Algae control at Sellafield 

LG Sonic, a leading international manufacturer of algae and biofouling control systems, has installed multiple LG Sonic Industrial Wet Systems at the Sellafield  nuclear power facility in the UK. This led to a significant improvement in the clarity of the water and the visibility into the storage ponds. As a result of these ultrasonic processing systems there has been an exceptional reduction in blue-green algae and chlorophyll levels in the treated storage ponds.

Sellafield, a nuclear fuel reprocessing and nuclear decommissioning site, handles nearly all the radioactive waste generated by the 15 operational nuclear reactors in the United Kingdom. In 2015, the UK government started a major clean-up of the stored nuclear waste facilities in Sellafield because of the bad condition of storage ponds. One of the main causes of these bad conditions  was poor visibility in the water due to algae growth.

The Solution: Ultrasound technology

To improve water visibility in the storage ponds, four LG Sonic Industrial Wet systems were installed. The systems have 12 ultrasonic programmes to effectively control different types of algae, and are able to treat algae in a relatively short time. GPRS control allows the user to monitor and change the ultrasound programme remotely. Furthermore, status updates and alerts are received when power outages occur.

In only three weeks after the installation of the LG Sonic ultrasonic systems, there was a significant reduction in blue-green algae count and chlorophyll levels. As a result of the this reduction, the water started to clear and it was possible to see vessels and containers in the storage ponds that in recent years were only visible when using a tethered underwater mobile camera device.

Over 10,000 LG Sonic systems have been installed worldwide, including many on the current European FP7 projects.
