Technology
Controlled cold plasma. Application-specific chemistry.
The process creates reactive chemistry from simple inputs. The engineering challenge is controlling that chemistry precisely enough to be useful — reliably, safely and economically.
Cold plasma
An electrically driven state — also called non-thermal plasma — in which electrons are highly energetic while the bulk gas stays near ambient temperature. This makes it possible to drive chemical reactions without heating the whole system.
Gas–water interaction
Reactive species formed in the cold plasma are brought into contact with water. Reactor geometry, flow and contact time determine which species dissolve and in what proportion.
Process control
Power, gas composition, water properties and residence time are tuned to the target application. Clean and Grow use different settings and aim for different chemistry.
Air pathways · N₂ and O₂
Air is not one input. It is two.
Air is mainly nitrogen (N₂) and oxygen (O₂). Depending on the application, the process can activate air as a whole — letting nitrogen and oxygen react together — or guide nitrogen and oxygen along separate pathways for more selective chemistry.
Joint pathway
Air (N₂ + O₂) → cold plasma → combined reactive species
Nitrogen and oxygen are activated together, for example to form the nitrogen oxides that become nitrate in water.
Separate pathways
N₂ and O₂ → individually controlled activation
Nitrogen and oxygen streams are handled separately to steer which reactive species form and in what proportion.
Which configuration suits a given application is part of our development and validation work.
Nitriva Systems
The equipment and integration platform.
Nitriva Systems covers the reactors, power electronics, controls and interfaces that make cold plasma processes usable in real operations. The goal is equipment that fits customer processes: robust, monitorable and serviceable.
FAQ
Common questions.
What is cold plasma-activated water?
Water that has been exposed to reactive species generated from air by cold plasma. The exposure changes its chemical properties, for example its acidity and the presence of reactive oxygen and nitrogen compounds. The exact composition depends on the process.
How do Clean and Grow differ?
Clean targets short-lived reactive chemistry relevant to sanitation. Grow targets stable nitrate as a plant nitrogen source. They share underlying cold plasma know-how but use different process conditions, equipment configurations and validation criteria.
Can activated water be stored?
It depends. Some reactive species are short-lived, while nitrate is comparatively stable. Storage behaviour is a core part of our validation, which is one reason we focus on on-site, on-demand production.
What determines energy consumption?
Mainly the target chemistry, the required concentration, reactor efficiency and how well gas and water are brought together. We will report energy figures only once they are measured under representative conditions.
How can a pilot be evaluated?
By agreeing up front on the problem, the baseline, success criteria and measurement methods. A pilot then compares results against the current process, including performance, operating cost, material effects and practical integration.
