PAES Flashcards
Structures
plant used to process animal wastes or manure to produce biogas and sludge consisting of an inlet/mixing tank, digester, gas chamber and outlet/sludge tank
biogas plant
biogas plant where the digester and gas chamber form one unit
integrated plant
digester and gas chamber form separate units
split type plant
plant with series of digesters
multi digester
plant consisting of digester and a moving, floating gasholder that either float directly in the
fermenting slurry or in a separate water jacket
floating type
closed digester with an immovable, rigid gas chamber and a displacement pit
fixed type
plant consisting of a heat-sealed plastic or rubber bag (balloon), combining digester and
gasholder
balloon type
holding tank; chamber where manure and water are collected, stored and separated from
heavy and nonbiodegradable materials before feeding them into the digester
collecting tank
serves as conveyor of the manure-water mixture or slurry from the mixing tank to the
digester
inlet pipe
any water and air tight container designed for the process of anaerobic microbiological
degradation of organic matter into which the slurry is introduced for digestion and
methanization
digester
division in the digester that prevent the slurry from premature exit into the sludge/outlet
tank
baffle board
agitator; mechanical device inside the digester used to stir the slurry
stirrer
space inside or outside the digester for the collection and storage of biogas
gas chamber
cantilever beam that holds the gasholder/movable cover in position at the desired biogas
pressure
gas holder retainer
serves as conveyor where the effluent or the slurry is forced out
outlet pipe
