Abstract

The world of water purification has advanced leaps and bounds in the past several decades, with one of the most groundbreaking discoveries in the field being the use of Ultraviolet Light Emitting Diodes (UVLEDs) to effectively kill bacteria both safely and effectively (Boudenne). This advance has also allowed for a more environmentally friendly approach to water purification, as UVLEDs leave very little byproduct and can be used for extended periods of time without replacement (Bauer). / Though small scale UVLED purification has become more efficient and portable, large scale UVLED water purification systems remain unoptimized to their maximum potential, unable to find a balance between effectiveness and efficiency (Oppenländer). When mass quantities of water need to be purified, the UVLED process is difficult to use, as water must be processed in smaller, individually treated units. This therefore creates the problem of the imbalance of efficiency and effectiveness of water treatment and purification. / In order to solve this large scale problem, I plan to set up and test a UVLED water purification apparatus to find the optimum flow rate at which water can be purified most efficiently, without sacrificing effectiveness of bacteria annihilation. This will be done by altering flow rates at varying intervals and running water at that rate through a UVLED purification system, then measuring the percentage of bacteria killed in each test until the optimum flow rate is found.
