De Nora Wins Contract for BWTS Retrofits

Maritime Activity Reports, Inc.

November 3, 2015

De Nora, a supplier of equipment for seawater electrochlorination, said it has been awarded a contract to provide its BALPURE ballast water management system by one of North America’s major oil tanker operators.

The BALPURE Twin BP3000-C systems, capable of treating ballast water flow rates up to 6,000m3/h,  will be retrofitted in five crude oil tankers ranging in size from 125,000 DWT to 141,740 DWT. The installations will take place from mid-2016 to 2018.
BALPURE utilizes electrolytic disinfection technology to provide ballast water management. In addition to being IMO Type-Approved and USCG AMS-Certified, the system has been Bureau Veritas Type-Approved and ABS Design Assessed. De Nora Water Technologies has applied for USCG type Approval and is well positioned to receive this certification soon, the company said.
Using a slip stream approach, whereby 0.5 to 1 percent of the total ballast water flow is used to generate the hypochlorite disinfection solution, the BALPURE system can be remotely mounted away from critical ballast systems. The slip stream approach, coupled with a design that requires treatment only during the uptake of the ballasting cycle, uses significantly less electric power when compared to competing technologies – ensuring low operational costs. In addition, these units are equipped with a proprietary coating developed by De Nora that ensures self-cleaning as well as high performance in very low temperature / low salinity waters.
With 3,500 electrochlorination installations in 60 countries, DeNora is the world’s largest manufacturer of electrochlorination systems. DeNora systems produce more than 1.3 million kilograms per day of sodium hypochlorite from seawater. The company has engineering, production and assembly facilities in Italy, the United States and China.
