Odor control / hydrogen sulfide prevention represents one of the biggest problems facing the wastewater industry today. Aulick Chemical Solutions has combined the chemistry of H2S encapsulation and prevention creating an improved and more effective Nitra-Nox.
Nitra-Nox is a naturally proven solution used to prevent the production of H2S in wastewater. H2S is produced when the anaerobic bacteria feeds on sulfates. Nitra-Nox is an alternative oxygen source, preventing future production of H2S. With our latest encapsulation technology, Nitra-Nox can also be fed where H2S is already present. Nitra-Nox will encapsulate the H2S and prevent it from being expressed and enable future production to be prevented.
It's not one size fits all when it comes to odor control. First, the odor must be identified. Second, the location of the odor, location where odor is produced and concentration of the odor must be determined.
In this situation the H2S odor issues are at manholes receiving all flow prior to the wastewater treatment plant and at the air release valve on the forcemain at Wolf Creek Pump Station. To alleviate the odors, Aulick Chemical Solutions evaluated the entire collection system.
For the H2S issue at the manhole prior to the wastewater treatment plant, the entire system was tested for H2S.
For the odor issue at the release valve, the H2S level was measured at the Wolf Run Pump Station. The 0 ppm reading indicates a perfect location to feed Nitra-Nox and inhibit the production of H2S in the forcemain.
|Wolf Creek Pump Station:||6.5 ppm|
|Marble Falls Pump Station:||2 ppm|
|Buffalo Ridge Pump Station:||10 ppm|
|Northside Pump Station:||0 ppm|
The H2S coming from Wolf Run Pump Station will be inhibited by feeding at the station. The H2S coming from the Buffalo Ridge Pump Station will also have to be treated at the Buffalo Ridge Pump Station. The H2S coming from Marble Falls Pump Station is further evaluated and is determined that the majority of the H2S is coming from the gravity flowing into the Marble Falls Pump Station. Feeding Nitra-Nox at the Estes Park Manhole will inhibit the H2S at Marble Falls Pump Station and the discharge into the main manhole prior to the wastewater treatment plant.
Nitra-Nox is available in 55-gallon drums, 330 gallon totes and bulk truckloads of 3000 gallons or more.
