Advantages Over Conventional Treatment
Conventional treatment settles sludge which is then digested, and then aerates the remaining liquids which use bacteria to oxidise the potential digester fuel, and uses up energy to drive the compressors. The result is that on a standard western treatment works the energy produced from settled sludge digestion is all used by the aeration process, with little power export.
With UASB the aeration the whole process of settlement and digestion occurs in one or more large tank(s). Only the post UASB liquids, with a much reduced BOD needs to be aerated.
This leads to a halving of the aeration energy and a doubling of the power generated from digestion, leading over all to a tripling of power generated.

Famous quotes containing the words advantages over, advantages, conventional and/or treatment:
“A woman might claim to retain some of the child’s faculties, although very limited and defused, simply because she has not been encouraged to learn methods of thought and develop a disciplined mind. As long as education remains largely induction ignorance will retain these advantages over learning and it is time that women impudently put them to work.”
—Germaine Greer (b. 1939)
“When the manipulations of childhood are a little larceny, they may grow and change with the child into qualities useful and admire in the grown-up world. When they are the futile struggle for love and concern and protection, they may become the warped and ruthless machinations of adults who seek in the advantages of power what they could never win as children.”
—Leontine Young (20th century)
“No one who has lived even for a fleeting moment for something other than life in its conventional sense and has experienced the exaltation that this feeling produces can then renounce his new freedom so easily.”
—André Breton (1896–1966)
“I will use treatment to help the sick according to my ability and judgment, but never with a view to injury and wrongdoing. Neither will I administer a poison to anybody when asked to do so, nor will I suggest such a course. Similarly, I will not give to a woman a pessary to cause abortion. I will keep pure and holy both my life and my art.”
—Hippocrates (c. 460–c. 370 B.C.)
