Wastewater clarification relies on gravity separation characteristics
of suspended matter within the wastestream. Solids suitable for separation
using a clarifier must be of a settle-able nature. The clarification
process promotes solids to settle to the sludge collection chamber at
the bottom of the tank, allowing clear effluent to decant from the top
of the clarification tank.
The WESCOR clarifier utilizes inclined plate technology for efficient
solid/liquid separation. The inclined plate clarifier design permits
increased wastewater throughput while occupying a minimum equipment
Wastewater enters the clarifier by means of pump, or gravity flow.
When necessary, wastewater is chemically pre-conditioned in the integrated
flash & floc mix tanks to maximize floc size & settling characteristics.
Conditioned wastewater then flows into the centre portion of the clarifier
plate tank. Flow is distributed across the bottom of the plate pack
in a quiescent manner to initiate the settling process. As the wastestream
moves upwards through the plate tank, flocculated solids settle onto
the plates, and then fall by gravity along the surface of the inclined
plate to be collected in the lower sludge chamber. Solids collected
in the sludge chamber are removed by pump through-out the operation
at intervals determined by the control system. Clarified water flows
out the effluent weir at the top of the plate tank.
