Sewage Air Pumps
This is one of four large air pumps at the San Jose/Santa Clara sewage treatment plant. The motors run off the methane gas that is excreted as waste by anaerobic bacteria in the solid waste digester. These pumps bubble air through the dark grey/brown liquid that enters the sewage plant, feeding the aerobic bacteria that decompose the organic material and ammonia. Those bacteria remove 90% of the wastewater impurities and produce a reusable biosolid for soil.
After 18 hours of bio-processing and filtration, 99% of the impurities have been removed, in a process that mimics the way nature purifies water, but at a greatly accelerated rate.
