ABSTRACT:
A water treatment multi-stage process and apparatus thereof for removing dissolved, colloidal, volatile, suspended and living contaminants from water, wastewater or sludge streams which includes chemical feeding, static mixing, flotation chemical monitoring and optimization, gas pressurization, hydraulic flocculation, sedimentation, flotation, and final water treating by converting dissolved solids to insoluble forms by oxidation and chemical precipitation, coagulating and clarifying colloidal substances and microorganisms, magnetic or electronic treating the remaining contaminants in the water to produce a purified water. A majority of insoluble suspended particles in the water are collected by sedimentation and flotation separation procedures and subsequently dewatered and dried and all necessary unit processes operations are incorporated into an apparatus with common walls and drive mechanisms for improviding the water treatment efficiency, reducing secondary pollution caused by scums/sludges, and eliminating the needs of a separate mixer, monitor, flocculator, pressure vessel, clarifier, aerator, biofouling preventor, and scale and corrosion controller.
