The utilization of photocatalytic oxidation for cleaning air and water is an innovative and emerging technology. This purification technique has been commercialized by numerous companies and extensively studied by researchers. Experience the excitement of this cutting-edge technology. PECO VS PCO Technology in Air Purifiers?
Cutting-edge technologies are revolutionizing the way we tackle pollution. Inventive devices, such as photoreactors, work by harnessing the power of light to combat harmful pollutants in both air and water. Photocatalytic Oxidation (PCO) and Photo Electrochemical Oxidation (PECO) are two popular types of photo reactor based air purifiers that are transforming the air purification industry. Air purifiers by triadaer are based on PCO technology that are very popular in the USA.
One such innovative device that employs proprietary PECO technology is the Molecule air purifier, which offers superior air purification capabilities for your home or office. Discover What Makes the PECO Air Purifier Stand Out from the Competition with Our Comparative Breakdown?
What is Photocatalytic Oxidation?
Discover the effective process of photocatalytic oxidation purification. Through the power of light-activated catalysts, organic pollutants are transformed into non-toxic substances, providing a pure and safe environment. Witness the chemical reaction that leads to a cleaner future.
In recent decades, the concept of utilizing a revolutionary process to purify the air and water of harmful contaminants has gained significant attention. As this technology increasingly becomes mainstream, more and more companies are introducing products with this capability, sparking widespread interest.
Differences Between The Photocatalytic Process Used In PECO and PCO Air Purifiers.
In what way does PECO differ from PCO?
Molekule air purifiers utilize an advanced air purification process known as Photo Electrochemical Oxidation (PECO). This cutting-edge technology is built upon photon-based techniques and surpasses traditional Photocatalytic Oxidation (PCO) air purifiers in both speed and efficiency. PECO is currently the leading commercial technology for purifying the air.
Both PCO and PECO rely on high energy photons to trigger a series of reactions by releasing negatively charged electrons and creating positively charged holes. Unfortunately, in a PCO process, the electrons and holes tend to combine, meaning there are fewer available holes for reactions. As a result, the process can be quite inefficient.
PECO technology excels at separating electrons and holes resulting in unparalleled reaction speed and efficiency without any undesirable byproducts. However, Essentially, PECO achieves complete oxidation of organic pollutants in the air by utilizing light photons to their maximum potential.
The following are the essential components required for any photocatalytic process:
Photocatalyst
Discover how photocatalysts can help purify the air in your home. By activating a chemical reaction on their surface when exposed to light, these substances effectively break down pollutants. Also, Learn how PECO and PCO air purifiers utilize this technology to eradicate harmful particles.
With over two decades of engineering, PECO’s proprietary catalyst has been optimized for maximum efficiency. Breathe easy with cleaner, fresher air.
A photocatalyst is an agent that triggers a chemical reaction when subjected to light. In the field of air purification, both PECO and PCO devices rely on this phenomenon to eliminate contaminants. Also, PECO employs an exclusive catalyst that has undergone extensive development for over 20 years, guaranteeing the highest level of effectiveness in the process.
Free Radicals and Reactive Oxygen Species
Photoreactor processes employ light photons to release electrons from the catalyst’s surface, creating positive holes where electrons once resided. Hydroxyl ions (-OH) are naturally formed from water vapor, carrying a negative charge. These ions interact with the positive holes on the catalyst surface by filling in the hole with an electron, thus restoring the electric neutrality of the ions and creating hydroxyl free radicals.
Hydroxyl free radicals are incredibly powerful oxidizers that can break down even the most resilient organic molecules, thanks to oxygen from the air. Also, This process typically transforms organic compounds into carbon dioxide, water, and other trace gasses, without the need for intense heat, akin to incineration.
The PECO process stands out as it binds free electrons and separates them from positive holes, allowing for the formation of hydroxyl free radicals. This crucial difference has significant consequences in comparison to the PCO process that can only use a small portion of photons, making it overall inefficient. As a result, incomplete reactions in some systems could lead to toxic oxidation byproducts like formaldehyde, posing potential dangers.
Safety And Effectiveness Differences Between PECO and PCO Air Purifiers.
Efficiency is key when it comes to photocatalytic air purifiers. That’s why engineers carefully consider a variety of factors that impact the performance of a PCO device. These include the levels of light exposure, the concentration and types of pollutants the device must remove, air flow rates; moisture levels, and factors specific to the catalyst used.
By optimizing these factors, engineers can create a more effective and safe air purifying solution; like the Molekule air purifier, which has undergone rigorous testing in a laboratory setting.
To determine if a PCO system is both safe and effective, there are several methods that a consumer can utilize.
No Ozone
To comply with California’s safety standards, only air purifiers that meet CARB’s regulations can be sold in the state. Check both the CARB and manufacturer’s website to ensure that the PCO system is CARB compliant. The good news is that the Molekule PECO air purifier has earned this certification; and undergone independent testing by Intertek Laboratories to confirm that it produces absolutely no ozone.
Significant Amount Of Research
When choosing a photocatalytic air purifier, it’s crucial to assess its ability to eliminate pollutants such as VOCs and microbes. Seek out studies conducted by independent laboratory companies to gauge its effectiveness. Absence of research suggests the unit is either inefficient or ineffective.
