Air Purification: Challenges and Solutions for Industrial Environments
Particles, microorganisms, and volatile chemical compounds are all invisible contaminants that compromise the health of workers and the quality of products. There are severalair purification techniques that can reduce these pollutants.
These processes are also referred to as air purification, filtration, or air decontamination—all of which refer to the same objectives. In industrial environments, where the volumes of air to be treated are large and technical constraints are numerous, this issue requires solutions that differ from those offered to the general public.
Who is affected by the sanitation of business premises?
First and foremost, industries subject to strict health and safety requirements are seeking to install high-performance air purifiers.
The healthcare sector—operating rooms, laboratories, and healthcare facilities—requires strictly controlled air quality to protect patients and healthcare workers.
The pharmaceutical industry is also on the front lines, as even the slightest microbiological contamination can render a batch unusable and result in liability for the manufacturer.
The food industry faces the same requirements, with strict regulations governing facility hygiene and food safety.
Other industries, which may not seem obvious at first glance, are also affected. The wine industry, for example, is particularly susceptible to fungal contamination and, above all, chemical contamination from TCA and TeCA, which can spoil products in the cellar.
Finally, the service sector—offices, data centers, and public-facing facilities—is increasingly seeking to improve indoor air quality, particularly in the wake of recent health crises.
Air purification is much more than just a matter of comfort; it is a regulatory and economic requirement for industry players.
What are the specific risks associated with poor air quality in an industrial facility?
Untreated air in a production environment exposes the company to three types of risks.
Airborne Particles
This dust settles on surfaces, equipment, and products. Furthermore, microorganisms use these particles as carriers. In a food industry facility or a pharmaceutical cleanroom, this contamination can lead to non-compliance, resulting in the rejection of the entire batch. The larger the volumes processed, the more significant the economic impact.
Microbiological contamination
This is the most insidious risk. Bacteria, mold, and yeast spread through the air in work areas and colonize surfaces, raw materials, and finished products. The consequences range from product spoilage to a real health risk for workers and consumers.
Chemical Pollution
Volatile organic compounds (VOCs), which originate from solvents, industrial processes, or building materials, can contaminate products and gradually poison people present on the premises. Employee exposure to VOCs may result in the employer being held liable under occupational hazard prevention regulations.
For the company, the consequences are tangible: regulatory noncompliance, production losses, risks to employee health, damage to its reputation, and more. Air decontamination is therefore essential.
How can we purify the air in workplaces, and what are the limitations of the techniques used?
There are several approaches to treating the air in work environments. Each has its own advantages and limitations.
Particulate Filtration
This is a mechanical filtration process: air passes through filters that trap airborne particles based on their size. This technique is effective for dust, but causes a significant pressure drop in ductwork systems, which can increase energy consumption. Furthermore, it does not treat gaseous contaminants or microorganisms.
Molecular Sanitation
This technique is designed to remove chemical pollutants (gases, vapors, VOCs) as well as unpleasant odors using adsorbent media or oxidation processes. Essential in certain environments, it often complements a microbiological approach.
Misting and Fumigation
These two methods decontaminate surfaces and the air by dispersing biocidal products. While they are truly effective, they come with a major limitation: they cannot be used in the presence of people. Furthermore, these sanitization techniques do not provide continuous protection. They are therefore suitable for one-time, scheduled cleaning operations, not for permanent air treatment.
Continuousmicrobiological air purification is now a major challenge for sensitive sectors. The challenge lies in continuously neutralizing microorganisms present in the air inside facilities without interrupting operations.
Why choose Photoclean to meet your industrial air decontamination needs?
We offer a comprehensive solution designed to address the realities on the ground in industrial and commercial environments.
Our technology is based on UV-C photolysis, combined with a proprietary filter medium manufactured in-house. This process continuously destroys microorganisms—bacteria, viruses, mold, and yeast. This approach is effective on very large volumes of air and results in low pressure drop, which minimizes energy consumption. Our standalone units also incorporate particulate-
e filters, providing dual particulate and microbiological efficiency.
How are our air treatment modules installed?
Our filtration units are compatible with most existing ventilation systems. As for our air decontamination modules, they integrate directly into existing air handling units (AHUs) and ductwork systems without requiring major construction work.
Photoclean has an in-house engineering department that:
- conducts an audit of the premises
- analyzes sources of contamination
- offers a layout plan tailored to the building’s configuration
Our customized solutions minimize dead zones, where air stagnates and pollutants accumulate.
Photoclean tailors its solution to the actual risk level at each site. For demanding environments, we offer comprehensive microbiological decontamination. In spaces that require partial control of contaminants, such as cleanrooms, our modules provide basic air filtration. Our solution also treats chemical pollutants for microbiological and molecular air purification.
This provides you with a threefold benefit:
- sustained air quality throughout the building
- Protection for teams and products on a daily basis
- energy efficiency management
Photoclean doesn’t offer a one-size-fits-all product, but rather a customized solution tailored to the specific requirements of each facility. Would you like to improve the air quality in your facilities? Contact Photoclean for a personalized assessment.
