efficiency, cleaning the air of nitrogen oxides and carbon monoxide, reached 86% and 77%, when the average flow rate of polluted air was 0.10 m/s, oxygen concentration in II section of device was 0.5–0.6% and in I section – 0.1–0.2%. Nagrinėjamas įrenginys – katalitinis oro valymo įrenginys, mažinantis azoto oksidų ir anglies monoksido koncentracijas užterštame oro sraute. Katalitinis oro valymo įrenginys veikia naudodamas plazminiu purškimu suformuotus katalizatorius. Esant aukštai temperatūrai ir optimaliai deguonies koncentracijai įrenginio eksperimentiniame kanale, katalizatorių paviršius tampa aktyvus, ir vyksta sudėtingos teršalų konversijos reakcijos. Atliktuose tyrimuose nagrinėtas suminis titano oksido ir vario-chromo oksido katalizatorių, kurie buvo pagaminti plazminio purškimo metodu, srauto, užteršto azoto oksidais ir anglies monoksidu, valymo efektyvumas. Užterštam oro srautui sugeneruoti buvo naudojamas 50 % propano – 50 % butano dujų mišinys. Didžiausias valymo efektyvumas, valant orą nuo azoto oksidų ir anglies monoksido, atitinkamai siekė 86 % ir 77 %, esant 0,10 m/s vidutiniam užteršto srauto greičiui, 0,5–0,6 % deguonies koncentracijai II-ojoje įrenginio sekcijoje ir 0,1–0,2 % deguonies koncentracijai I-ojoje įrenginio sekcijoje.
