Clean Air Using Bipolar Ionization and Ultraviolet Irradiation

Breathing clean air is essential for living and maintaining a healthy life. Indoor air quality is easy to forget about, although many of us spend the majority of our time inside. Whether it’s an office building or a healthcare facility, air quality is important. The conversation around indoor air purification has intensified in recent years due to COVID-19. Two effective ways of cleaning indoor air are bipolar ionization and ultraviolet irradiation in your HVAC systems.

Bipolar Ionization

Bipolar Ionization, or BPI, converts oxygen molecules to charged ions using electric voltage. These charged ions are effective against viruses, bacteria, and mold. The ions attach to contaminants and make them large enough for HVAC system filters to capture them. Some contaminants become heavy enough to fall onto surfaces that are easier to clean.
ions created for bipolar ionization to clean air

BPI also removes organic compounds, odors, and allergy-causing dangers. Bipolar Ionization doesn’t replace MERV air filtration but helps boost the filtration system.

Ultraviolet Irradiation

Ultraviolet light is one of several types of light that exist within the entire light spectrum. UV lamps have long been used to control infectious microorganisms in medical facilities. A UV-C fluorescent lamp generates light that can inactivate mold, bacteria, and viruses.
Light spectrum ranging from infrared to ultraviolet

Ultraviolet HVAC systems come in two main categories: air sterilization and coil sterilization. Air Sterilization is an in-duct system. It disinfects the air as it moves through the ducts of an HVAC system.  Coil Sterilization is a more targeted approach to zapping air pollutants. UV HVAC devices are placed near high-risk components such as condensation pans to keep them clean.

Clean Indoor Air Using HVAC Systems

Both bipolar ionization and ultraviolet irradiation are effective ways to ensure the air you’re breathing is clean and healthy. Keeping indoor air free of contaminants starts with your HVAC system. If you’re considering one of these options for an upcoming project or can’t decide between the two, contact the experts at ColonialWebb. The trusted experts at ColonialWebb will advise you on the best system for your big project!

Biofilm in HVAC Systems

Indoor air quality is critical for maintaining a healthy and safe environment for building occupants. Unfortunately, pollutants, allergens, and microorganisms such as bacteria, viruses, and mold can contaminate indoor air, leading to various health issues. Ultraviolet Germicidal Irradiation (UVGI) is a technology that uses ultraviolet (UV) light to inactivate and destroy microorganisms, preventing them from becoming biological hazards.


Biofilm in HVAC Systems

Biofilm is a complex microbial matrix of mold and bacteria that grows on the fins of the HVAC system’s evaporator coils, drain pans, and ducts. What appears as dirt, slime, or sludge on the surfaces of these components is, in fact, biofilm. Biofilm can also grow on other surfaces where moisture and nutrients are present. The presence of biofilm in HVAC systems can create serious health hazards for building occupants.

Numerous studies have demonstrated that improper maintenance of HVAC systems can contribute to the growth and dissemination of pathogenic, opportunistic bacteria, viruses, and mold. Biofilms give off products of metabolism known as volatile organic compounds (VOCs), which can trigger occupant complaints of watery eyes, headaches, and even severe allergy and asthma responses. In some extreme cases, biofilms can lead to Sick Building Syndrome (SBS), a condition in which occupants experience symptoms related to a particular building.

The quality of indoor air is influenced by the levels of bioaerosols, contaminants, and pollutants, which can significantly impact occupant health and development. Therefore, it is essential to take steps to prevent biofilm growth in HVAC systems and improve indoor air quality.


UVGI Technology to Prevent Biofilm Growth

Ultraviolet Germicidal Irradiation (UVGI) technology has proven to be a highly effective means of preventing the growth of biofilms in HVAC systems. UVGI uses ultraviolet energy to inactivate and destroy microorganisms, including bacteria and viruses, by altering their DNA and preventing reproduction. UVGI’s germicidal effect is strongest when using UVC energy, which has a 200 to 280 nanometers wavelength.

UVGI technology can be applied to HVAC systems in several ways, including using ultraviolet germicidal lamps. These lamps emit a concentrated radiation of ultraviolet energy that destroys microorganisms on contact. Installing UVGI lamps in an HVAC system requires air handlers and duct system modifications to accommodate the lamps. The process also requires new power to feed each lamp.


ColonialWebb and Chesterfield Country School Systems

ColonialWebb’s Special Projects MEP team partnered with Chesterfield County School Systems to install UVGI systems in 15 schools. The installation process involved modifying the HVAC air handlers and duct systems to accommodate the UV lamps.
