tratamento de água marinha residual

摘要

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.
