WHAT IS PAW?
From plasma generation to the principles of activated water — step by step.
Plasma is a state of matter. Matter exists in four fundamental states, and plasma is the highest-energy of them.
Plasma is all around us — in nature and in everyday technology.

PLASMA ACTIVATED WATER
PAW stands for Plasma Activated Water.
When water meets plasma-treated air, its chemical composition changes and new reactivity is formed.
REACTIVE OXYGEN · ROS
Attack the cell walls and membranes of microorganisms
Radicals like •OH act within seconds, while hydrogen peroxide lasts much longer and carries much of the antimicrobial power during storage.
REACTIVE NITROGEN · RNS
Lower pH and can act as plant nutrients
Nitrite and nitrate are long-lived. They make the water acidic and, at low concentrations, act as fertiliser for seeds and crops.
REPRESENTATIVE RESEARCH VALUES — REACTIVITY IS TUNED BY GAS, POWER & TREATMENT TIME
Plasma activation induces measurable changes in water chemistry.
Activation lowers pH, making the water mildly acidic.
Increased oxidizing power strengthens disinfection and cleaning.
Reactive oxygen and nitrogen species (RONS) drive the functionality.
Higher ion concentration increases electrical conductivity.
Plasma-activated water is an emerging technology, with roughly fifteen years of active research behind it. Its appeal is that it's made on site from air, water and electricity, leaving no synthetic chemical residue.
Because the most powerful reactive species are transient, PAW is usually produced on demand rather than shipped or stored for long. Disinfection and agricultural uses are the most established; biomedical applications are genuinely promising but remain under study. It is a treatment liquid, not a health beverage.
