Portfolio Categories: Mobile Water Treatment and Vapor Scrubbing.


On Christmas Eve 2019 the citizens of a Northern California city woke up to a terrible rotten egg smell. The General Manager of the water treatment facility made a call to Envent around 2:30 p.m. on December 24th, 2019. He said he had a terrible rotten egg smell coming out of one of the digesters. Envent’s engineering team quickly sprung into action.


The engineering team put together a solution which would mitigate the H2S coming out of the digester. Our technician went to the site and the H2S in the vapor stream venting to atmosphere was at 3,000 ppm. The Water Treatment plant is located in a centralized neighborhood of homes. You could smell the H2S for miles. The team mobilized an ESCRUB 2000-SS and two each 2,000 pound vapor media vessels containing DARCO Carbon. by 9:00 p.m. that evening the smell was gone and the citizens of the Northern California City were safe and enjoying the holiday.


The system has been functioning at the Northern California Waste Water Treatment Plant for three months now and everyone is very satisfied. The General Manager said, “I am thankful to Envent for its expertise in engineering and being incredibly responsive”.
