Clarifiers
are the principle mechanisms for solid /liquid separation in
primary, intermediate and final wastewater clarification
applications.
-
SPS manufactures many types of clarifier mechanisms to best suit the
clarification processes.
-
Steel tanks or shells are also available. The most widely used clarifiers are
depicted below for general information.
-
All types available
in sizes 0 - 200 ft diameter.

● in conventional scraper clarifiers the blades are
mounted at 45º
on the structural arms to direct the solids in
stepping blade
lengths to a central hopper for removal.
● in rapid sludge removal clarifiers one or two
spirally constructed
blades of varying depths are utilized. The
time of directing the solids
to the hopper is drastically cut to
one or two revolution periods.

|
|
| ● in suction header design the sludge is directed into
a tapered rectangular header through a hydraulically sized system
of orifices and then into the submerged sealed manifold for rapid
sludge removal. |
● in the suction
pipe design the sludge is conveyed through piping from
the plow blades nozzle
to the RAS well, accessible from the bridge,
and the sludge flow
can be observed and adjusted for optimum operation.

| sPs FLOCCULATING CLARIFIERS
have applications in both fresh water and wastewater treatment
clarification processes. The introduction of chemical additives into
an oversized feedwell, which provides a longer detention time,
enhances formation of floc. Variable speed turbine or paddle type
mixers are furnished for gentle agitation allowing uniform chemical
dispersion and growth of floc particles. Bigger floc settles faster
and better, insuring a high degree of clarification |
