Throughout his career, Roesink has been a trailblazer in the field of membrane technology, particularly in the development of hollow fiber PES membranes for microfiltration, ultrafiltration, and nanofiltration applications worldwide. His journey began in 1985 at X-flow in the Netherlands, where he played a pivotal role in revolutionizing membrane technology.
As a distinguished Professor at the University of Enschede, Roesink continued his groundbreaking work, focusing on hollow fiber membranes with nanofiltration characteristics. His vision was clear – to introduce a new membrane technology capable of addressing global water challenges, particularly micropollutants, while minimizing energy and chemical footprints.
The culmination of Roesink's efforts led to the founding of NX Filtration in 2016. NX Filtration’s HFNF membranes, spearheaded by Roesink’s innovative research, remove micropollutants such as pesticides, hormones, PFAS, pharmaceuticals, and color, along with bacteria and viruses. These achievements have been realized with significantly reduced energy consumption and chemical dosing compared to traditional UF/RO membrane combinations.
