During the third year of my MEng Mechanical Engineering Degree at Lancaster University I was expected to compete a large individual project. The aim of my project was to develop a new way of aerating water in wastewater treatment with a reduced energy cost that could be retrofitted to existing facilities.The new system, called "Persephone", uses the principles of a siphon to achieve this. The water passing around the downward bend causes a negative pressure difference; which if an inlet is present, will naturally draw air into the system. The goal was to prove whether the concept could be commercially viable.
