EcoOne® BWMS

As the global shipping industry continues to face unprecedented pressure to reduce emissions, shipowners are seeking innovative solutions that can help them meet their decarbonization goals. That's where the EcoOne® Ballast Water Management System comes in - a highly effective, low-powered treatment technology designed to significantly reduce the carbon footprint of ships.

Ecochlor is one of the leading providers of ballast water management systems and the only one that uses the highly effective ClO2 treatment technology with very low power requirements. Our systems are reliable, cost-effective, and easy-to-use, enabling ships to operate in all water conditions while maintaining high levels of flexibility in trade routes.

The EcoOne® BWMS is available in filterless mode or hybrid options, as well as in the EcoOne® Container Unit. This affords you even more choices when it comes to choosing the ballast water management system that is best suited for your vessel.

All our BWMS come with the same BWMS reliability, high level of efficacy and superior global service. One major benefit of choosing Ecochlor is the simple operation for your crew!

Other benefits include:

  • NO TRO sensors
  • NO electrodes
  • NO complex power requirements

Additionally, with our system you will be using a low power and carbon footprint solution that helps you reduce your environmental impact and lower emissions.

The EcoOne® Filterless BWMS treats with a single-step process of disinfection with chlorine dioxide (ClO2) alone. Vessels using this system can operate anywhere in marine and brackish waters (i.e. > 1 PSU) with no restrictions on temperature or turbidity.

The EcoOne® Hybrid BWMS offers the choice of dual modes, filtration & ClO2 or ClO2 alone. This system allows shipowners to operate their BWMS either with or without a filter. This option is suited for shipowners who wish to have the flexibility of unrestricted operation globally with the convenience of a no-filter system.

The EcoOne Container BWMS uses a single unit to serve four quadrants or substations with one-way, small diameter piping for offshore installations. There is no filter, no treatment for de-ballasting with gravity ballasting possible. One containerized BWMS can serve multiple rigs.

Chlorine dioxide (ClO2) is a powerful biocide that reacts with living cells by first penetrating the cell wall and then reacting with the material within the living cell in order to kill the organism. ClO2 has been used in a wide variety of land-based treatment applications, including drinking water, municipal waste processing, food, pulp, and paper production for over 70 years. ClO2 offers a number of advantages over other ballast water disinfection methods and techniques; it is effective on all aquatic organisms, including bacteria and other pathogens, and is effective anywhere in the world with no limitations when it comes to temperature, salinity or turbidity.

While both chlorine (bleach) and ClO2 are oxidizing agents, they disinfect ballast water in two fundamentally different ways.
ClO2 targets living cells and has very limited reactions with non-living organic matter present in ambient water. It works exceptionally well in waters with high levels of organic matter (“dirty” or turbid waters) and produces minimal disinfection by-products.

On the other hand, chlorine reacts with almost any organic material (living and non-living) such as oil, algae, sediments, etc. This means that waters with high levels of organic matter increase the demand for chlorine, leaving less of the chemical available to treat living organisms. This is typically addressed by increasing the dose in “dirty” water. Due to the types of reactions that chlorine has with both organic and inorganic compounds, chlorine has a greater potential to form undesirable disinfection by-products which can pose toxicity risks to both aquatic organisms and humans.
The high levels of chlorine required to treat ballast water comes with operating limitations — neutralization is required to ensure chlorine can be discharged safely and high concentrations of chlorine can damage ballast tanks.

Because ClO2 is not affected by suspended sediments or turbidity, filtration is not necessary to remove sediments prior to treatment with ClO2. This is in contrast to UV or similar technologies that require the removal of sediment for the UV light to disinfect ballast water, and electro-chlorination or similar hypochlorite-based treatment technologies, that require high doses of chlorine to treat “dirty” water. As a result, Ecochlor is uniquely suited to offer a filterless system with very low power consumption and chemical dose that also protects vulnerable tank coatings.

No. TRO sensors are typically used in electro-chlorination and similar chlorine-based BWMS technologies to regulate both the chlorine dose on uptake (in response to varying water conditions) and the neutralizing dose required during discharge. The Ecochlor system uses a fixed, low dose of ClO2 regardless of water conditions. There is no requirement for neutralization on discharge there are no TRO sensors needed.

Ecochlor® BWMSs have some of the highest operating capacities in the ballast water treatment industry. Our current type approvals allow our system to be operated at flow rates of up to 116,200 m3/hour

Yes. Ecochlor receives crew feedback on every ballast operation, demonstrating that over 98% of Ecochlor® BWMSs are operational. Ecochlor’s BWMSs are inherently simple in their design and as we all know in the marine environment, simple means reliable – less equipment means easier operation for the crew and, of course, lower maintenance needs. Plus, we’ve made our already commendably reliable system even simpler and more reliable with the EcoOne® BWMS.

Choosing Ecochlor for your ballast water management system is a smart investment. Our system is reliable, efficient, and easy to use, saving you time and money while also protecting the environment.
