Ballast Water System Solutions

Originally posted at: https://www.light-sources.com/blog/ballast-water-system-solutions/

A ballast water system is used in ships and large vessels to maintain balance and ideal buoyancy while loading or unloading cargo and while sailing through the water. Due to the increase in global shipping, especially in the past decade, 90% of all global trade is transported by sea. The number of ships using ballast water has increased significantly and is a very common practice.

While ballast water may provide ideal buoyancy and improve the safe operation of ships, this practice brings very dangerous threats to fishing ports, communities, local environments, and economies. When ships pick up ballast water in one port and release it in another, the introduction of invasive aquatic species and harmful marine organisms seriously threatens the sustainability of marine ecosystems. In fact, untreated ballast water exchange is considered to be one of the top four threats facing the sustainability of the world’s oceans.

The Ballast Water Management Convention (BWMC) adopted by the International Maritime Organization (IMO) establishes procedures for the safe handling and treatment of ballast water to prevent the spread of harmful bio invasions. The convention was adopted by Finland in 2016, triggering the ratification for international compliance. While the United States has not been a party to the BWMC, the U.S. has adopted stricter regulations than those imposed by the IMO and requires all ships discharging ballast water in US waters to maintain a US Coast Guard-approved ballast water treatment system.

How Ballast Water Systems Work

Since the introduction of steel hulls in ships, the practice of using ballast water has become commonplace. A large vessel may have the capacity to hold millions of gallons of water in its ballast. Ships may discharge ballast water tanks to improve handling conditions such as discharging ballast water to allow passage through a shallow area or discharging forward tanks only to raise the bow when in turbulent open seas.

While there is some controversy as to the best method of maintaining buoyancy and safe handling in ships, the fact remains that using ballast water is a very common practice in the majority of ships and tankers worldwide. Some experts would like alternative methods for the safe handling of ships as releasing ballast water takes time and not every situation allows time to discharge treated ballast water tanks. The ballast water system consists of water intakes, strainers, pumps, distribution pipes, ballast water holding tanks, chosen treatment technology, and a discharge system including all valves, sensors and controls.

Discharge Water Threats and Catastrophes

The millions of gallons of seawater drawn into ballast water systems have had catastrophic results on the affected areas of discharge. Invasive species including marine life and plant life are able to survive and travel in untreated ballast water tanks and seriously threaten communities where these bio invaders are released. Examples of ships’ ballast water wreaking havoc with catastrophic results include:

·        In 1988, a ship released ballast water into the Great Lakes system along with Zebra Mussels which invaded Lake Saint Clair. The invading Zebra mussels eliminated all native varieties and clogged underwater industrial equipment, causing an estimated $7 billion in damages.

·        Toxic algae comes in various red, brown, and green species with several species having been transferred through ships’ ballast water. Toxic algae can form harmful algae blooms that kill native marine life through the release of toxins and oxygen depletion. Toxic algae contaminates beaches which impacts recreational activities and tourism as well as affecting fishing industries. Consuming shellfish that have been contaminated with toxic algae has been proven to make people severely ill and even cause death.

·        The European Green crab is native to the European Atlantic Coast but has been introduced to the United States, Japan, South Africa, and South Australia through contaminated ballast water. These invasive crabs are highly adaptable and quickly become a dominant species that displaces all native crabs along with depleting many other species of marine life.

These are just a few examples of the harmful effects that contaminated ballast water has had on the environment, human health, and economies. It is clear to see why the United States along with the IMO is enforcing ballast water systems that remove harmful invading species, algae, bacteria, and harmful sentiments.

Water Treatment Methods and Solutions

Ballast water treatment methods are faced with challenges such as the need to discharge ballast water quickly when loading cargo or in emergency situations. Ballast water tanks must pass ballast water through a treatment system quickly while effectively killing harmful organisms. Some ballast water treatment solutions include:

Rules on where ballast water may be discharged or exchanged. Ballast water discharge is governed by local, national and international law. While the most recent ratification of the BWMC requires all newly constructed vessels to contain a ballast water treatment system, interim solutions require ships to exchange ballast water mid ocean. The United States requires all ships to exchange ballast water beyond the Exclusive Economic Zone (EEZ), at least 200 nautical miles from shore and in an area that is at least 2,000 meters deep.

Mechanical filtration. Physical treatment solutions such as filtering the water with a fine filter system to prevent small invasive species from passing through it is only partially effective. The filtration system clogs quickly and does not stop bacteria or viruses naked to the human eye.

Chemical treatment. Treating ballast water with chlorine bleach and other toxic chemicals is one of the earliest methods of ballast water system treatments and is also one of the most dangerous. Releasing these chemicals into natural seawater will also harm existing organisms as the toxic level required to treat the millions of gallons in ships’ ballast water systems will create toxic levels for aquatic life near the releasing area.

UV ballast water treatment technology. Ultraviolet (UV) radiation is used in a multitude of applications worldwide and has highly effective germicidal properties. UV radiation, when emitted at 254 nm, instantly penetrates cells of living organisms and alters the DNA to render them harmless without the ability to replicate. UVC germicidal lamps are used in many water disinfection applications as well as in air treatment systems and surface disinfection processes.

Advantages of UV Ballast Water Treatment Systems

Effectiveness. UV radiation is highly effective in eradicating viruses, bacteria, harmful marine organisms, and bio invaders naked to the human eye. UV radiation is effective regardless of the temperature or salinity of water.

Small Footprint. UV lamps used in ballast water treatment systems are designed with a small footprint to fit into compact water treatment systems, which can be custom-designed to match the space available in each vessel.

Little to no maintenance. A UV ballast water treatment system is easy to install and easy to maintain. Unlike chemical treatment systems, with UV water treatment systems there is no need to purchase, store, or dispose of harmful chemicals.

Safe. While UVC radiation is highly effective in germicidal applications it is completely safe for humans and poses no risk with harmful by-products such as those generated from chemical treatment.

Hospital UV Disinfection: Highly Effective with Automatic Solutions

Originally posted at: https://www.light-sources.com/blog/hospital-uv-disinfection-highly-effective-with-automatic-solutions/

Healthcare facilities face serious challenges with mitigating the spread of germs and are seeking enhanced methods of disinfection such as hospital UV disinfection systems. Healthcare-associated infections (HAIs) cause nearly 100,000 deaths in the U.S. annually with approximately 1 in 25 people contracting an infection from their hospital stay. HAIs cause unnecessary deaths and put patients and staff at an increased risk.

The hospital environment plays a critical role in the transmission of pathogens, as many harmful viruses and bacteria can remain on surfaces for weeks, months, and even years. Superbugs which are resistant to antibiotics such as Methicillin-resistant Staphylococcus aureus (MRSA) and Vancomycin-Resistant Enterococci (VRE) pose additional challenges to keeping patients and hospital staff safe from infection.

Challenges in Disinfecting Hospital Rooms and Surfaces

Many challenges exist in preventing the spread of infection in hospital rooms and surfaces. Disease outbreaks have been traced back to many sources such as thermometers, blood pressure cuffs, sinks, and counters in patient rooms, and computer keyboards. This puts hospital staff at risk of contracting and spreading dangerous pathogens.

Hospital staff are expected to thoroughly clean patient rooms and use disinfectants known to kill pathogens of a previously infected patient. Some chemical disinfectants may require a long exposure time to provide effective disinfection and may not even be applied to all infected surfaces. Cleaning materials themselves such as mops or cleaning cloths may also become a source of transmission, spreading harmful pathogens rather than eliminating them.

Due to these challenges facing the healthcare environment with ineffective chemical treatments and the resistance of certain pathogens, it is imperative to incorporate enhanced disinfection with hospital UV disinfection.

Enhanced Disinfection with Hospital UV Disinfection

UV disinfection in hospitals is becoming an extremely popular method of assuring protection against the spread of harmful diseases, with a high rate of efficacy. According to a study published by Cambridge University, UV disinfection systems reported >99.99% effectiveness in eliminating resistant pathogens such as:

·        Middle Eastern respiratory syndrome coronavirus (MERS-CoV) which had a reported mortality rate of approximately 36%

·        Severe acute respiratory syndrome (SARS)

·        Mouse hepatitis virus, strain A59 (MHV-A59)

UV disinfection systems provide a high rate of efficacy, although they are most effective in hospitals when used in addition to standard cleaning of hard surfaces and should never be considered a substitute for good cleaning practices.

Automatic UV Disinfection Systems for Hospitals

UV disinfection in hospitals is gaining traction due to the high rate of effectiveness and also because of the ability to automate the disinfection process. Many types of hospital UV disinfection systems are available such as:

·        Portable UVC robots and UVC light carts

·        Stationary solutions such as UVC lamps in light fixtures, overhead doors, and doorways

·        UVC lamps in HVAC systems disinfect the air

·        UVC lamps in water systems for clean water supply

With a wide range of UVC disinfection systems available to incorporate into hospitals and healthcare facilities, automating an effective UV disinfection solution is much more attainable than in previous years. Integrating UV disinfection systems with building management systems allows for facility managers to activate UV light disinfection systems on demand or as an automatic cycle in various areas of the hospital.

Automated hospital UV disinfection systems provide an invaluable benefit to protect patients and staff as well as cost-effective operation with no required labor. Activating automated UV disinfection in operating rooms after surgeries and prior to new patient arrivals adds a protective layer to manual cleaning and can reach odd places that may get overlooked during manual cleaning processes.

A study published by the National Institute of Health (NIH) in 2013, concluded that an automated hospital UVC system led to a significant decrease in the total number of colony-forming units (CFUs) of many types of organisms including Vancomycin-Resistant Enterococci (VRE), C. difficile and Acinetobacter.

Hospitals can incorporate automated UV disinfection systems in operating rooms, patient rooms, labs, storage facilities and on equipment surfaces. UVC germicidal lamps offer an enhancement to traditional cleaning methods and are proven to be more effective than cleaning with chemicals alone.

UVC Robot: Autonomous Virus Killer on Wheels

Originally posted at: https://www.light-sources.com/blog/uvc-robot-autonomous-virus-killer-on-wheels/

Ultraviolet radiation in the UVC range is known for killing viruses, bacteria, and harmful pathogens in many applications. You can find UVC germicidal lamps in disinfection systems worldwide used to kill viruses and bacteria in water, in the air, and on surfaces. UVC disinfection lamps are mounted in various disinfection systems, like water treatment plants, air purification systems, and industrial machines.

With advances in technology and robotics, UVC germicidal solutions are available in many forms of automatic UVC robots. These UVC robots can roam indoors and outdoors, killing viruses and bacteria almost instantly. UVC germicidal lamps are proven to kill most infectious microorganisms in seconds and eliminate difficult-to-treat pathogens like Methicillin-resistant Staphylococcus aureus (MRSA) or vancomycin-resistant enterococci (VRE) in minutes.

UVC Robots Beneficial in Many Environments

UVC robots are now popping up in many places such as hospitals, office buildings, shopping malls, libraries, and airports. Outdoor disinfection robots can be found on school campuses, industrial parks, and many other public gathering areas. These disinfection robots can be programmed to spray a disinfectant and also emit powerful UVC radiation at the precise wavelength of 254 nm, proven to have the most germicidal effectiveness.

The benefits of these autonomous robots are clear:

• No labor required – UV disinfection robots can disinfect a large area with no labor required. They can run for 24 hours continually and even head back to their charging station when needed.
• No infectious disease exposure to humans – while the robots are disinfecting an area, human employees such as nurses in hospitals are not exposed the superbugs that may be lingering in the room.
• Effective germ-killing ability – UVC robots are proven to eliminate most viruses and bacteria and even hard-to-treat pathogens which pose serious risks when exposed to humans.
• Safe when used without people in the room – UVC robots are set up to enter hospital rooms or other areas when vacant to avoid UV exposure to humans. They can be controlled remotely and programmed to shut down if movement is detected.

Proven Effectiveness of UVC Radiation in Hospital Rooms

According to a study in Infection Control & Hospital Epidemiology, UVC devices effectively eliminated bacteria on contaminated surfaces both in the line of sight and also behind objects. UVC radiation was 99.9% effective in reducing the counts of vegetative bacteria on surfaces within 15 minutes and was also proven 99.8% effective in reducing superbugs and C. difficile spores within 50 minutes.

UVC robots and UV germicidal devices are only as powerful as the quality of UVC germicidal lamps installed on the systems. Using high-quality UV germicidal lamps is key to achieving maximum germicidal effectiveness.

UV Kitchen Exhaust: Self-Cleaning Technology

Originally posted at: https://www.light-sources.com/blog/uv-kitchen-exhaust-self-cleaning-technology/

UV light technology provides disinfection solutions to a variety of air, surface, and water treatment applications with high-intensity UV lamps proven to break down organic compounds. UVC germicidal lamps are used in a multitude of environments where eliminating harmful microorganisms is critical, such as hospitals, schools, and many public areas including restaurants. UV lamps help to eliminate germs in the air and on surfaces, providing proven restaurant disinfection solutions in dining areas as well as in the kitchen with food irradiation and UV kitchen exhaust systems.

UV lamps in kitchen exhaust systems provide many benefits by preventing bacteria and grease buildup in kitchen exhaust hoods. This self-cleaning technology provides a cleaner, healthier and safer commercial kitchen by eliminating odors and mitigating the risk of grease fires.

UV lamps with emissions in the UVC wavelength have long been used in HVAC systems to eliminate bacteria and mold growth in ductwork. This UVC technology provides the same benefits and also prevents grease buildup in Commercial Kitchen Ventilation (CKV) systems.

How UV Kitchen Exhaust Systems Work

Kitchen exhaust systems provide the primary function of extracting grease through mechanical filters and inertial means. Kitchen hood exhausts successfully remove grease particles. The smaller grease particulates and vapor that remain are then exposed to the UVC light to break down the molecules. This process effectively prevents grease buildup, thus reducing maintenance, cleaning and mitigating fire hazard.

Photolysis and Ozonolysis

UVC lamps in UV kitchen exhaust systems break down grease particles in commercial kitchen exhaust systems through two distinct processes: photolysis and ozonolysis. Photolysis is the chemical reaction that occurs when a chemical compound is broken down by photons. Photolysis breaks down the molecular bond and grease particles and ozonolysis oxidizes the grease molecules.

Installing UV Lamps in Kitchen Exhaust Systems

UVC germicidal lamps can be installed in the interior of the hood exhaust plenum, in stainless steel fixtures against the top or back of the ductwork. UV lamps should be installed in kitchen exhaust systems with a separation of at least 10 cm to provide ample spacing for effective photolysis to occur.

Breakdown of Grease Buildup

The UV radiation reacts with the air pulled through the kitchen hood exhaust during the photolysis process, also called photodissociation, where the photons break down the oxygen molecules into oxygen atoms. The oxygen atoms combine with any remaining oxygen molecules to form ozone molecules, which react with the organic compounds in the grease.

This chemical reaction called ozonolysis, alters the grease organic compounds in the exhaust air to form easier-to-clean byproducts, specifically carbon dioxide and water vapor. Ozonolysis is proven to significantly reduce the buildup of grease deposits in both the grease exhaust duct and the hood exhaust system.

Benefits of UV Lamps in Kitchen Hood Exhaust Systems

Reducing grease buildup reduces the maintenance and cleaning required in a kitchen hood exhaust and also decreases the likelihood of grease fires occurring in the kitchen exhaust system. Ozone is known to eliminate foul odors in the air, thus ozonolysis helps to eliminate the odor that comes with built-up grease, which can occur quickly in busy commercial kitchens.

UV disinfection lamps in UV kitchen exhaust systems help restaurant owners to achieve many benefits including:

· Significantly reduce built-up grease in kitchen exhausts

· Eliminate foul orders from stale, built-up grease

· Mitigate the risk of fires in kitchen exhaust systems

· Save money on cleaning and maintenance expenses

· Supports sustainable heat recovery

While UVC technology is safe and chemical-free, direct exposure to skin and eyes should be avoided. Safety measures that turn off the UV lights when the kitchen exhaust is turned off protect kitchen personnel.

It is important to use reputable UVC germicidal lamps and hood exhaust systems to ensure the proper breakdown of molecules as well as ensure the safety of kitchen and restaurant workers. UVC systems should be installed in kitchen hood exhausts with several interlocks, ensuring that the UV lights will turn off when the exhaust system is off or when a filter is removed to protect against human exposure.

The Various Uses for UV Light

Originally posted at: https://www.light-sources.com/blog/the-various-uses-for-uv-light/

The uses for UV light include a broad range of applications in commercial, industrial, and healthcare settings. Ultraviolet (UV) light is separated into three basic categories of UVA, UVB, and UVC based on the nanometer or wavelength of UV emissions. UVC light is the shortest wavelength emitted by the sun and is mostly absorbed by the ozone layer.

· UVA light is between 315 to 400 nm

· UVB light is between 280 to 315 nm

· UVC light is between 100 to 280 nm
