Severn Trent De Nora offers the BALPURE® ballast water treatment systems. The patent-pending system generates biocides, meters and analyzes the residual level of both biocides and neutralizing agents and logs the performance of the overall ballast water treatment system. With international, national, state and local environmental agencies worldwide taking action to regulate the discharge of ballast water arriving in ships coming from overseas ports, the BALPURE® system has proven to be an effective, economical and high-capacity device to treat this water with no adverse effects on the environment. Third party testing of the BALPURE® system has confirmed effluent quality that meets proposed International Maritime Organization ballast water standards.
Ballast Water Treatment Systems: The introduction
of aquatic nuisance species into coastal marine and estuarine waters comes from
a variety of sources. However, because of the large volumes and frequency of use,
ballast water is currently the most frequently cited method for the worldwide transference
of non-indigenous organisms. International agencies such as the International Maritime
Organization (IMO), United States Coast Guard (USCG), and U.S. federal and state
governments are combating the problem by mandating ballast water exchange in the
open ocean or utilizing ballast water treatment systems.
Ballast Water Exchange is time consuming, costly, and is often a dangerous operation
depending on conditions. In 1996, the National Research Council identified the use
of biocides as an option for treatment of ballast water. Severn Trent DeNora, with
25 years experience, is the world leader in the design and manufacture of electrolytic
systems to generate biocides (disinfectants) from halide ions present in seawater,
saline, and estuarine waters. Our systems are installed world wide to provide economical
solutions for the control of biofouling in power plants, offshore oil and gas production,
and any other application where effective, safe treatment of seawater is required.
We have taken our proven technology along with years of marine equipment experience and applied it to the treatment of ballast water. Our BALPURE® system has been extensively tested by the University of Washington and certified laboratories, while demonstrated as an effective, economical device to treat ballast water with no adverse effects on the environment. This demonstration includes a full range of EPA specified Whole Effluent Toxicity (WET) tests and disinfection by product analyses which clearly substantiate the efficiency of the BALPURE® system.
A BALPURE® system consists of five key components:
- Oxidant Generator
- Oxidant on-line / real time analyzer
- Oxidant Neutralization System
- Sulfite on-line / real time analyzer
- Data Logger for key operating variables
