Patent ID: 8465653

Claim:
A method for treating marine wastewater, the method comprising: pumping a wastewater slurry into a wastewater collection tank, the slurry comprising suspended solid particles, organic and inorganic matter, bacteria and entrained gases; automatically commencing routing the slurry by a macerator pump for maceration in response to a wastewater level sensor detecting a pre-determined upper threshold level of the slurry in the wastewater collection tank; piping the macerated slurry to an electrolytic cell; oxidizing and disinfecting the macerated slurry piped to the electrolytic cell; adding a defoaming agent to the oxidized and disinfected slurry prior to piping it to an electrocoagulation cell; facilitating, in the electrocoagulation cell, flocculation of the solid particles suspended in the oxidized and disinfected slurry; periodically subjecting the electrocoagulation cell to an automated combined air and water purge, the purge flushing particulate contaminated accumulated on one more electrodes in the electrocoagulation cell; routing the flocculated slurry to a primary settling tank for separation of a floc-containing sludge and a substantially clarified supernatant; piping the substantially clarified supernatant to a secondary clarifying tank, the secondary clarifying tank having sloped walls to facilitate further separation of the sludge and the substantially clarified supernatant; withdrawing the sludge through basal ports on the settling and clarifying tanks; continually measuring turbidity levels of the withdrawn sludge, the sludge withdrawal automatically halted on the condition that the turbidity level measurement equals a pre-determined value; and discharging the substantially clarified supernatant from the clarifying tank as a treated effluent.
