My Profile

About

Sean Mulligan is the founder and CEO at VorTech Water Solutions Ltd. Having focused his PhD research on the deep research field of vortex flows, Sean subsequently went on to develop an innovative wastewater treatment technology at University of Galway, which is the basis of the VorTech University spin-out company founded in 2019. This new class of technology, “Vortex Powered Aeration”, which reduces operational costs of treatment, is protected by three international patents. Sean is currently responsible for vision and management of the company's commercial and strategic initiatives. He is also currently the Chair of the IAHR Technical Committee on Hydraulic Structures. Sean’s ambition is to continue developing and translating practical hydraulics research ideas into tangible products and solutions to solve the most pressing challenges of the global water industry.
