Wastewater engineers can:
- Eliminate odor complaints
- Achieve results cost-effectively
- Use products that are non-toxic and environmentally friendly
Wastewater Odor Control
Municipalities and water districts today are extremely sensitive to odor complaints from the local community. Complaints of “sewer gas” odors are generally associated with the foul smelling hydrogen sulfide gas produced by bacteria using the sulfate ion, a common component of wastewater, as an oxygen source in the decomposition process.
This formation of aqueous hydrogen sulfide is commonly referred to as dissolved sulfide. Some of the dissolved sulfides then leave the aqueous phase to form gaseous hydrogen sulfide (H2S). The quantity of dissolved sulfides that are released into the gaseous phase depends primarily on the turbulence of the wastewater flow, which generally increases as the wastewater is discharged from a force main into a gravity flow line. This gas becomes a serious odor problem at the next downstream manhole where it can escape into the surrounding community. It is common to measure H2S levels in these manholes in excess of 30 parts per million (ppm), and occasionally exceeding 100-200 ppm.
In concentrations as low as 10 ppm, the gas can cause nausea and headaches. At more than 100 ppm, the H2S gas can cause eye injury, conjunctivitis, respiratory tract irritation and loss of smell.
Clearly, it is important to humans to have the formation of this gas minimized.
BioMagic’s products are extremely effective in dramatically reducing overall hydrogen sulfide levels in collections systems. They are non-toxic, environmentally friendly, require no special handling or storage and are extremely cost-effective.
Cost savings of up to 50% on product alone have been achieved, since less product is needed to achieve the desired result. Re-filling of storage containers is reduced as are transportation and handling costs.
