Methane Digesters - San Jose Santa Clara Water Pollution Treatment Plant tour -4
Digesters
The pollutants and solid material removed during all three treatment steps are separated from the liquid flows in digester tanks.
It takes 25 to 30 days for anaerobic bacteria to stabilize unwanted material and reduce the pathogens and other disease-causing organisms in the solids. Anaerobic bacteria operate best without oxygen and at about 98 degrees.
Digesters produce methane gas, which meets 35 percent of the Plant's energy needs.
