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.

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)
Ultrasonic Coverage and System Capability
800 meter Coverage
Large lakes require fewer units compared to typical ultrasonic systems
10,000 CSR Frequencies
Precision targeting across varying cyanobacteria species and lake conditions.
Solar Ready
Off-grid deployment suitable for remote lakes and protected environmental sites.

Technical Benefits of Ultrasonic Algae Control in Lakes

CSR Ultrasonic Range
Broad-spectrum ultrasonic algae control using CSR frequencies designed for lake water treatment applications.

Non-Chemical Treatment
A chemical-free lake algae control system that operates without dosing, substrates, or physical disturbance.

Solar-Ready Deployment
Supports off-grid ultrasonic lake treatment using solar-ready configurations for remote or sensitive sites.

Silent Continuous Operation
Provides continuous ultrasonic lake management with silent operation suitable for public and cultural environments.

Ultrasonic control scope for lakes

Cyanobacteria Control
Suppresses buoyant cyanobacteria, reducing surface scums and bloom persistence.

Water Clarity Improvement
Supports clearer water appearance and improved visual amenity over time.

Biofilm Reduction
Limits biofilm formation on intake structures, weirs, and lake infrastructure.

Sediment & Nutrient Support
Disrupts internal nutrient cycling linked to settled algal biomass.
Commercial & Deployment Pathway

Step 1: Lake Assessment
Initial lake algae assessment to evaluate cyanobacteria risk, site conditions, and suitability for ultrasonic treatment.

Step 2: Site Profiling
Detailed lake water quality profiling, including bloom history, bathymetry, and deployment mapping.

Step 3: Ultrasonic Trial
Controlled ultrasonic lake algae control trial to validate performance under real site conditions.
If you require ESG or sustainability reporting alignment, we can define the trial metrics and documentation format during assessment.
