PALSOO Plasma Sterilization: A Chemical-Free Resolution for Protected Decontamination

In the course of the pandemic, spraying a mist was one of many frequent options opted by native governments, particularly in Southeast Asia. “What” is being sprayed can range. Among the many record of chemical substances regularly sprayed are Bleach, Hydrogen peroxide, Alcohol, Peracetic Acid, or Chlorine Dioxide, for instance. Whereas they’ll obtain the purpose of eliminating the contaminants, they’ll additionally trigger some degree of toxicity and environmental impression. Even the procurement and storage of those merchandise might be problematic.

PALSOO (all caps) is a Korean firm proposing a intelligent, non-toxic, and sustainable approach to obtain the identical consequence utilizing solely water. The corporate makes use of Plasma Sterilization, which solely makes use of power and water to generate sterilizing plasma-activated water. No chemical merchandise are concerned. 

The Plasma reacts with water coming from the reservoir, creating a mix of Oxygen and Nitrogen ions, neutrals, and radicals (OH-, O3, H2O2, NO2-, NO3—and ONOOH) that may trigger contaminants like viruses and chemical pollution to degrade on the molecular degree. In the end, this response destroys the contaminants.

The bodily manifestation of this know-how is the brand new FRIRUS sprayer (first picture, photograph credit score: Aving Information), which may generate and spray Plasma-activated water utilizing electrical energy and water as an enter. Created with the apparent environmental advantages above, the machine stays eco-friendly even after its lifecycle is over: most of it’s made out of bio-degradable supplies. PALSOO is aiming for RE100.

Whereas decontamination by spraying has been highlighted throughout the pandemic, it’s used routinely in lots of nations. This plasma answer might even be used extra regularly, particularly in areas the place significantly weak individuals (infants, aged, injured) might be uncovered to illnesses. 

By activating a myst of water with Plasma, PALSOO creates an environment friendly approach to decontaminate with out introducing dangerous chemical merchandise. The plasma sterilization impact will decay over time, however an fascinating side-effect of this course of is that the nitrogen-based components left have a fertilizer impact.

How lengthy does the Plasma impact final? PALSOO’s CEO says, “it varies relying on the temperature and kind of plasma. If in a gaseous state, the lifespan is longer however shortens when transformed to activated water. It lengthens at decrease temperatures and shortens at larger temperatures. Sometimes, plasma-activated water has a lifespan of about quarter-hour at 25 levels Celsius, enough to kill micro organism and is healthier because it disappears rapidly, posing no hurt to people.”

This isn’t even bearing in mind that in occasions of disaster, among the chemical substances talked about above, decontaminant, might not even be accessible, because it typically occurred throughout the pandemic. Clearly, utilizing water may even get rid of the price of shopping for and storing such chemical merchandise. 

In a catastrophe scenario, the FRIRUS_24 might be deployed rapidly, with out having to answer on the provision of any chemical substances. Electrical energy mills are normally current and water is simpler to seek out. PALSOO will current its sprayer, know-how and imaginative and prescient at CES 2025 in Las Vegas.
