The purpose of this paper is to analyze the effectiveness of ultrasonic technology to manage algal blooms in Lake Rockwell. Lake Rockwell is the drinking water source for the city of Akron, OH and the surrounding areas. One of the main issues facing the City of Akron Water Treatment Plant is cyanobacteria, or blue-green algae. Cyanobacteria releases toxins, which makes conventional water treatment processes more difficult. Our proposed solution to manage algal blooms in Lake Rockwell is ultrasonic technology. This system emits vibrations that destroy the algal cells and prevent new blooms from forming. Our plan involves three master buoys and ten slave buoys which are placed strategically throughout the lake to destroy the algae and also relay water quality information. This report also includes a cost analysis for the implementation of an ultrasonic system.
