SwanCav® — Smart Buoy for
Controlling Harmful Algal Blooms
for a Balanced Ecosystem
Technology
Prasinos Tech’s SwanCav® works on the principle of low power ultrasonic wave that travels through the water as a pressure wave to restrict the algae growth in the water body. The ultrasound creates a pressure zone on the upper layer of the water which interferes with the algae’s buoyancy regulation, preventing them from accessing sunlight and nutrients.
Ultrasonic Operation
Designed with low-power ultrasonic emitters, the system delivers continuous algae control with minimal energy consumption, ensuring cost-effective and sustainable operation.
Chemical-Free
Utilizes targeted ultrasonic frequencies to inhibit algae growth without the use of chemicals, preserving water quality and protecting aquatic ecosystems.
Wide Coverage
Engineered for optimal ultrasonic wave propagation, enabling effective treatment across large water bodies such as lakes, reservoirs, and ponds.
Improved Water Quality
Effectively reduces algae blooms, leading to clearer water, reduced odor, and improved overall aesthetic and environmental quality.
Low Maintenance
Robust design with minimal moving parts ensures long-term, uninterrupted operation with negligible maintenance requirements.
PERFORMANCE COMPARISON
| Performance Parameter | Ultrasonic Algae Control | Aerators | Algaecides / Bio-Enzymes |
|---|---|---|---|
| Algae Reduction Efficiency | 70–99% reduction depending on species & exposure time | Typically 10–35% indirect reduction | 60–95% immediate kill rate |
| Time to Visible Results | 3–14 days continuous operation | Weeks to months | 24–72 hours |
| Long-Term Algae Prevention | Continuous bloom prevention | Limited prevention capability | Requires repeated dosing |
| Power Consumption | 50–500 W typical system load | 0.75–10+ kW depending on pond size | Low electrical load but high chemical dependency |

| Impact on Aquatic Ecosystem | Safe for fish & aquatic life | Generally safe | Risk of toxicity & oxygen depletion |
| Maintenance Requirement | Minimal — no moving mechanical parts | Frequent mechanical maintenance | Continuous dosing & monitoring |
| Lifecycle Cost | Lowest over long-term operation | Moderate | Highest due to recurring chemical purchase |
| Environmental Sustainability | Eco-friendly & non-invasive | Moderate | Potential ecological imbalance |
| Coverage Capability | Up to several hectares per system depending on design | Localized mixing only | Entire pond requires repeated treatment |
| Initial Investment (CAPEX) | Moderate | Moderate to High | Low |
| Annual Operating Cost (OPEX) | Low (power only) | Medium to High (continuous energy) | High (recurring chemicals) |
| Recurring Cost | Nil | Energy + maintenance | Continuous chemical purchase |
| Payback Period | 12–24 months | 2–4 years | No real payback (recurring expense) |
| 5-Year Total Cost | Lowest (30–60% savings) | Moderate | Highest (2–3x ultrasonic) |
| Return on Investment (ROI) | 150–300% over 5 years | 50–120% | Negative / Low ROI |
| Cost Predictability | High (fixed energy cost) | Medium | Low (chemical price fluctuations) |
