Precision ultrasound for algae & biofilm remediation
The Pulsar Family (Pulsar 3400 & 4400) is an advanced ultrasonic platform that uses 4,400 precisely tuned frequencies to disrupt algae and associated biofilm in high-value water bodies — without relying on chemicals.
Pulsar 3400 is configured for smaller or enclosed applications such as ponds, tanks and clarifiers, while Pulsar 4400 extends range and power for large lakes, reservoirs and critical industrial or municipal assets. Both systems can be deployed on floats, land-based frames or solar-powered Sentinel platforms.
Fast Facts
- 4,400 ultrasonic frequencies to target a broad range of algae and biofilm.
- Targets most green and blue-green (cyanobacteria) algae plus selected golden and red tide–type species.
- Pulsar 3400: designed for smaller bodies of water and enclosed assets; Pulsar 4400: for larger, high-value sites.
- Four piezo transducers per head (4 × 90°) provide 360° coverage.
- Continuous 24/7 operation with telemetry and IQCloud connectivity for monitoring and optimisation.
- Configurable power options — AC, DC and solar (including Sentinel AIQ/+ packages).
- Chemical-free and designed to be safe for fish, plants and other aquatic life at the operating frequencies used.
Non-biocidal, equipment-based algae and biofilm control
Pulsar systems treat algae and biofilm using physical ultrasound rather than biocidal chemicals. This helps reduce the handling, storage and discharge considerations associated with traditional algaecides and herbicides, while supporting your broader water-quality and ESG objectives.
Regulatory requirements for non-chemical treatment devices differ by jurisdiction. Our team can help map Pulsar into your compliance framework and integrate telemetry and water-quality data into your existing reporting and risk-management processes.
High-precision ultrasound targeting critical algal structures
Pulsar units emit a rapid sequence of ultrasonic frequencies that interact with gas vesicles, flagella and other cellular structures in susceptible algae. When these structures are driven near their resonant points, they are damaged and the cells lose buoyancy and mobility, sink out of the light zone and break down — without releasing additional toxins into the water.
Continuous 24/7 treatment also disrupts early-stage biofilm formation on structures, helping to keep clarifiers, tanks, screens and other assets cleaner with less manual intervention.
Where it fits
- Wastewater — clarifiers, settling ponds & lagoons
Reduce biofilm on structures, improve process stability and cut the effort needed to keep clarifiers and ponds clear. - Drinking water — reservoirs & plants
Mitigate cyanobacteria and nuisance algae in source waters and treatment assets, supporting taste, odour and overall aesthetic water quality. - Golf, HOA & municipal — water features & irrigation resources
Maintain clear, attractive ponds and irrigation storage without repeated chemical treatments, while protecting the value of landscapes and amenities. - Agriculture & irrigation
Support irrigation water-quality requirements, reduce fouling in pumps and distribution networks, and integrate with smart farming and remote monitoring. - Aquaculture
Control harmful algae in fish and shellfish systems with a chemical-free approach that is designed to protect the surrounding aquatic ecosystem.
Application & configuration guidance
Pulsar systems are configured according to water-body shape, depth, inflows and target species. Units can be mounted on floats, land-based A-frames or solar Sentinel platforms, with single or dual heads driven from a shared controller to maximise coverage.
In most applications, Pulsar operates continuously to prevent new blooms and biofilm from establishing. Best results are achieved when ultrasound is combined with good nutrient and solids management — for example, aeration, sludge handling and runoff control.
