Reduce algae to improve the water quality

Treated wastewater usually contains high levels of nutrients that can cause algal blooms on the water surface of storage ponds. An excess of algae can increase levels of pH, BOD and TSS, making reuse or discharge of the water difficult.

Control algae with LG Sonic ultrasound to have higher quality water that is safe to release back in the environment.

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…

Algae growth in stabilization ponds

An important issue to consider in wastewater reuse and treatment is algae growth, which is relatively common in warm and nutrient-rich waters. Treated wastewater usually contains high levels of nutrients that can cause algae blooms on the water surface of storage ponds and clog irrigation systems (filters, emitters, distribution pipes). Furthermore, some freshwater algae can form harmful algal blooms (HABs), and these specific species create health hazards for humans and animals by producing toxins and bioactive compounds that deteriorate the water quality.

Although there are several methods to treat wastewater, this article focuses on stabilization ponds (also called lagoons or waste stabilization ponds). These types of ponds and lagoons consist of in-ground earthen basins in which the waste is detained for a specified time (retention time) and then discharged. The size and depths can vary, as well as the degree of treatment. Lagoons are typically classified by their degree of mixing and amount of oxygen dissolved in the water. Examples of lagoons are anaerobic lagoon, facultative lagoon, aerobic lagoon, partial-mix aerated lagoon, and completely mixed- aerated lagoon.
