Column-supported thickeners
Eimco & Dorr-Oliver column-mounted
thickeners are supported
by a
stationary
center column of steel or
concrete.
The center column supports
the drive and rake mechanisms,
while
the truss extending from the center
pier to the tank periphery supports
the walkway,
power lines and feed
launder. These units are suitable for
basins and raking arms with diameters
of up to 600 feet (180 m).
