Nanobubbles, less than a thousand nanometers in size, imperceptible to the human eye, are currently the most efficient system for transporting gases, remaining for days or weeks in a liquid medium, allowing fungi and bacteria to be effectively sanitized. This particularity was put to the test by Camanchaca and the Chilean start-up Kran, specifically at the San José Primary Plant, located in the commune of Calbuco.

Through a press release, the salmon farming company reported that the innovative technology was successfully piloted in the plant, resulting in a 70% reduction in the use of disinfectant in the chiller and a 50% reduction in the use of detergents used in the foaming process, with which the surfaces of the equipment are cleaned.

Thanks to these results, Camanchaca opted for its implementation, becoming the first salmon farming company in Chile to integrate a nanobubble system for its hygiene processes.

In this regard, Ignacio Coronado, Head of Industrial Projects at Kran, explained that “these bubbles increase the efficiency of detergents and disinfectants, which leads to a more effective removal of contaminants and microorganisms on various surfaces, being the main objective for both companies in this R+D project, so we are proud of the results obtained and the trust in us”.

The nanobubbles, composed of a mixture of different gases, manage to enter different porosities, allowing detergents or sanitizers to be applied on smaller surfaces, improving their drag and permanence over time. This offers an effective and sustainable solution, as it reduces the amount of water and chemicals used, without affecting the high quality standards thanks to the results evidenced in the microbiological controls carried out on a daily basis.

In line with the above, Karol Baron, Deputy Manager of Salmones Camanchaca Processes, stressed that “this project is aligned with our sustainable objectives and goals, seeking not only better environmental practices, but also contributing to the development of new local solutions that can be replicable and scalable both for the aquaculture industry and in others, which is why we are already implementing it in our facilities on a constant basis”.

Kran’s nanobubble project thus solves critical water challenges and revolutionizes key industrial processes in salmon farming, agriculture and water treatment, contributing to the commitment of both companies in the search for more environmentally friendly practices, delivering sustainable, efficient and profitable alternatives.
