The Evergreen (EVG) Redox Process™

The EVG Redox Process™ is a next-generation approach to wastewater odor control that replaces traditional caustic and bleach with advanced, non-hazardous EVG chemistry. Designed for new and existing wet scrubbers, it delivers up to 99% odor control while reducing operating costs, corrosion, maintenance, and environmental risk.


EVG chemistry is added to the scrubber sumps and continuously recirculates, eliminating the need for chemical feed systems. Source provides full-service, installation, and ongoing support. The process converts H₂S into elemental sulfur, which can be efficiently filtered from the system. The result is clean, odor-free air that can be discharged without additional treatment.


With no caustic throughput, the EVG Redox Process minimizes corrosion and can help reduce both operating expenses and capital replacement costs. At the same time, it eliminates the hazards associated with traditional caustic and bleach handling-creating a safer environment for workers, neighbors, and the community.
