Publication number: 20240083781Abstract: 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.Type: ApplicationFiled: January 21, 2022Publication date: March 14, 2024Inventors: Jose Lopez, Charles Clements, Dana Casbeer, Rudolf Matousek

Patent number: 11613482Abstract: 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.Type: GrantFiled: June 25, 2020Date of Patent: March 28, 2023Assignee: DE NORA MARINE TECHNOLOGIES, LLC.Inventors: Dana Casbeer, Sehul Patel, Harold Childers

Patent number: 11180388Abstract: A method for treating wastewater involves electrolyzing a stream of seawater and wastewater mix within one or more electrolytic cells mounted outside a batch tank. The electrolyzed stream is piped to a quelling chamber which is mounted above the batch tank. A diluted polymer solution is injected at upstream of an in-line mixer piping into the quelling chamber substantially concurrently with the electrolyzed stream. The polymer solution and the electrolyzed stream are dispersed as a fine shower over residual seawater and wastewater in the batch tank. The polymer solution facilitates flocculation of the suspended solid particles and creates a distinct buoyant layer of flocculated solid particles attached with micro bubbles. A substantially clarified effluent is separated from the flocculated layer and neutralized prior to discharge. The flocculated layer is pumped from the batch tank to a dewatering system where entrained solids are compacted to a desired level.Type: GrantFiled: October 31, 2017Date of Patent: November 23, 2021Assignee: INDUSTRIE DE NORA S.P.A.Inventors: Dana Casbeer, Rubin Bariya, Sehul Patel, Rudolf Matousek, Thomas Reeves

Patent number: 10343937Abstract: An electrocoagulation reactor (ECR) apparatus and methods of using the ECR apparatus in the treatment of a fluid stream. The ECR apparatus includes a noncorrosive cylindrical cell housing a plurality of horizontally stacked electrode plates. The electrode plates are held in a pair of grooved, crescent shaped non-conductive inserts. The ECR apparatus further includes two end flanges each having integral flow diverters to facilitate a continuous single serpentine flow of the fluid in the cell. The ECR apparatus further includes a single flow inlet and single flow outlet.Type: GrantFiled: September 30, 2015Date of Patent: July 9, 2019Assignee: De Nora Water Technologies, LLCInventors: Dana Casbeer, Larry Knight, Rudolf Matousek, Rubin Bariya

Patent number: 8668832Abstract: Methods, apparatus and systems for treating wastewater onboard small marine vessels. A pre-determined volume of wastewater generated onboard the vessel is mixed with a larger volume of seawater. This mixture is disinfected and subjected to further oxidation. The excess oxidants are neutralized and the treated effluent is discharged overboard the vessel.Type: GrantFiled: March 19, 2010Date of Patent: March 11, 2014Assignee: Severn Trent de Nora, LLCInventors: Rudolf Matousek, Dana Casbeer, David Hill, Rubin Bariya

Patent number: 8465653Abstract: 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.Type: GrantFiled: November 18, 2009Date of Patent: June 18, 2013Assignee: Severn Trent De Nora, LLCInventors: Rudolf Matousek, Dana Casbeer, David Hill, Rubin Bariya
