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

Throughout 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 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 affect. Even the procurement and storage of those merchandise may be problematic.

PALSOO (all caps) is a Korean firm proposing a intelligent, non-toxic, and sustainable approach to obtain the identical outcome 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 stage. Finally, this response destroys the contaminants.

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

Whereas decontamination by spraying has been highlighted through the pandemic, it’s used routinely in lots of nations. This plasma answer might even be used extra ceaselessly, particularly in places the place notably susceptible folks (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 attention-grabbing side-effect of this course of is that the nitrogen-based parts left have a fertilizer impact.

How lengthy does the Plasma impact final? PALSOO’s CEO says, “it varies relying on the temperature and sort 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 greater temperatures. Usually, plasma-activated water has a lifespan of about quarter-hour at 25 levels Celsius, ample to kill micro organism and is healthier because it disappears rapidly, posing no hurt to people.”

This isn’t even making an allowance for that in instances of disaster, among the chemical compounds talked about above, decontaminant, might not even be out there, because it generally occurred through the pandemic. Clearly, utilizing water may even eradicate 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 compounds. Electrical energy turbines 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.
