Prevent biofouling growth

Algae can grow in the cooling tower itself and on the grids from the tower. This could lead to enormous disadvantages of biofilm in cooling towers. Therefore, water used in cooling towers needs frequent treatment and chemical shocks to keep levels of micro-organisms to a minimum.

The LG Sonic Industrial Line allows to reduce chemical dosage and offers local treatment were biofouling growth can’t be prevented with chemicals.

Case studies

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…

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 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…

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…

Biofilm formation

In a cooling system there are billions of bacteria which are held together by a slimy substance (EPS). The formation of a biofilm, or biofouling come into existence when the bacteria stops moving, settles down and becomes part of a biofilm. To this layer, other organisms such as algae, weeds, parasites, muscles or even barnacles may attach.

Due to biofouling- negative effects may occur such as increased chemical consumption, corrosion and increases in power requirements of the system.
