Process intensification plays a vital role in modern manufacturing. One key process, known as cavitation, effectively homogenizes and mixes particles in liquids.
Our NANOCAV technology offers diverse applications, including efficient de-aeration of viscous fluids and the creation of stable emulsions. In anaerobic wastewater treatment, it aids in breaking down pollutants and organic molecules while increasing biogas production. Catalyst cleaning is an area yet to be fully explored.
NANOCAV, utilizing NanO-Cavitation Technology, is a process intensification technique for the manufacturing industry. Its flow reactor design is a unique innovation in process engineering, enabling cost-effective and highly adjustable continuous-flow nanO-Cavitation processes for both physical and chemical reactions in liquid environments.
Process Operation
The concept evolved from a conventional single-channel flow reactor used in emulsification processors or cavitation cell disruptors. It achieves a balanced exposure to the entire reaction medium, creating a cavitating effect and releasing local energy spurts in the liquid mass. This, in turn, increases the reaction rate based on the reaction kinetics.
The system pumps the reaction mixture into a lower holding chamber, where it receives even exposure to high-energy nanO-Cavitation through multiple parallel channels. The processed reactants then flow upward to the upper holding chamber through the outlet nozzle. This entire operation can be conducted in a gas-tight sealed environment.
