The
Spiravac Clarifier has more than 45 years of successful operation ranging
from 11 feet to 130 feet in diameter, offering solids removal through suction
orifices to ensure rapid return of active solids to the process. Wastewater
enters the Spiravac at the outer wall and is directed along the narrow
raceway formed by the skirt and the outer wall. This flow pattern dissipates
the wastewater’s hydraulic energy as it flows around the raceway and
eventually spirals down under the skirt. Influent enters the main settling
area from the full circumference of the skirt and slowly rises to pass over
the centrally located effluent weirs. The inflow is prevented from flowing
directly to the effluent weir by the specially designed race skirt, which
extends down to approximately two feet above the tank floor. The spiraling
flow pattern makes use of total tank volume for effective solids settling. Like the
Spiraflo, the Spiravac’s peripheral-feed hydraulics have many advantages over
center-feed clarifiers, such as: minimizing the waterfall effect, sludge wall
creep and short circuiting.
