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, conventional and/or treatment:
“Men hear gladly of the power of blood or race. Every body likes to know that his advantages cannot be attributed to air, soil, sea, or to local wealth, as mines and quarries, nor to laws and traditions, nor to fortune, but to superior brain, as it makes the praise more personal to him.”
—Ralph Waldo Emerson (1803–1882)
“The mastery of one’s phonemes may be compared to the violinist’s mastery of fingering. The violin string lends itself to a continuous gradation of tones, but the musician learns the discrete intervals at which to stop the string in order to play the conventional notes. We sound our phonemes like poor violinists, approximating each time to a fancied norm, and we receive our neighbor’s renderings indulgently, mentally rectifying the more glaring inaccuracies.”
—W.V. Quine (b. 1908)
“I feel that any form of so called psychotherapy is strongly contraindicated for addicts.... The question “Why did you start using narcotics in the first place?” should never be asked. It is quite as irrelevant to treatment as it would be to ask a malarial patient why he went to a malarial area.”
—William Burroughs (b. 1914)
