NIPSCO case study
NIPSCO reduced TSS levels to comply with NPDES regulations

Complying with NPDES regulations NIPSCO began its cooperation with LG Sonic with the main goal of reducing TSS levels to comply with NPDES Regulatory Discharge Limits. Since the installation of 5 MPC-Buoy systems in the spring of 2019, TSS levels reduced to less than 3ppm. R.M. Schahfer Generating Station in Northwest Indiana (United States) consists of four coal-fired units and two natural gas-fired units. To operate, the power station takes…

Dominican Republic case study
87% algae reduction to improve drinking water

The country’s most important water source After years of struggle with algal blooms, The Santo Domingo Water and Sewage Corporation (CAASD) installed multiple MPC-Buoy systems to cover the 7km²/2.7mi² Valdesia reservoir. The first results were visible after two weeks, and the project exceeded the targets for the first year with a 87% reduction in algae levels. The Valdesia reservoir is the main drinking water supply for the population of the…
