Algae Control in Ponds: reduce chemicals, improve water quality

The algae control devices from LG Sonic emit specific ultrasonic parameters in order to control harmful algal blooms in ponds.

Ponds in golf courses, parks or gardens often have both an ornamental and irrigation purpose. To furnish both, it is important that the water looks clear, is free of any solids and should not contain chemicals that may harm the plant growth. Algae growth within ponds can complicate irrigation, as filamentous algae may clog the pump and suspended algae can clog nozzles later in the system.

Chemical based herbicides and algaecides can be substituted by the LG Sonic technology. Together with a low power consumption, maintenance is reduced to minimum as the equipment can incorporate an automatic Aquawiper™ that will clean the ultrasonic transmitter surface.
