In the course of the epidemic, spraying fog is among the options generally chosen by native governments, particularly in Southeast Asia. The “content material” of the spray could fluctuate. Generally sprayed chemical substances embrace bleach, hydrogen peroxide, alcohol, peracetic acid or chlorine dioxide. Whereas they will obtain the objective of eliminating pollution, additionally they trigger a degree of toxicity and environmental influence. Even the sourcing and storage of those merchandise may be problematic.
PALSOO (all caps) is a Korean firm that has give you an ingenious, non-toxic and sustainable strategy to obtain the identical outcomes utilizing simply water. The corporate makes use of plasma sterilization know-how, utilizing solely power and water to supply sterile plasma-activated water. No chemical merchandise concerned.
Plasma reacts with water from the reservoir to supply a mixture of oxygen and nitrogen ions, impartial ions and free radicals (OH-, O3, H2O2, NO2-, NO3 – and ONOOH), which may trigger viruses and chemical contaminants, and so forth. Pollution are degraded on the molecular degree. Finally, this response destroys the contaminants.
The bodily manifestation of this know-how is the brand new FRIRUS sprayer (first picture, credit score: Aving Information), which may generate and spray plasma-activated water utilizing electrical energy and water as inputs. The machine has the apparent environmental advantages talked about above and stays environmentally pleasant even after its life cycle is over: it’s principally made from biodegradable supplies. The objective of PALSOO is RE100.
Whereas spray decontamination has been emphasised throughout the pandemic, it’s already used routinely in lots of international locations. This plasma resolution may very well be used much more continuously, particularly the place significantly susceptible teams of individuals (infants, the aged, injured) could also be uncovered to illness.
By the key of activating water with plasma, PALSOO has created an efficient methodology of purification with out the introduction of dangerous chemical merchandise. Plasma sterilization results decay over time, however an fascinating aspect impact of this course of is that the nitrogen-based components left behind act as fertilizer.
How lengthy does the plasma impact final? The CEO of PALSOO stated: “It modifications relying on the temperature and sort of plasma. Whether it is within the gaseous state, the life is longer, however when transformed into energetic water, the life is shortened. It elongates at decrease temperatures and at larger temperatures. Temperature shortens. Beneath regular circumstances, the service lifetime of plasma activated water is about quarter-hour at 25 levels Celsius, which is sufficient to kill micro organism and disappears rapidly with out inflicting hurt to the human physique.
This doesn’t even consider that in instances of disaster, among the above chemical substances (stain removers) could not even be obtainable, as has generally occurred throughout the pandemic. Clearly, utilizing water can even get rid of the price of buying and storing such chemical merchandise.
In a catastrophe state of affairs, FRIRUS_24 may be deployed rapidly with out counting on the supply of any chemical substances. There are normally turbines and water is simpler to search out. PALSOO will showcase its sprayers, know-how and imaginative and prescient at CES 2025 in Las Vegas.
