Experiencing Odors From a Long, Slow-Moving Force Main?

Treatment of sulfide within collection systems is a difficult proposition. Organisms responsible for the production of sulfide are found system-wide. They grow within a collection system at any point where oxygen is limited. Anaerobic or anoxic zones within a collection system create the perfect environment for the production of sulfide. Sulfide producing organisms harvest all oxygen molecules from oxygen rich sulfur compounds (e.g. sulfate, sulfite) commonly available in wastewater for use in their metabolic processes. The resulting sulfide production causes significant odor issues and tremendous corrosive damage to the infrastructure. Corrosion occurs as sulfide is converted to sulfuric acid by another class of organisms that use sulfide as an energy source.
So, what can be done? Consider SOURCE TECHNOLOGIES’…

What is ESP?

Like VSP, ESP is a CATALYZED OXYGENATION PROCESS in which a catalyst, Endurox, is added to oxygen (O2). SOURCE can offer several customized blends of ESP that are determined by detention time. We can usually use ESP to treat detention times of 8 to 60 hours! As with VSP, ESP can treat sulfide odors at the point of treatment (i.e wet well or manhole). However, that’s where the similarity ends. Beyond the initial 8 hours of treatment, ESP then provides a food source for the sulfide reducing bacteria (SRB) preventing the reduction of sulfate to sulfide for up to 60 hours.

SOURCE can fine tune the ESP to meet varying lengths of detention time.

  • ESP 11 works from 8 – 16 hours
  • ESP 21 works from 16 – 20 hours
  • ESP 31 works from 20 – 26 hours
  • ESP 41 works from 26 – 60 hours

Like VSP, application of ESP is very straightforward. The process simply requires metering of the selected ESP blend with oxygen into the targeted system.
