The accumulation, transport and processing of sewage results in the generation of off gases that must be controlled and treated. These organic gases vary in make-up and concentration. Within a large metropolitan wastewater treatment (sewer) system, the chemistry and concentration of these undesirable gases will also vary within the hours of a given day. The community and surrounding areas must be protected from the toxic gases and offensive odors that are generated. The packed tower is possibly the world’s most popular solution to this problem. Packed towers are also used to scrub acid gases and react with other undesirable emissions that come from a variety of industries.
The process that these structured scrubbers go through in order to remove contaminants from the contaminated gas stream is as follows: The gas stream passes through a packed structure with a large wetted surface area. The wetted area enables close contact between the gas and the scrubbing liquor, or scrubbing chemicals, which in turn allows the scrubbing liquor to react with the pollutants in the gas stream, removing them.
We have designed and built more than 100 packed tower scrubber systems, ranging in size from 1,000 to 67,000 CFM, and from single packed towers to facilities housing 38 packed towers arranged in parallel trains. These features allow for a larger rate of pollutant removal in less time.
In addition to the preferred packed tower scrubber system, Siemens supplies a wide range of odor control systems, which include:
- Biofiltration Systems
- Chemical Induction Systems
- Hybrid Odor Control Systems
- Vapor Odor Control Systems
- Degasifier/ Air Stripper Systems
