Abstract: A system for processing contaminated water is disclosed. The system processes contaminated water, yielding water that is suitable for (1) re-use in an application (e.g., an industrial application) that requires water but does not require potable water, or (2) discharge (e.g., discharge into the environment), or (3) both (1) and (2). All embodiments of the system include a separator for removing sediment and large suspended solids from contaminated water; a coagulant delivery device for delivering coagulant to contaminated water; a clarifying device for removing fine suspended solids from contaminated water; an adsorbing device for removing organic substances from contaminated water; a deashing device for removing dissolved inorganic salts from contaminated water; and a disinfecting device for destroying microorganisms present in contaminated water.
