Industry Insights
At Depurex, we are experts in photocatalytic filtration, but our mission is clean air for everyone. Our blog features insights on a wide range of filtering technologies and environmental pollutants, even those not directly addressed by photocatalysis.
If you are a professional looking to share your academic or professional expertise, we would be delighted to host your articles.
Photocatalytic Filtration in the Agri-Food Sector: Extending Shelf Life, Odor Abatement, and Sanitization
Photocatalytic filtration represents an advanced air purification technology based on the use of light-activated titanium dioxide (TiO₂), capable of degrading volatile organic compounds (VOCs), odorous molecules, and contaminating agents through oxidative reactions that transform undesirable substances into harmless products.
Limitations of activated carbon in VOC treatment: saturation, channeling, and the photocatalytic alternative
Traditional activated carbon filters present three structural criticalities in VOC treatment: channeling (preferential flows that bypass parts of the filter bed) and the progressive saturation of the adsorbent material
Comparison of Formaldehyde Abatement Technologies: The Innovation of Photocatalysis
Technical guide to industrial formaldehyde abatement: a comparative analysis between Regenerative Thermal Oxidation (RTO), Scrubbing, Biotrickling, and innovative TiO₂ Photocatalytic Filtration. Discover how to ensure compliance with EU VOC directives.
Understanding volatile organic compounds
In termini semplici, un Composto Organico Volatile (COV) è una sostanza chimica a base di carbonio che evapora facilmente a temperatura ambiente, trasformandosi in gas o vapore. A causa della
Mlab Cusing 200R: How to halve your filtering costs
How to reduce costs for filter parts on a GE Additive's Mlab Cusing 200R 3D printer
Reducing solvent emissions in paper packaging: a look at the PUSTERLA 1880 project
Case Study of a solvent abatement plant with titanium dioxide photocatalytic filters installed at a cartographic industry of European significance.
odor abatement: types and methods
Odor abatement is the process of reducing or eliminating unpleasant odors from an environment.
The perception of a bad odor should not be underestimated because it may not be solely concerned with the appearance
Air sanitization: the bactericidal power of titanium dioxide
Photocatalysis has been shown to kill a wide range of organisms, including gram-negative and gram-positive bacteria, including endospores, fungi, algae, protozoa, and viruses, as well as
Indoor Air Pollution: A Growing Concern
Indoor air pollution (or SBS – Sick Building Syndrome) is often more dangerous than outdoor pollution because we spend 90% of our time indoors, where VOCs accumulate. The air we breathe inside offices and industrial facilities can be up to five times more polluted than outdoor air. This is due to specific contaminant sources that add to atmospheric smog, including emissions from paints and furniture, mold growth, humidity, and the use of chemical detergents.
Effectiveness of photocatalytic filtration against viruses and coronaviruses
Photocatalytic filtration is not only intended for the abatement of volatile organic compounds and odors, but is remarkably effective in the abatement of bacteria and viruses (especially in conjunction with a source
Fabric softener: a toxic source?
Even a product that gives us pleasant and positive feelings like fabric softener, with its scent of "good" and "clean," is a source of toxic substances including volatile organic compounds.
Air Sanitization:
Photocatalysis plus UVC
This article by the Don Gnocchi Foundation, "Coronavirus, high germicidal power of ultraviolet rays demonstrated," takes stock of research findings on the subject.
