Microalgae grow rapidly when favourable conditions, such as warm and calm water, sufficient sunlight and nutrients, are present, and can lead to low levels of oxygen in water. When microalgae die, the decomposition process also consumes dissolved oxygen and releases nutrients back to the water. This decreases the dissolved oxygen levels in the water, and results in constant regeneration of microalgae under favourable conditions.
The ACU comprises of emitters and receivers which are energised by a power unit during operations. The ACU amplifies the ULF wave, creating a disinfection effect on bio-organisms.
ULF technology-based algae control treatment system has proven to be suitable for application in waterways and reservoirs that are accessible and face issues with excessive algae growth. The system can help with algae control in localised areas.
