Ultrasonic Biofouling Prevention

The LG Sonic Industrial Line provides a cost-effective solution to control algae and prevent biofouling with the use of ultrasound technology.

    • Multiple ultrasonic programs for effective biofouling prevention
    • Ultrasonic treatment allows for the reduction of chemical consumption
    • No use of cavitation for a longer product lifetime

Biofouling process in five stages

Biofouling process

The process of biofouling starts with the attachment of bacteria to a surface. These bacteria subsequently start producing EPS, also called extra polymeric substances, that forms the structure of the biofilm. To this layer, other organisms such as algae, weeds, parasites, muscles or even barnacles may attach. At this point, the biofilm has become biofouling.

How it Works - Ultrasonic Biofouling Prevention

With the use of specific ultrasonic frequencies, waveforms and amplitudes it is possible to directly target the biofilms.

1. Prevent biofilm

LG Sonic products emit ultrasound at multiple frequencies, waveforms and amplitudes. These frequencies prevent the bacteria from settling to a surface in the primary stage of the formation of a biofilm.

2. Alter structure biofilm

The specific ultrasonic program alters the structure of an existing biofilm and eventually breaking it down.

3. Control biofilm

The ultrasound removes the algae attaching to a biofilm. These effects result in longer cleaning intervals and improved efficiency of the heat exchanger and cooling system.

Microbiological Control in cooling water system

At the Al Futtaim Cooling district, chemicals were used in the cooling tower water treatment. The plant incorporated the LG Sonic cooling tower algae control technology into their chemical treatment program to reduce the biocide consumption in the cooling towers and improve the water quality.

    • Up to 69% reduction in biocide dosage
    • Up to 53% reduction in anti-scalant dosage
    • Microbial analysis of the water after tests of satisfactory quality and within specific limits
