Lakes can breathe again: Introducing the MPC-NanoBubble

It’s a monumental day for LG Sonic, as it expands from ultrasonic algae control to an algae management company. The latest technology, the MPC-NanoBubble, is an autonomous mobile platform that uses pure oxygen nanobubbles to increase dissolved oxygen levels in large water surfaces.

Anoxia occurs when water bodies are depleted of dissolved oxygen. In these conditions, fish can suffocate and die. Furthermore, there is a risk of potentially harmful components being released from the sediment, such as phosphorous, heavy metals or manganese. To increase oxygen levels in water bodies, LG Sonic introduced the MPC-NanoBubble.

The MPC-NanoBubble
The system is a mobile platform that automatically adjusts its location to ensure the coverage of the entire surface of large water bodies. The MPC-NanoBubble moves around the water surface in a spiral motion, detecting the areas where oxygen levels are too low. When the anoxic area is detected, the MPC-NanoBubble applies pure oxygen until the DO has reached the desirable level. The use of pure oxygen as a source increases the efficiency of the device by up to five times.

The smaller a bubble in the water is, the slower it moves through the water – nanobubbles do not move through water columns, but remains in the water delivering its content to the water surrounding it

The system makes use of a flexible power source such as a generator or batteries. This and the mobility of the device ensures tremendous savings on energy compared to conventional (nano) aeration. The nano-size of the bubbles ensures they will no longer move vertically through the water column. Instead, all nanobubbles remain in the water until they have been used entirely, from three weeks up to two months.

The MPC-Nanobubble has already been nominated for the Aquatech Innovation Award 2019. The jury recognises the best innovations and technologies worldwide that have the ability to drastically change the international water market.
