Algal bloom and eutrophication pose serious problems to water production from water treatment plants. The toxic that certainly produced from the enzyme secretion by algae also contribute the risk to human health. To control and identify the algal bloom and eutrophication in Sembrong Barat Dam, LG Sonic MPC-Buoy was used. This device uses ultrasonic waves to break down the gas vesicle and cell wall of algae. However, an accurate and reliable mathematical representation for algae disintegration is important to better manage the algal bloom. In this study, the used of Fourier Trigonometry form was fitted. The data were recorded for 14 months, from November 2014 to December 2015. Oscillatoria, actual algae, and chlorophyll-a, has measured using the FlowCAM imaging. Using the equation developed to calculate the sonic wave impact on algae is significant to advance a better understand on the breakdown of the algae cell. The osmosis process occurred once the sonic wave ruptured the cell wall.The derivation of the equation is benefited to determine the energy used to breaking the cell wall or membrane and cytoplasm.
