Biosolids Loading Facility, a.k.a. Sludge
12000 Vista del Mar
Plya del Rey (Los Angeles), Los Angeles County, California
The Hyperion Treatment Plant treats almost all of the sewage from the City of Los Angeles, as well as many other nearby cites.
When the sewage first comes into the plant it goes into a settling tanks where the solids are allowed to settle out. The settled solids are then moved into digesters that produce 7.5 million cubic feet of Methane per day which is converted into electricity. The digested solids are then moved into separators where the juice is removed with a centrifuge to produce the cake (because it can bear some resemblance to chocolate cake). The juice is sent back to the settling tanks for another round through the system and the cake is sent here to be loaded into trucks. There is a excellent diagram of the process here.
Cake is the term people in the business use for sludge. People in the industry did not think name toxic sludge was great PR, so there is now an industry wide effort to rebrand it as biosolids.
There are 635 tons/day of biosolids that are loaded into trucks here. Of that 500 tones/day are sent to Green Acres Farm in Kern County near Bakersfield where it is used to fertilize alfalfa, wheat, sorghum, and corn for cattle feed.
I want to thank my friend and dive buddy Chris Cervellone who is the engineer in charge of construction at a similar facility in Orange County for identifing this and going over the process wiuth me. He his a man who really knows s#!@.
