Ultrasonic lake algae control uses targeted acoustic frequencies to disrupt cyanobacteria buoyancy, preventing harmful algal blooms without chemicals.
Lake Ultrasonic Algae Control (CSR)
Hydro Synergy applies low-power Critical Structural Resonance (CSR) ultrasound to suppress cyanobacteria and nuisance algae, reduce bloom persistence, and support clearer water without chemical dosing, dredging, or disruptive mechanical works. Outcomes are site-dependent and guided through assessment, configuration, and monitoring.
Serving distributors in lake management, reservoir water quality, and environmental technology markets.

Proven Cyanobacteria Control in New Zealand Lakes
Lake Tewa, New Zealand | Field-validated deployment
Independent lab analysis confirmed cyanobacteria reduction after ultrasonic deployment.
↓ Cyanobacteria — Lab-verified reduction
↑ Water Clarity — Visible improvement
↓ Bloom Pressure — Harmful algae suppressed
How CSR ultrasound works in lakes?
CSR targets buoyant cyanobacteria by disrupting gas vesicles. Cells lose buoyancy, sink out of the photic zone, and bloom persistence reduces. CSR also disrupts biofilm adhesion and supports natural settling of suspended solids, improving aesthetics and reducing infrastructure biofouling.
Deployment Strategy (site-specific)
-
Cyanobacterial speciation (microscopy or qPCR)
-
Bathymetric and flow mapping
-
Nutrient profiling + historical bloom records
Typical placements:
-
Land-based solar or SolaRAFTs (line of sight for sonic efficacy)
-
Along inflow points (pre-treat nutrient entry)
-
Near intake heads (protect downstream assets)
