Real-Life Testimonials

"We have 5 primary reservoirs… We obviously couldn’t cover all our surfaces, so we decided to deploy 2 of the units. Within the first month, we were seeing results. As a result of findings, we placed an order for 3 additional units for the remaining reservoirs. We are pleased with the results"

Our Applications

Targeted Algae Control for Every Water Body from Lakes and Ponds to Wastewater and Drinking Supply

fish with water waves icon

Dairy
Ponds

Ultrasound breaks down algae, stabilises dissolved oxygen, and reduces sludge buildup in dairy effluent ponds. This improves water clarity, controls odour, and helps you meet environmental compliance with less chemical use.

Learn More
fish with water waves icon

Ponds
​

Ultrasound effectively treats nuisance algae and sediment in storage, runoff, and landscape ponds. It improves water clarity, protects pond aesthetics, and reduces cleaning and maintenance costs.

​

Learn More
fish with water waves icon

Lakes
 

Ultrasound reduces toxic algal blooms, clears suspended solids, and supports oxygen balance. This helps improve water clarity, restore biodiversity, and reduce the need for chemical dosing.

​

Learn More
fish with water waves icon

Drinking
Water

Ultrasound targets cyanobacteria, biofilm, and suspended solids before they reach the drinking water treatment plant. It improves taste, clarity, and system efficiency while lowering chemical and filter load.

Learn More
fish with water waves icon

Wastewater
 

Ultrasound reduces total suspended solids, accelerates sludge dewatering, controls cyanobacteria, and improves plant performance. This supports discharge compliance, reduces chemical use, and enhances water clarity across all treatment stages.
