PALSOO Plasma Sterilization: A Chemical-Free Answer for Secure Decontamination

In the course of the pandemic, spraying a mist was one of many widespread options opted by native governments, particularly in Southeast Asia. “What” is being sprayed can differ. Among the many listing of chemical compounds ceaselessly sprayed are Bleach, Hydrogen peroxide, Alcohol, Peracetic Acid, or Chlorine Dioxide, for instance. Whereas they will obtain the aim of eliminating the contaminants, they will additionally trigger some stage of toxicity and environmental impression. Even the procurement and storage of those merchandise could 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 can trigger contaminants like viruses and chemical pollution to degrade on the molecular stage. Finally, 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 might generate and spray Plasma-activated water utilizing electrical energy and water as an enter. Created with the plain 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 in the course of the pandemic, it’s used routinely in lots of nations. This plasma answer may even be used extra ceaselessly, particularly in areas the place significantly susceptible individuals (infants, aged, injured) could possibly be uncovered to ailments. 

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 attention-grabbing 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 increased temperatures. Sometimes, plasma-activated water has a lifespan of about quarter-hour at 25 levels Celsius, adequate to kill micro organism and is best because it disappears rapidly, posing no hurt to people.”

This isn’t even bearing in mind that in instances of disaster, a number of the chemical compounds talked about above, decontaminant, might not even be obtainable, because it typically occurred in the course of the pandemic. Clearly, utilizing water can even remove the price of shopping for and storing such chemical merchandise. 

In a catastrophe scenario, the FRIRUS_24 could possibly be deployed rapidly, with out having to answer on the supply of any chemical compounds. Electrical energy turbines are often current and water is less complicated to search out. PALSOO will current its sprayer, know-how and imaginative and prescient at CES 2025 in Las Vegas.
