Patent ID: 8491789

Claim:
A system for decontaminating fluid media, the system comprising: a source providing fluid media contaminated with toxic natural organic matter; a photocatalytic decontamination subsystem configured to oxidize the toxic natural organic matter via a photocatalytic process into non-toxic natural organic matter having a molecular weight low enough for biodegrading said non-toxic matter and having no residual oxidants; a biological decontamination subsystem configured to immediately receive the contaminated fluid output from the photocatalytic decontamination subsystem, and employing a biological agent to biologically degrade the low-molecular weight non-toxic natural organic matter in the contaminated fluid to a concentration sufficient to prevent the formation of trihalomethanes or haloacetic acids; and a disinfectant sub-system configured to disinfect the fluid output from the biological decontamination subsystem, the disinfectant sufficient to remove substantially all remaining non-toxic natural organic matter and biological agent, wherein the biological decontamination subsystem comprises a biologically active activated carbon bed.
