Severn Trent De Nora has entered into an exclusive licensing agreement with The Vinson Gavrel Group to use the company’s patented Ecolotron electrocoagulation (EC) reactor in the OMNIPURE™ Series 55 marine sanitation system design. The OMNIPURE Series 55 systems produce a sodium hypochlorite disinfection solution from seawater in the presence of sewage to effectively treat all sewage. Accommodating treatment capacities up to 598 persons for black water and up to 197 persons for black and gray water, the OMNIPURE Series 55 systems range in capacity up to 65 m3/day (17,000 gal/day) as individual units that can also be combined for increased capacity.
The OMNIPURE Series 55 system uses an automatic three-stage process to provide effective electrolytic treatment of black and gray water in accordance with MEPC.159(55) effluent standards and performance tests for sewage treatment plants across a variety of offshore and marine installations. Wastewater leaves the first treatment stage and enters the second stage, which comprises the EC reactor, gas-liquid separator and solids-liquid separation tank. Integrating the Ecolotron EC reactor, which operates under pressure, simplifies the OMNIPURE Series 55 treatment process. The EC reactor allows wastewater to flow from the first treatment stage to the second without the use of a feed pump.
There are several key features which make the Ecolotron EC reactor unique among commercially available EC technology providers. The design of the Ecolotron EC reactor enables it to be completely enclosed for safe installation as part of the OMNIPURE Series 55 system. Additionally, the reactor is easy to access and open for routine maintenance and replacement of the consumed electrodes. The Ecolotron EC reactor also features simple electrical connections.
According to Frank Martin, director of operations of Severn Trent De Nora, “We evaluated other EC cell technologies when we began development of the OMNIPURE Series 55 system to meet the new and then-impending MEPC.159(55) regulations. With the Vinson Gavrel Group’s commitment to electrocoagulation technology, the Ecolotron EC reactor became our technology choice for use in our systems.”
