Reducing algae growth

In August 2018, LG Sonic began a new project in Dubai in collaboration with the Dubai Municipality to control algal blooms in the Al Qudra lakes. The lakes were created by the municipality as part of a project to enrich this part of the Dubai desert. To control the algal blooms, three MPC-Buoys were installed. After 60 days, it was clear that the systems improved the water quality dramatically.

Since the installation of MPC-Buoy the water quality has improved dramatically.

The Dubai Municipality selected MPC-Buoy systems to control algal blooms due to its chemical-free technology and real-time water quality monitoring capabilities which allow insights into important water quality and algae parameters. Each MPC-Buoy unit can treat algal blooms up to 500 meters/1600 feet in diameter. In larger reservoirs, multiple systems are used to cover the entire water surface.

Massive improvements

60 days after the installation of the MPC-Buoy systems, the chlorophyll-a and Phycocyanin concentrations of two lakes at the same site were compared. One lake was treated by LG Sonic, and the other lake was left untreated. The algae concentration in the treated lake was reduced by 50% on the average. From 100 ug/L to 50 ug/L. The Blue-green algae concentration was reduced by 73% on the average. From 675 ug/L to 180 ug/L. Based on these results, the Dubai Municipality is looking to treat more of their reservoirs and lakes with LG Sonic MPC-Buoy.

 Improving water quality In sunny California, MPC-Buoy technology is controlling algae in reclaimed water since 2018. Vallecitos Water District provides 5.25 million gallons of recycled water for irrigation every day. TSS levels need to be low to fulfil the demands of modern irrigation systems. Algae increases TSS and clog the filters that are in place to remove TSS prior to the distribution to the irrigation systems. This allows for…
