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…

Lakes remain open during algae season

Control Cyanobacteria concentration Four solar-powered algae control systems were installed in the Aquadrome in Rickmansworth (UK) to control the cyanobacteria concentration in two lakes. Two systems were installed in a lake used for water skiing and fishing, and two additional unites were installed in June 2017 in a lake used for sailing. To ensure that the concentration of cyanobacteria remained at an acceptable level at a popular public open space…

Eliminated chemical usage in the raw water reservoir

Addressing episodic taste and odor events Four solar-powered algae control buoys were installed in the Canoe Brook Reservoir #1 in Short Hills, NJ to assess the impact of the system for controlling algae and cyanobacteria in the raw water reservoir. The four buoys operated for five months in the spring/summer 2014. As an alternative to copper-based algaecides, the use of ultrasonic treatment can be used to control algae. Ultrasonic treatment uses high frequency sound waves to attack the algal cells….
