Study to evaluate the effectiveness of deodorant product KMHS22 in training and camping conditions of soldiers
Abstract
The study was conducted to evaluate the effectiveness of the deodorant product KMHS22 on the odorous gases H2S, NH3 in feces in training and camping conditions for soldiers in 2 seasoning temperature ranges (hot and cold seasons). The experiments were carried out in outdoor conditions (in the forest and in the bunker fortifications) with the temperature in the hot season (in May and June) and in the cold season (in November). The results showed that the KMHS22 preparation was effective in reducing the 2 odorous emissions in the sanitary waste. The average amounts of H2S, NH3 gases in the waste samples using 100 g of the preparation /sample remaining after 168 h were < 10 µg/m3 and < 100 µg/m3, which are below the allowable level for toxic gas according to QCVN 05: 2023/BTNMT. The removal efficiencies of H2S, NH3 gas of the preparation in the 2 seasoning conditions were in the range of 71% - 90% and 73,8%-91,6% respectively, compared to those of the control waste without using the preparation. KMHS22 product meets the purpose of controlling the amount of toxic and odorous gas in fortifications and underground tunnels for military training activities as well as ensuring environmental hygiene in outdoor conditions.
