Municipalities and water districts today are IMG_Industry_Odour.png
extremely sensitive to odor complaints from the local  
community. Complaints of “sewer gas” odors are    
generally associated with the foul smelling hydrogen  
sulphide gas produced by bacteria using the
sulphate ion, a common component of wastewater,
as an oxygen source in the decomposition process.         

This formation of aqueous hydrogen sulphide is commonly referred to as dissolved
sulfide. Some of the dissolved sulphides then leave the aqueous phase to form gaseous hydrogen sulphide (H2S). The quantity of dissolved sulphides 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.

ENSOL 5000 is extremely effective in dramatically reducing overall hydrogen sulphide
levels in collection systems. It is non-toxic, environmentally friendly, requires no special handling or storage and is 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.
