Bath University Team Tests Algae-Management System in Wiltshire Waterbody

Researchers at the University of Bath have launched field trials for an innovative device aimed at limiting toxic algal blooms, installing it in a Wiltshire lake as a proof‑of‑concept demonstration.

The effort arrives as worries mount over the spread of harmful cyanobacteria in UK freshwater sites, a trend tied to warmer temperatures and agricultural nutrient runoff. These blooms can emit toxins hazardous to people, livestock and wildlife, spurring demand for robust mitigation approaches.

The Bath group’s strategy uses a mechanised apparatus that suppresses algae development without chemical additives. Although the precise workings are kept proprietary, the unit functions by modifying local water parameters to render the habitat less suitable for toxin‑producing algae. Initial lab trials indicated a drop in algal density, leading to the transition to field testing.

Throughout the lake experiment, the scientists are tracking vital metrics like chlorophyll levels, dissolved oxygen, and toxin presence. They gather data via a mix of automated sensors and occasional manual samples, enabling comparison between treated sections and untreated control zones. The pilot seeks to determine if the technology can provide reliable and scalable outcomes.

Local stakeholders—such as the lake’s managing authority and surrounding community groups—have embraced the trial, highlighting possible gains for recreation, tourism and public health. Their support has granted site access and helped ensure compliance with environmental regulations.

Should the field outcomes match laboratory predictions, the team intends to fine‑tune the system and consider broader roll‑outs on additional impacted waterways. A successful result could supply a crucial instrument in combating freshwater algal toxicity, supplementing current tactics like nutrient management and public‑awareness initiatives.
