Algae Remediation – with Hydro BioScience’s ARCS™ Technology

26 October 2026

Algae can become a significant water-quality challenge when excess nutrients, warm temperatures, and stagnant conditions promote rapid growth. Harmful algal blooms (HABs), particularly those caused by blue-green algae (cyanobacteria), can reduce dissolved oxygen, create taste and odour issues, impact aquatic ecosystems, and in some cases produce toxins that affect humans, livestock, and wildlife.

To help address these challenges, HydroTerra partners with Hydro BioScience (HBS), a specialist provider of ultrasonic algae, biofilm, and HAB remediation technologies. Unlike chemical treatment programs, HBS systems use high-frequency ultrasonic waves to disrupt the biological processes that enable algae to thrive. By interfering with algae buoyancy regulation, the technology prevents algae from efficiently accessing both sunlight and nutrients, reducing their ability to photosynthesise and proliferate.

At the core of the Hydro BioScience range is patented ARCS™ (Algae Remediation Critical Structural Resonance) Technology, which delivers true 360-degree ultrasonic coverage. This approach helps eliminate the dead zones and weakened signal areas often associated with conventional ultrasonic systems, ensuring more effective treatment across water storages, reservoirs, wastewater lagoons, irrigation systems, aquaculture facilities, clarifiers, ponds, and lakes.

Overview of the solutions available from our key partner Hydro BioScience

 

The Hydro BioScience product portfolio includes the Quattro-DB® range of ultrasonic remediation units alongside the SolaRaft-iQDB™ and SolaRaft-iQM™ floating platforms. Available in both solar-powered and mains-powered configurations, the systems can be deployed in remote locations and monitored remotely.

Key benefits include:

  • True 360° Ultrasonic Coverage
  • Chemical-Free Algae Control
  • Broad Algae Species Effectiveness
  • Low Power Consumption
  • Large Area Coverage
  • Integrated Monitoring and Treatment
  • Rapid Results

 

For organisations seeking greater visibility of water conditions, the SolaRaft-iQM™ platform combines remediation with real-time water-quality monitoring, allowing operators to view conditions remotely and optimise management strategies. Hydro BioScience also reports that positive remediation results may be observed in as little as 14 days, depending on site conditions, nutrient loading, and algae species.
