HEPA air scrubbers to comprehensively eliminate contaminants, including COVID-19, from the ambient air. The choice of an appropriate air purifier hinges on the dimensions of the area in which it will be deployed, with a crucial consideration being its capacity to manage the requisite airflow volume. 

 HEPA air scrubber Testing:

 

HEPA air scrubber testing is a rigorous process carried out by manufacturers to assess the efficiency, integrity, and overall performance of these filters. These evaluations are integral to the production workflow, ensuring the final product’s quality. However, an equally vital step involves testing  HEPA air scrubbers once they are installed.

Flow Rate Assessment:

Before delving into any specific evaluation, it’s essential to examine the flow rate through the HEPA air scrubber . The International Organization for Standardization (ISO) provides a framework for on-site HEPA air scrubber testing to detect leaks and validate the airflow volume. These standards offer some flexibility to accommodate variations between vendors and customers.

Aerosol Testing:

Aerosol testing involves the use of both cold and hot aerosols, as well as microspheres, to assess the installation of HEPA air scrubbers in clean room environments. Cold aerosols are generated from oil-based liquids. The test involves setting the concentration of test aerosols upstream of the filter, typically at concentrations of 10µg/l and 100µg/l. Lower concentrations are recommended to prevent blockage or bleed-through.

Leak Scanning:

To identify potential leaks, a probe is employed to scan the system. The probe’s size influences its effectiveness, with smaller probes generally providing better results than larger ones. Additionally, the scanning velocity plays a role in the accuracy of the scan.

In ,HEPA air scrubbers there is a gap between the filter and its housing, with the gasket situated at the rear. To detect leaks in the frame-to-housing connection, a probe is inserted to scan the area. When there is a gasket leak, particles disperse and fill the gap, leading the scanner to encounter a concentration of particles at a distance from the actual leak, as depicted in the image below. 

Identifying Filter Face Leaks

Detection of filter face leaks involves a methodical process employing a probe that systematically scans the entire face of a HEPA filter. The probe moves across the filter with overlapping strokes, proceeding at a controlled and uniform pace. This examination may necessitate multiple passes to precisely locate the source of a leak. To enhance accuracy, a baffle plate can be positioned over the filter face, helping distinguish between gasket leaks and face leaks. During this process, the sample probe remains just a fraction of an inch above the filter’s surface to ensure that no leaks go unnoticed.

Remedying Leaks

Manufacturers and the Institute of Environmental Sciences and Technology (IEST) provide established procedures for addressing leaks. The IEST offers recommendations aimed at preventing blockages or restrictions in the filter during the repair process. Following any repairs, it’s imperative to retest the system to verify the effectiveness of the patching and ensure the unimpeded flow of air.

  6. Monitoring and Control: Modern air scrubbers often include monitoring and control systems within the scrubbing chamber to regulate factors such as air flow, pressure, and the injection of scrubbing solutions or chemicals.

The efficiency and effectiveness of the scrubbing chamber are critical to the overall performance of the air scrubber. The design and technology employed within this chamber are tailored to the specific contaminants and pollutants that need to be treated, making it a central element in achieving air quality improvement and pollution control objectives.

What is Filtration System of an air scrubber ?

The filtration system of an air scrubber is a key part of the scrubber that is responsible for capturing and removing airborne particles, dust, and other contaminants from the incoming air. It typically consists of several components, including:

  1. Pre-Filters: Pre-filters are the first line of defense in the filtration system. They capture larger particles, such as dust and debris, before the air moves through to the main filter. These pre-filters help extend the lifespan of the primary filters and reduce the frequency of filter replacement.
  2. Primary Filters: The primary filters are designed to capture a wide range of particulate matter, including fine particles, allergens, and other contaminants. Common types of primary filters include high-efficiency particulate air (HEPA) filters, which are highly effective at trapping tiny particles.
  3. Activated Carbon Filters: In some air scrubbers, activated carbon filters are used to adsorb and remove odors, gases, and certain volatile organic compounds (VOCs) from the air. These filters contain activated carbon granules with a large surface area that can trap and hold various chemical compounds.
  4. Chemical Filters: For air scrubbers used in industrial settings, chemical filters may be employed to specifically target and remove particular gases or contaminants. These filters are designed with the specific pollutant in mind and may use chemical reactions to neutralize the gases.
  5. Final Filters: After passing through the primary and optional secondary filters, the air may go through final filters, which further ensure that any remaining particles and impurities are removed before the clean air is released from the scrubber.

The filtration system of an air scrubber is crucial for improving indoor air quality by removing particulate matter, allergens, and odors. The choice of filter types and their efficiency depend on the specific air quality concerns and the pollutants that need to be addressed.

What is Media Beds or Packing Material (for Wet Scrubbers)?

In wet scrubbers, media beds or packing materials are a key component used to facilitate the absorption, reaction, and removal of pollutants and contaminants from the air or gas stream. These materials are typically arranged in the scrubbing chamber of the wet scrubber, and they are wetted with a liquid solution, which is often water or a chemical reagent. The purpose of the media beds or packing material is to provide a large surface area for intimate contact between the polluted air and the scrubbing liquid, allowing for effective pollutant removal.

Here’s how media beds or packing material work in wet scrubbers:

  1. Intimate Contact: The contaminated air or gas stream enters the scrubbing chamber, where it comes into contact with the wetted media beds or packing material. This contact ensures that the pollutants are exposed to the scrubbing liquid.
  2. Absorption or Reaction: Depending on the type of wet scrubber and the pollutants involved, the wetted media beds or packing material can facilitate absorption, neutralization, or chemical reactions with the contaminants. For example, acidic gases like sulfur dioxide (SO2) can be absorbed in water, while certain chemical reagents may be used to neutralize other pollutants.

Additionally, safety precautions should be taken when handling UV-C lamps, as prolonged exposure to UV-C light can be harmful to skin and eyes.

What is Ionization of an air scrubber?

Ionization in the context of an air scrubber refers to a technology called “ionization air purification.” This technology is used to improve indoor air quality by releasing charged particles (ions) into the air. The ions produced in ionization air purifiers can have various effects on airborne contaminants, such as particles, bacteria, viruses, and odors. There are two main types of ionization technologies commonly used in air scrubbers:

  1. Negative Ionization (Anion Generators): Negative ion generators release negatively charged ions (anions) into the air. These ions attach to airborne particles, causing them to become negatively charged. This makes the particles more likely to attach to positively charged surfaces in the environment, such as walls, ceilings, or other surfaces, rather than remaining airborne. This process can help remove particles from the air and reduce dust and allergens.
  2. Positive Ionization (Cation Generators): Positive ion generators release positively charged ions (cations) into the air. These ions may react with airborne contaminants, such as viruses and bacteria, potentially neutralizing them or causing them to clump together. The effectiveness of positive ionization in air purification is a subject of ongoing research.

Ionization technology is often used in combination with other air purification methods, such as filtration and UV-C light, to enhance the overall performance of air scrubbers. It is important to note that while ionization can be effective at improving indoor air quality, the specific benefits and mechanisms can vary depending on the type of ionization and the design of the air scrubber.

Some air purification devices that incorporate ionization may be marketed as “ionizers” or “ionizing air purifiers.” It’s essential to understand the specific technology used and its effectiveness for the removal of contaminants in a given application.

In recent years, bipolar ionization has gained attention as a technology that can help neutralize airborne pathogens, such as viruses, by releasing both positive and negative ions into the air. It has been used in various indoor settings to reduce the risk of infectious disease transmission, especially in healthcare facilities, schools, and commercial buildings.

What is Ozone Generators of an air scrubber?

Ozone generators, when incorporated into an air scrubber, are devices that produce ozone (O3) as part of the air purification process. Ozone is a molecule composed of three oxygen atoms, and it has the ability to react with and neutralize various contaminants and odors in the air. Ozone is a powerful oxidizing agent and can be used to remove airborne pollutants and improve indoor air quality. However, the use of ozone generators in air purification is a topic of debate and regulatory oversight due to potential health concerns.

Here’s how ozone generators work in air scrubbers:

  1. Ozone Production: The ozone generator within the air scrubber produces ozone by passing oxygen (O2) molecules through an electrical discharge or ultraviolet (UV) light. This process converts some of the O2 molecules into ozone (O3).
  2. Oxidation: Ozone is a highly reactive molecule, and it readily reacts with a wide range of contaminants. When ozone is released into the air, it can oxidize and break down pollutants, including bacteria, viruses, mold, volatile organic compounds (VOCs), and odors.
  3. Air Cleaning: Ozone, being a gas, is dispersed into the air within the air scrubber. As it circulates through the air, ozone reacts with and neutralizes contaminants, reducing their concentration.
  4. Ozone Decomposition: Ozone is inherently unstable and eventually breaks down into oxygen molecules (O2) after reacting with contaminants. This leaves the air cleaner and free from the harmful contaminants.

Ozone generators have been used for many years in various applications, including commercial and industrial air purification, water treatment, and odor control. However, there are concerns regarding the safety of ozone, as high concentrations can irritate the respiratory system and potentially cause health problems. Ozone is a respiratory irritant and can be harmful to people with certain medical conditions.

Regulatory agencies, such as the U.S. Environmental Protection Agency (EPA), have set limits on ozone levels for indoor air to protect human health. Some regions and countries have restrictions or bans on the use of ozone generators in occupied indoor spaces.

While ozone can effectively remove contaminants, its use in air scrubbers and air purifiers is a topic of controversy. Consumers and facility managers should exercise caution and ensure that any ozone generator used in an air scrubber complies with safety regulations and does not produce ozone concentrations above acceptable levels for human health. Additionally, it’s important to consider alternative air purification technologies, such as HEPA filtration, UV-C light, and other methods, to achieve effective air cleaning without the potential risks associated with ozone.

What is Dry Scrubbers?

Dry scrubbers, also known as dry scrubber systems or dry flue gas desulfurization (FGD) systems, are air pollution control devices designed to remove sulfur dioxide (SO2) and other acidic pollutants from industrial gas streams, particularly in exhaust gases from fossil fuel combustion processes. Dry scrubbers are used to reduce emissions of harmful gases and to comply with environmental regulations.

Unlike wet scrubbers, which use a liquid solution to absorb and neutralize pollutants, dry scrubbers employ a solid sorbent or reactant to chemically react with and capture acidic gases. The core principle of dry scrubbers is to promote chemical reactions between the pollutant gases and the sorbent in a dry environment. The key components and processes of a dry scrubber system include:

  1. Inlet: The polluted gas stream, often containing sulfur dioxide (SO2) and other acidic gases, enters the dry scrubber through an inlet.
  2. Reaction Chamber: This is where the gas stream comes into contact with the solid sorbent or reactant. The sorbent may consist of various materials, such as limestone (calcium carbonate) or sodium bicarbonate. The acidic gases react with the sorbent to form solid byproducts.
  3. Contaminant Capture: In the reaction chamber, the pollutant gases react with the sorbent to form solid compounds, which are captured in the dry scrubber. For example, the reaction with limestone produces calcium sulfate (CaSO4) and carbon dioxide (CO2). The solids are typically collected in a particulate control device.
  4. Particulate Control (Optional): Some dry scrubbers incorporate a particulate control device to capture and remove any solid particles generated during the reaction.
  5. Outlet: The clean, treated air is directed to an outlet and is released into the environment or directed to the desired location.

Dry scrubbers offer several advantages, such as lower water usage compared to wet scrubbers and the ability to operate in a dry environment, which may be more suitable for certain industrial processes. However, the efficiency of dry scrubbers can be affected by factors such as gas temperature, the chemical reactivity of the sorbent, and the gas residence time in the reaction chamber.

Dry scrubbers are commonly used in industries like power generation, cement manufacturing, and waste incineration to control emissions of acidic gases, particularly sulfur dioxide. The choice of sorbent and system design depends on the specific pollutants and air quality goals of a given application.

What is Electrostatic Precipitators?

Electrostatic precipitators (ESP), also known as electrostatic air cleaners, are highly efficient air pollution control devices used to remove fine particulate matter (such as dust and smoke), aerosols, and some gaseous pollutants from industrial and commercial exhaust gases. They work based on the principles of electrostatic attraction and are widely employed in various applications to improve air quality and reduce emissions.

The core components and mechanisms of an electrostatic precipitator include:

  1. Ionization Section: In this section, the polluted air stream passes through a series of discharge electrodes, which are electrically charged. The discharge electrodes generate a corona discharge or an electrical discharge that releases electrons, forming negatively charged ions.
  2. Collection Section: After passing through the ionization section, the gas stream enters a collection section with a set of oppositely charged plates or tubes known as collector electrodes. These collector electrodes are positively charged and are located downstream from the discharge electrodes.
  3. Electrostatic Attraction: As the negatively charged ions from the ionization section travel through the gas stream toward the positively charged collector electrodes, they encounter and attach to particles and aerosols in the air. This process imparts a negative charge to the particles.
  4. Particle Collection: The negatively charged particles and aerosols are drawn toward and adhere to the positively charged collector electrodes due to electrostatic attraction. This causes the pollutants to become trapped on the collector surfaces.
  5. Rapping Mechanism (Optional): In some electrostatic precipitators, a rapping or vibration mechanism periodically dislodges the collected particles from the collector surfaces, allowing them to fall into a hopper for disposal.
  6. Outlet: The clean, treated air exits the electrostatic precipitator and is released into the environment or directed to the desired location.

The efficiency of electrostatic precipitators in removing particulate matter is high, and they are particularly effective at capturing fine particles that may be challenging for other air pollution control devices. These devices are commonly used in industries with high particulate emissions, such as power plants, cement manufacturing, pulp and paper mills, and metal processing facilities.

It’s important to note that while electrostatic precipitators are effective at removing particulate matter, they are less suitable for capturing gaseous pollutants. In some cases, a combination of electrostatic precipitators with other air pollution control technologies, such as wet scrubbers, may be used to achieve comprehensive emission control. Proper maintenance and periodic cleaning of the collector electrodes are essential to ensure the continued efficiency of electrostatic precipitators.

What is Gas Absorption Scrubbers?
