Europort 2017 Video Spotlight: Ballast Water Treatment

At Europort 2017, Juha Kiukas (Trojan Marinex Sales Director) had the opportunity to take GREEN4SEA on a quick tour of the booth we shared with our channel partner GEA and answer a few questions about the Trojan Marinex Ballast Water Treatment system.

Watch as Juha provides insight into streamlining system installation, ways to overcome retrofit challenges, and the importance of comprehensive crew training.

Dispelling The UVT Myth

Ultraviolet light (UV) can treat extremely turbid ballast water, as long as the treatment system is engineered to the highest of standards. Unfortunately, misconceptions about UV’s ability to treat poor quality water are common. However, UV disinfection is extensively proven to treat wastewater, and, in most cases, wastewater is of poorer quality or lower UV transmittance (UVT) than ballast water.

What is UV Transmittance (UVT)?

UV systems not designed for poor water qualities will have dark zones.UVT is the ratio of light entering the water to that exiting the water. Simply put, water with high UVT (e.g., 90%) is relatively clear, allowing more UV light to reach the organisms you are trying to treat. As water quality decreases, the UVT is reduced (e.g., 50%) which in turn reduces the amount of UV light that is able to penetrate and provide treatment.

Every Port is Different

No matter where in the world your vessels trade – whether it’s clear seawater or turbid fresh water – your ballast water treatment system has to work. And, as you know, water quality varies from port to port and day to day.

Water quality varies from port to port.Different water quality parameters become more or less important depending on the type of ballast water technology used. In the case of Electrochlorination systems, the salinity, temperature and organic content of the water will have a dramatic impact on the overall efficacy of the system. For UV systems, UVT is the most important parameter impacting the effectiveness of the system.

High UVT Values Limit System Applicability

A conventional ballast water treatment system – utilizing a land-based-designed UV system (i.e., designed to treat drinking water with 85% UVT) – won’t be able to provide the same treatment performance in lower UVT (e.g., 50%) water. More equipment would be required to provide the same level of performance, and more equipment means increased power draw and space requirements.

A high UVT value limits system applicability.Many existing IMO Type Approved systems have been tested in higher clarity water (high UVT). It is expected that these systems will not be approved to treat lower clarity waters than to what they have been tested to under USCG regulations. The UVT value will be noted on the Type Approval certificate, significantly limiting the applicability of the system in poorer water qualities. In addition, alarms will be noted in equipment logs every time the UVT value of the ballast water falls below the minimum to which it was tested. Multiple alarms are likely to draw increased attention from Port State Control. The best way to reduce your risk is to utilize a ballast water treatment system that has been tested to low UVT values.

Dispelling The UVT Myth

The Trojan Marinex BWT system is tested and approved to one of the lowest UVT values in the industry, under full flow conditions. This dispels the myth that UV cannot be used in the poorest of water qualities.

Damen Selects Trojan Marinex BWT System For Antarctic Supply & Research Vessel

We are proud to announce that Damen Shipyards has selected the Trojan Marinex Ballast Water Treatment (BWT) system for the Government of Australia’s next-generation Antarctic Supply and Research Vessel (ASRV).

Damen will install a skid-mounted Trojan Marinex BWT 250 on board the Government of Australia’s next-generation Antarctic Supply and Research Vessel.

“At Damen Green Solutions, we partnered with Trojan Marinex to design a ‘plug-and-play’ installation for DSNS,” says Stefhan van Esch Design & Proposal engineer at Damen. “Together we created a bespoke design that mounts the entire BWMS on a 3m by 1m skid that can be easily and quickly fitted into the available footprint in the engine room. Prior to leaving the manufacturing works it will undergo a factory acceptance test, leaving the simple matter of connecting up the power and the main pipes once it is aboard the ASRV. The Trojan Marinex BWT 250 will then be ready to disinfect and treat up to 250m³ of seawater an hour.”

Low power draw and efficient operability in extremely cold water temperatures were among the deciding factors in the system selection process.

Ballast Water Treatment Q & A

Trojan Marinex understands the importance of providing safe, efficient ballast water treatment to help prevent the potential spread of invasive organisms as ships travel from port to port. With a unique system that combines filtration and UV into a single unit, we offers shipowners a compact, purpose-built ballast water treatment system that meets international standards.

At Nor-Shipping 2017, Andrew Daley (Trojan Marinex Product Specialist) sat down with John Snyder, the editor of Marine Log, to discuss the ballast water treatment industry and the in-depth research and science behind the Trojan Marinex Ballast Water Treatment system.

Listen in to get the answers to these questions:

  • Why are ballast water treatment systems needed?
  • Where is Trojan Marinex at with respect to various Type Approval processes?
  • What types and sizes of ballast water treatment systems does Trojan Marinex offer?
  • How does the Vessel Incidental Discharge Act (VIDA) relate to ballast water treatment in the United States?
  • How has the Trojan Marinex Ballast Water Treatment system evolved over the past few years?
