02 · BENEFITS
Measurable results, regulatory compliance, and sustainability in every project.
01
Constant oxygen injection through nanobubbles raises dissolved oxygen concentration, supporting ecosystem repair and removing nutrients like nitrogen and phosphorus.
02
We support seabed recovery under anaerobic conditions by injecting neutrally buoyant nanobubbles that remain suspended in the water column for months.
03
Oxygen transfer above 90%, with efficient costs compared to other aeration methods. Your site returns to operation faster.
04
Raising dissolved oxygen levels improves water quality and recovers damaged ecosystems, restoring marine flora and fauna.
03 · TECHNOLOGY
Gas particles 2,500 times smaller than a grain of salt that maximize oxygen dissolution in water. They stay suspended for months, increasing dissolved oxygen and promoting oxidation of organic matter accumulated on the seabed.
04 · FULL EQUIPMENT TEAM
We operate a fleet of vessels and equipment ready for seabed remediation in Regions X and XI. Capacity to remediate Category 3, 4, and 5 sites, adapting to your operational windows. Continuous ROV monitoring throughout the process.
Capacity for all categories
Operations from Puerto Varas
Continuous supervision throughout the process
05 · PREVENTIVE
Biological waste buildup can lead to critical organic contamination if not managed in time. Acting before deterioration avoids costlier corrective interventions.
Operation antes before an INFA is declared. Avoid escalating to Category 3+ and keep your concession running without interruption.
Operation after after an INFA is declared. We resolve Category 3, 4, and 5 with generators of up to 10 kg/h.
06 · SERVICE
01
Technology that keeps the seabed in optimal condition, supporting a healthy ecosystem and meeting environmental regulations.
02
An ongoing remediation service that prevents bacterial growth and the buildup of accumulated organic matter.
03
Our team supervises the process in real time, ensuring maximum oxygenation efficiency and ecosystem stability.

09 · FREQUENTLY ASKED QUESTIONS
Seabed remediation is a process aimed at restoring the health of marine ecosystems affected by human activities such as aquaculture. It includes techniques like nanobubble oxygenation and sediment management. It matters because it improves water quality, recovers marine habitats, and safeguards biodiversity sustainability.
The service begins with requesting environmental permits under Resolution 1141 and continues with oxygenation adapted to the site. It includes: proven results at Cat 3, 4, and 5 sites; a certified-lab INFA comparing initial and final levels; and procedures compliant with Resolution 1141.
Remediation can be carried out both during fallow periods and at operating sites. We ensure the process does not interfere with operations or affect the fish.
Our industrial nanobubble generation systems inject oxygen continuously or intermittently, adapting to the site’s size. This ensures optimal production conditions, reducing mortality and improving fish health and growth.
Remediation can take between 3 and 4 months, depending on weather conditions and the operation. In hatcheries, results are immediate, visible in under a week.
We use oxygen generators with capacity up to 10 kg/h built to run 24/7. We offer personalized service, full support, and a certified final report. We limit simultaneous projects to guarantee quality.
Yes. We only inject oxygen through nanobubbles, which has no negative effect on fish or nearby organisms. To ensure sediments aren’t resuspended, we monitor water turbidity per Resolution 1141.
