Sewage Treatment

Urban sewage features complex sources and components and releases strongly irritating odors during treatment. The main pollutants include sulfur-containing compounds such as hydrogen sulfide, sulfur dioxide, mercaptans and thiophenes; nitrogen-containing compounds such as ammonia and amines; hydrocarbons including alkanes, alkenes and aromatic hydrocarbons; and oxygenated compounds such as alcohols and aldehydes. Among these volatile gases, hydrogen sulfide dominates concentration and causes severe malodor and air pollution.

These odorous gases not only pose poisoning risks to on-site and surrounding personnel, but also invade automatic control rooms in sewage treatment plants, causing severe corrosion of electronic and electrical equipment, shortening equipment service life and threatening the stable operation of automation systems.

EcoKeeper targets zero-odor environments. Adopting physical adsorption, chemical adsorption and catalytic purification processes, equipped with diversified functional materials and filter modules, it comprehensively eliminates all types of peculiar smells and malodors in sewage treatment scenarios.
