A process for self-cleaning an electrolytic cell involves introducing a stream of seawater into the electrolytic cell having at least one cathode and one anode. The cathode and anode are substantially fully coated with a coating composition. A forward bias is applied between the anode and the cathode at a first current density as seawater flows between the electrodes. Subsequently, a reverse bias is provided at the cathode. The reverse bias is provided at a second current density that is lower than the first current density. When the reverse bias is applied, the polarity of the cathode is reversed for a short duration. This facilitates the generation of a small amount of hydrochloric acid at the previous cathode surface causing the dissolution of calcium, magnesium or other deposits on the surface of the electrodes without damaging the coating composition on the electrodes.

The invention relates to a system and method for treating wastewater onboard a marine vessel or other limited space application where wastewater treatment is required. In one embodiment of the invention, two polar opposite wastewater treatment processes are incorporated into the same treatment system. The system is a hybrid treatment unit that combines a conventional wastewater treatment using a moving bed biofilm reactor (MBBR) process-based biological treatment unit in combination with a novel electrochemical advanced oxidation process (EAOP) via an in-situ sodium hypochlorite recirculation. The clarified and disinfected effluent from this hybrid treatment unit is filtered to remove residual TSS. The filtered and disinfected effluent is discharged after dechlorination/neutralization. On-site maintenance disinfectant can be produced via the electrochemical/electrochlorination/electro-oxidation process and used for both treatment unit cleaning and disinfection. Additionally, the treatment unit provides a wholly separate stream of electrolysis generated disinfectant for surface disinfection purposes.

Methods and systems for treating wastewater. Wastewater slurry collected in a tank is routed by a macerator pump. The macerated slurry is piped to an electrolytic cell to oxidize and disinfect it. The slurry is then piped to an electrocoagulation cell. Suspended solid particles are flocculated in the electrocoagulation cell. The flocculated slurry is routed to a primary settling tank for separation of sludge and a substantially clarified supernatant. The supernatant is piped to a secondary clarifying tank to facilitate further separation of the sludge. The sludge is discharged to a sludge collection tank. The turbidity levels of the sludge discharged is continually monitored. When the turbidity level equals a pre-determined low value, the sludge discharge is stopped. The substantially clarified supernatant may be discharged as an effluent following dechlorination.
