Reduce pH levels of the discharge

Excessive algae growth in cooling ponds of power generation facilities can be a significant cause for pH levels to exceed NPDES permissible limits.

In electric power generation facilities, cooling ponds are used for storing heated water and supplying cooling water to the power plant. When discharging the cooling water, power plants need to comply with NPDES effluent requirements. Control algal blooms with LG Sonic ultrasound technology to lower pH, TSS and BOD levels.

NIPSCO case study
NIPSCO chooses a greener path to comply with NPDES

Complying with NPDES regulations In the search of an eco-friendly and effective solution to comply with NPDES discharge regulations, NIPSCO installed 5 MPC-Buoy systems at R. M. Schahfer Generating Station in Indiana, USA. High TSS and pH are mainly caused by algal blooms which are now treated with the ultrasound technology of LG Sonic. NIPSCO uses a large reservoir for settling out suspended solids prior to discharging the water back…

Improved water quality with 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 recycled water for irrigation every day. TSS levels need to be low to fulfil the demands of modern irrigation systems. Algae increases TSS and clogs the filters that are in place to remove TSS prior to the distribution to the irrigation systems. This allows for less…

73% blue-green algae reduction in Dubai

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…

Causes of elevated pH

Elevated pH levels can be caused by a various range of mechanisms such as algal growth, high nutrient levels of the source water, and chemicals used in cooling operations in the power plant.

Excessive algal growth causes pH levels to increase through photosynthesis, in which carbon dioxide is rapidly extracted from the water source water with high salt content entering the cooling pond can provoke e an increase of pH levels. Nutrient-rich water can indirectly influence pH levels too, by accelerating algal growth.
