Enviro-Scrub® is a specialized product developed by Q2 Technologies for effective wastewater odor control. Specifically designed for the wastewater, landfill gas, digester gas, and pulp & paper industries, Enviro-Scrub® offers tailor-made formulations to address the challenges of hydrogen sulfide (H2S) and mercaptan removal. With a proven track record spanning over 25 years, our patented technology reacts into non-hazardous, biodegradable molecules, providing a safe and eco-friendly solution. The wastewater odor control industry demands reliable and efficient solutions to meet odor standards and reduce emissions. Q2 Technologies, drawing from its extensive experience in H2S and mercaptan removal across various industries, offers customized formulations that optimize processes while prioritizing environmental sustainability.


A wastewater collection system running through a suburban community had a strong hydrogen sulfide (H2S) odor causing neighbors’ complaints. The wastewater treatment plant tried different programs for odor control to address the complaints of the neighboring community. A ferrous sulfate treating program was tried unsuccessfully resulting in uninterrupted community complaints and high operational costs.

  • Reduce hydrogen sulfide odor causing complaints from community members.
  • A sulfate treating program had already been implemented and results were not succesful.
  • Q2 Technologies was given the opportunity to implement the Enviro-Scrub® program. This custom-made program added a tote of our custom formulated chemical with a metering pump feeding directly into the lift station, as seen on diagram 1. The Enviro-Scrub® was fed into the lift station influent ahead of the baffle station.

  • The neighboring community has not presented any further complaints. Labor costs have been reduced given that the Enviro-Scrub® program supplies the scavenging chemical with a metering pump on a continuous basis.


  • Eliminated odor complaints in neighborhood.
  • Enviro-Scrub® is more cost effective than ferrous sulfate and magnesium hydroxide.
