Lab Tested. Lake Approved.

We didn’t just build a machine; we proved it works. Working alongside Eget Liber, who patented the core technology, and SUNY ESF’s cyanobacteria experts, who validated its effectiveness in lab testing, CyanoShark has demonstrated the ability to rapidly destroy blue-green algae whilst preventing the release of harmful toxins.

The Efficiency Test: 96.5% Reduction in 24 Hours

We measured active chlorophyll levels to see how fast CyanoShark works compared to doing nothing.

This diagram shows CyanoShark’s triple-phase technology gently disrupted the algae without triggering a spike. Toxin levels remained stable and significantly lower than the control throughout the entire 17-day trial.
  • The Baseline: We started with equal concentrations of algae-rich water.

  • The Control (Orange): Left untreated, the algae bloom continued to expand, growing by 27% in density.

  • The Solution (White): The water treated by CyanoShark saw a massive 96.55% reduction in active chlorophyll within just one day.

 

The Takeaway: While nature lets blooms grow, CyanoShark neutralizes the threat almost immediately.

The Safety Test: Preventing the "Toxin Bomb"

The biggest fear in algae treatment is “cellular lysis”, popping the algae cells and releasing a massive spike of stored toxins into the water.

How RanMarine's CyanoShark prevents blue green algae by treating it using its patented SFTS system, The diagram shows the Efficiency Test: 96.5% Reduction in 24 Hours. 
  • The Risk (Orange Line): In the untreated control group, as algae naturally died off, it released a dangerous spike of microcystins (toxins) around Day 10.

  • The Solution (White Line): CyanoShark’s triple-phase technology gently disrupted the algae without triggering a spike. Toxin levels remained stable and significantly lower than the control throughout the entire 17-day trial.

The Takeaway: We don’t just kill the algae; we protect the ecosystem from the toxins left behind.

CyanoShark

TARGETED ALGAE DEFENSE

Autonomous precision. Chemical-free control for healthy waterways.

Meet the CyanoShark: The CyanoShark operates through a sophisticated combination of autonomous navigation and specialized treatment technology. Its advanced sensor array, including LiDAR, GPS, and an Inertial Measurement Unit (IMU), enables independent navigation along pre-programmed mission routes or real-time operator control, ensuring precise coverage of bloom areas.

Made in the European Union: Assembled in Rotterdam, this professional environmental solution utilizes Dutch-manufactured propulsion and the patented Staged Flow Treatment System (SFTS) developed by Eget Liber.

SFTS Technology: The Staged Flow Treatment System features strategically designed multi-angled baffles that guide buoyant cyanobacteria into an onboard reactor. Once captured, a multi-modal approach (using Ozone, Ultrasound, and UVC) neutralizes the algae.

Real-Time Monitoring: 4G connectivity provides continuous data transmission and operational oversight. Real-time water quality monitoring ensures optimal treatment effectiveness, reducing the need for manual intervention.

Chemical-Free: The system safely disrupts harmful algae without releasing chemicals into the water. This targeted approach focuses on the top layer of the water column, minimizing impact on benthic organisms and other aquatic life.

Frequently Asked Questions

The CyanoShark is an autonomous surface vessel (ASV) specifically designed to detect, monitor, and neutralize harmful blue-green algae (cyanobacteria) blooms. Unlike standard skimmers, it uses an onboard treatment system to safely eliminate algae without using harmful chemicals.

While the WasteShark is designed to collect solid waste (trash, plastic, biomass) into a basket, the CyanoShark is a treatment vessel. It does not collect debris; instead, it intakes water, passes it through a specialized Staged Flow Treatment System (SFTS) to kill the algae, and releases the clean water back into the ecosystem.

Yes. It features advanced Waypoint Navigation (LiDAR and GPS) allowing it to follow pre-programmed routes to treat specific zones automatically. It can also be operated manually via remote control for spot treatments.

No. The CyanoShark is a chemical-free solution. It targets only the top layer of the water column (where algae accumulates). The ozone used in the treatment process naturally reverts to oxygen before the water is released, ensuring no harmful residues are left behind for fish or plants.

It is specifically engineered to target Cyanobacteria (Blue-Green Algae) and harmful algal blooms (HABs). It is effective against surface scums and blooms that produce toxins like Microcystins.

The CyanoShark runs on electric propulsion with a battery life of up to 2.5 hours of continuous operation per charge. It takes approximately 5 hours to fully recharge using standard shore power.

It is designed for “Simple Operation.” The interface is intuitive, and your existing facilities team can deploy and operate the drone effectively with minimal training. No specialized captain’s license is typically required for operation in private or controlled waters.

No. Since the CyanoShark uses a flow-through treatment system (intake > treat > release), there is no basket to empty. It can operate continuously for its full battery life without stopping to unload.

While most harmful blooms occur in freshwater, the CyanoShark is built to operate in saltwater, freshwater, and brackish water. This allows it to treat marine cyanobacteria (like Lyngbya) and operate in estuaries or coastal marinas without risk of corrosion to the vessel.

Yes. Chemical treatments often kill non-target organisms and can leave toxic residues that settle in the sediment. The CyanoShark offers a localized, eco-friendly alternative that neutralizes algae physically and biologically without poisoning the water column.

The drone has a remote control range of 1000 meters (1094 yards), allowing the operator to stay safely on shore while the drone treats distant blooms.

The CyanoShark can treat approximately 2100 m² (22,604 ft²) of water surface per hour, processing roughly 168,000 liters of water in that time.
