Abstract
A liquid waste treatment system includes: a baffle tank subsystem for particle settling; a preprocess tank subsystem downstream of the baffle tank subsystem; a process tank subsystem downstream of the preprocess tank subsystem; and a storage tank subsystem downstream of the process tank subsystem for the storage of treated liquid. A Microbial Fuel Cell (MFC) processing module may be included and may be inserted into the preprocess tank subsystem or implemented in a second process tank downstream of the process tank subsystem. A faster disinfection may occur in the process tank subsystem, and a slower disinfection may occur in the second process tank according to distinct respective kill curves. An electrochemical cell may be operated in a pulse mode in liquid waste in a pulsed mode.
