Six years of partnership with South West Water

6 years

This project is running since 2014


Natural balance of algae growth

Key component

In South West Water's treatment process

Sustainable partnership

Since 2014 South West Water, formerly Bournemouth Water, is using LG Sonic MPC-Buoy systems to monitor and control algal blooms at Longham Lakes. High algae concentrations in reservoirs used for drinking water purposes causes increased chemical dosage and blockages of filters and pipes within the water treatment plant.

South West Water holds health and wellbeing of people and the environment in their core values. Environmental health is critical to water sources such as Longham Lakes. Besides being used as drinking water source for local towns and communities, Longham Lakes is used for agricultural and recreational purposes such as fishing.

Safe water in Longham lakes.

To resolve problems caused by excessive algae growth at Longham Lakes, South West Water selected LG Sonic ultrasound technology due to its environmentally friendly nature. In the beginning of 2014, four MPC-Buoy systems were placed in the lakes. Now six years later, the systems continue to be a key component of South West Water’s treatment process.

Restoring the natural balance

Within the first three months South West Water experienced a dramatic reduction in algae concentrations at Longham Lakes. The MPC-Buoy systems continue to operate till this today with algae levels within satisfying levels for a balanced aquatic ecosystem.

“South West Water was one the first utilities in the United Kingdom to include MPC-Buoy in their water treatment process back in 2014. We are proud of the sustainable partnership between South West Water and LG Sonic”, said Kristin Prantsus, After Sales Manager at LG Sonic.

“We’re working with the supplier who is able to fine-tune the sound frequencies to deal with specific outbreaks of algae“.

Reduced blue-green algae counts in New Zealand

Reducing blue-green algae counts In the Lower Nihotupu Dam in Auckland, New Zealand, five solar-powered algae control systems are controlling blue-green algae blooms. The project started in December 2016 and it proved to be a great success. The algae counts have significantly decreased over the summer, as compared to the previous year. The water utility’s main objective was to reduce blue-green algae counts in a dam used as a water…

Control algae problems A floating solar powered algae control system was installed in Emmitsburg (US) to control algae in a reservoir that provides drinking water to approximately 3,000 people. The MPC-Buoy system, installed in April 2017, succeeds in controlling algae, reducing chemical costs and water usage. The main objective of the project was to reduce algae problems, especially during summer months, with secondary objectives to reduce chemicals costs, decrease backwashes,…

Control and monitor toxic algal blooms The ClearWaterPMPC project was initiated by LG Sound and funded by “Research for SMEs” within the EU 7th Framework Programme. The goal of the ClearWaterPMPC (Predicting, Monitoring,Preventing, and Controlling) project was to develop an environmentally friendly technology to prevent growth of blue-green algae in large water reservoirs. In contrast to currently available ultrasound based algae control systems, the technology developed within the scope of…
