Integrated water treatment system

Abstract

A water treatment system comprising a single structural body within which at least two functionally distinct treatment stages are arranged as nested zones in flow communication with one another, providing a continuous treatment sequence in place of discrete, sequentially connected components. In one embodiment, the system includes a flocculation unit, a dissolved air flotation (DAF) unit comprising one or more annular or arcuate compartments defining at least one flow channel at least partially surrounding a central region, and a filtration stage comprising one or more filter modules positioned within the central region. Clarified water from the DAF unit is directed to the filter modules via a flow path from a downstream end of the flow channel. The nested architecture permits different treatment processes to be configured within the zones according to the characteristics of the source water, achieving structural integration, compact footprint, and modular construction within a single unit.
