Waste water treatment, is the process of removing contaminants from wastewater and household sewage. It includes physical, chemical, and biological processes to remove physical, chemical and biological contaminants.
Odors emitted by waste water treatment are typically an indication of an anaerobic conditions. Early stages of processing will tend to produce toxic gases, like Hydrogen Sulphide (H S), Sulphur Dioxide (SO), Bromine and Oxides of Nitrogen, Chlorine etc which can be even corrosive in higher concentrations, which makes odor removal a necessary criteria.
There is a growing demand for high-efficiency odor control systems at waste water treatment plants. In most water pumping stations, filtration plants, and waste water control plants, control of odor is of prime importance. Malodorous gases require gas phase filtration prior to exhausting from irrigation tanks and pumping stations. Therefore, control of hydrogen sulphide and noxious odors, which are detected by humans.
Chemical cleaning compounds, solid waste, and other accumulated human garbage increases the natural contamination of sewage water and thus ultimately leading to air contamination. Nuisance odors and gasses evade the best preventative efforts of modern waste water treatment plants. Industrial odor control is a complex and difficult task. Even as waste disposal workers are now beginning to understand the use of green alternatives for odor control, researchers are seeking solutions from even more areas of technology.
By using a Bry-Air EcoScrub, odor can be controlled through the process of Gas Phase Filtration. It is a desiccant based dry air scrubber. The desiccant is impregnated with required chemicals which react with the odour-causing gases and neutralize them. The cleaned air makes working conditions inside wastewater and sewage treatment plants conducive and living conditions in the neighborhood more comfortable.
