Nanobubble technology specialist Moleaer and Chilean firm Semarco have announced a partnership aimed at improving seabed remediation in the country’s salmon farming sector.
The collaboration will see nanobubble technology incorporated into remediation work, with the companies stating that it can accelerate natural recovery processes in seabed sediments while improving efficiency. Chile’s salmon industry operates under strict environmental rules, particularly around the condition of the seabed beneath farm sites.
According to the companies, early field trials indicate that remediation timelines and costs associated with the process could be reduced by around 20-30% compared with conventional methods. These results, the companies explain, are due to increased oxygen levels in affected sediments, which help speed up the breakdown of organic material through biological and chemical processes.
“Chile’s salmon industry has demonstrated a strong commitment to responsible environmental stewardship,” said Warren Russell, Chief Commercial Officer at Moleaer, via a joint press release. “Our collaboration with Semarco demonstrates that environmental performance and operational efficiency can advance together. By combining Moleaer’s proven nanobubble solutions with local remediation expertise, we can help producers restore seabed conditions faster while improving the economics of remediation.”
The technology works by increasing oxygen availability in targeted seabed areas, supporting faster biological recovery of sediments. The companies claim this can lead to shorter intervention times, lower fuel use in maritime operations, and more efficient remediation overall.
“Seabed remediation is a critical component of maintaining responsible aquaculture operations in Chile,” said Christian Fuentes of Semarco. “By integrating Moleaer’s technology with our operational capabilities in maritime and environmental services, we can accelerate natural recovery processes in impacted sediments while improving the efficiency of remediation work carried out for producers.”
Semarco operates in southern Chile, including the Los Lagos, Aysén and Magallanes regions, and is authorised by Subpesca, the country’s fisheries and aquaculture regulator, to carry out remediation work. Its team includes engineers, marine biologists and environmental specialists working with salmon producers.
Meanwhile, Moleaer, which focuses on nanobubble technology for water treatment and related industries, says it has already supplied oxygenation and water treatment technology to aquaculture operators in Chile.
The companies said they aim to expand the use of their combined approach across the country’s salmon farming areas.
