LG Sonic ultrasound controls buoyancy of planktonic algae

Buoyancy regulation plays a key role in the metabolism of planktonic algae. The ultrasonic pressure produced by LG Sonic influences the buoyancy regulation of the algae. As a result, algae are no longer capable to obtain sufficient sunlight and nutrients.

Sound barrier

1. Create a sound barrier

The ultrasound creates a sound barrier in the upper layer of the water. This affects the vertical movement of algae.

Lack of light

2. Lack of light and nutrients

Due to limited movement, algae do not absorb enough sunlight and nutrients. Therefore, they are not able to perform photosynthesis.

Interactive frequencies

3. Control algae count

Ultrasound does not cause direct cell lysis, so no toxins are released in the water. Algae sink to the bottom and decompose over time.

The short-term solution with a long-term goal of restoring the ecosystem

Algae are the foundation of the food chain in ponds, lakes and reservoirs. LG Sonic technology uses low-power ultrasound to affect the algae mobility. It works continuously to stop their spread and prevent the release of toxins and their consequences in a sustainable way.

Controlling algal growth without negatively affecting other organisms in the water will lead to better light penetration in the water column and lower pH levels. This in turn allows regrowth of benthic plants, with increased levels of dissolved oxygen as a result. Due to these effects, bacteria in the sediment in charge of organic decomposition operate more efficiently, leading to a restoration of the ecosystem in a sustainable manner.

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….
