Abstract
Apparatuses, systems, and methods related to water treatment are generally described. In particular, clarifiers that may improve solids thickening and related systems and methods are disclosed.
Claims17
A clarifier for a water treatment system, the clarifier comprising:
- a separator region fluidically connected to an inlet of the clarifier and a first outlet of the clarifier;
- and
- a thickening region below the separator region, wherein the thickening region comprises:
- a rotatable shaft,
- protrusions extending outward from the rotatable shaft, and
- a second outlet fluidically connected to the thickening region and positioned between a first section of the rotatable shaft and a second section of the rotatable shaft.

A clarifier for a water treatment system, the clarifier comprising:
- a separator region fluidically connected to an inlet of the clarifier and a first outlet of the clarifier;
- and
- a thickening region below the separator region, wherein the thickening region comprises:
- a rotatable shaft,
- protrusions extending outward from the rotatable shaft, and
- a second outlet fluidically connected to the thickening region and positioned in a central portion of a clarifier bottom.
3 more elements
A method of operating a clarifier for a water treatment system, the method comprising:
- separating, within a separator region of the clarifier, at least a portion of suspended solids from an aqueous inlet stream to produce:
- a first product enriched in water relative to the aqueous inlet stream, the first product directed to a first outlet of the clarifier, and
- a second product positioned below the separator region of the clarifier, the second product enriched in solids relative to the aqueous inlet stream, the second product having a solids content of 2% by weight or greater and directed to a second outlet of the clarifier.
A method of operating a clarifier for a water treatment system, the method comprising:
- separating, within a separator region of the clarifier, at least a portion of suspended solids from an aqueous inlet stream to produce:
- a first product enriched in water relative to the aqueous inlet stream, the first product directed to a first outlet of the clarifier, and
- a second product positioned below the separator region of the clarifier, the second product enriched in suspended solids relative to the aqueous inlet stream such that the ratio of a mass percentage of the solids in the second product to a mass percentage of solids in the inlet stream is at least about 20 to 1.
