Based on controlled-release of biocide, this hydrogel technology converts hydrogen sulfide and ammonia gases in air into harmless and odorless products, which aims to address the malodor problem at the source by killing odor causing microbes and inhibiting odor generation and converting malodors through catalytic transformation.
Malodor is an important class of air pollution that has a serious threat to personal health and quality of life. Sewer is one of major sources of malodor in urban environment and is particularly difficult to be treated.
