A UV ballast water management system is a means for controlling and managing the ballast water on ships to prevent the spread of harmful marine organisms. Ships use ballasts, which are large water tanks filled with sea water and located in strategic areas around the ship, for balance depending on the weight of their cargo.
Ships will
pick up ballast water while removing cargo in one port to offset the weight
loss while traveling through the ocean. The problem with this is that along
with filling their ballasts with oceanic water, marine organisms, including
harmful marine life and microorganisms, come with it.
Why a UV Ballast Water
Management System is Important
These
hitchhikers are known to wreak havoc on the ecosystem in which they are
released. When ships reach another port and release their ballast water to add
cargo, these foreign marine lives take hold and take over in an environment
where they have no natural predators. Foreign invaders altering natural marine
ecosystems through contaminated ballast water is recognized as one of the
greatest threats to the sustainability of our planet’s oceans.
It is
estimated that more than 79 million tons of ballast water is discharged at
ports of call near the US coastline alone. Not only does harmful ballast water
invade and pose a threat to coastal ecosystems, but also poses a real danger to
humans as well. Contaminated ballast water spreads diseases which affect
humans, causes insurmountable economic damage by destroying fishing industries
entire towns depend upon and requires massive cleanup efforts.
Seawater in
ballast tanks contains many harmful pathogens and microbes which pose a real
safety risk to humans. Seawater taken in as ships ballast water has been proven
to contain harmful diseases such a Cholera which is a quick spreading disease
that can be fatal for nearly 50% of people it infects. Ballast water has been
known to spread toxic algae, jellyfish which completely destroy fishing ports,
mussels which attach to structures like dams, and harmful marine microorganisms
including viruses and bacteria naked to the human eye.
Ballast Water Management
Convention Requirements
The International Maritime
Organization (IMO) is a specialized agency within the United Nations which is
tasked with the responsibility of establishing safety, security and preventing
marine and atmospheric pollution by ships worldwide. The Ballast Water Management
Convention (BWMC) is a landmark effort to halt the spread of
invasive aquatic species.
The BWMC
was first adopted by the IMO in 2004 as an international effort to control and
manage ballast water and sediments from all ships. Since its adoption, the BWMC
has had several technical guidelines and updates to support shipmasters, ship
owners and port authorities.
The biggest
news for the BWMC is the recent ratification of more than 65 states which
represent more than 70% of the total world tonnage and requires all ships
traveling through international waters to maintain a ballast water management
system. These recent requirements were enforceable September 8, 2017, and are
to be implemented over time for existing ships and immediately for all newly
constructed vessels.
The BWMC
obligates all parties to undertake comprehensive actions to reduce or eliminate
the transfer of harmful aquatic pathogens and organisms through the control and
management of ballast water and sediments. Port State control officers have the
ability to inspect ships to verify an approved ballast water management plan, a
valid certificate and to inspect the ballast water record book or sample the
ship’s ballast water.
Ballast Water Management System
Technologies
Ballast water treatment methods include mechanical
filtration and UV ballast water management systems, often used together for
highly effective control and elimination of harmful marine organisms.
Ultraviolet (UV) germicidal lamps are proven to instantly eradicate viruses,
bacteria and microorganisms naked to the human eye. UV ballast water treatment
technology offers many advantages to shipmasters and shipowners.
UV ballast
water management systems are approved by the US Coast Guard and the IMO, and
offer the following advantages:
·
Simple operation with very low maintenance
·
Economical, fast and efficient technology
·
Eco-friendly, chemical free safe process
·
No need to handle, store or transport dangerous
chemicals
·
No impact to the environment
UV ballast water treatment technology is safe and
effective, requires a small footprint suitable for smaller vessels and is very
low maintenance with long-lasting UV germicidal lamps.
LightSources Offers High
Performance UV Germicidal Lamps
LightSources is a leading global
authority on UVC germicidal lamp development and solutions for
a wide range of applications. We have partnered with many of the largest
providers of ballast water treatment systems in the world to provide
high-quality UV germicidal lamps and components for newly constructed ships or
alterations to existing ships.
Our Low
Pressure (LP) Pellet Amalgam lamps are designed with proprietary LongLIfe™
technology providing an increased efficiency of 30 to 35% over other comparable
lamps. Our Medium Pressure UV (MPUV) germicidal lamps provide an even smaller
footprint with proven durability and effectiveness. UV radiation emitted at
precisely 254 nm is proven to quickly destroy harmful germs, viruses and
bacteria by instantly destroying the DNA of these cells, rendering them
harmless and unable to replicate.
