PALSOO Plasma Sterilization: A Chemical-Free Resolution for Secure 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 fluctuate. Among the many record of chemical substances continuously 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 stage of toxicity and environmental influence. 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 solution 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. In the end, this response destroys the contaminants.

The bodily manifestation of this expertise 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 plain environmental advantages above, the gadget stays eco-friendly even after its lifecycle is over: most of it’s produced from 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 international locations. This plasma resolution might even be used extra continuously, particularly in places 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 solution 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 increased temperatures. Sometimes, 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 shortly, posing no hurt to people.”

This isn’t even considering that in occasions of disaster, a number of the chemical substances talked about above, decontaminant, might not even be obtainable, because it generally 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 state of affairs, the FRIRUS_24 could possibly be deployed shortly, with out having to answer on the provision of any chemical substances. Electrical energy turbines are often current and water is simpler to seek out. PALSOO will current its sprayer, expertise and imaginative and prescient at CES 2025 in Las Vegas.
