Professor Antti Häkkinen holds a professorship in solid/liquid separation at LUT University (Finland) and heads a group of 10 researchers from doctoral students to post-doctoral researchers. Professor Häkkinen has worked on various issues related to solid/liquid separation and characteristics of filter materials and particulate materials for over 20 years. He is an expert in filtration of mineral concentrates, tailings and biomaterials and has extensive experience in combining various chemical engineering phenomena, e.g. crystallization, classification, dissolution and chemical reactions, and empirical modelling with solid/liquid separation. The research group is in its field the only academic research group operating in Finland and is well networked internationally. Professor Häkkinen has authored more than 80 publications in international peer reviewed journals and has presented over 100 papers at international scientific conferences. He has been the chairman of the Nordic Filtration Society (2009 – 2010 & 2014 - 2015) and was a council member of The Filtration Society (UK) from 2010 until 2014. He is a regular reviewer to several international journals and conferences in the field of separation technology, mining and metallurgical engineering.

New Developments in Conservation and Reuse of Water in Industrial Processes

Transition towards more sustainable use of raw materials and resources in the society requires a radical shift from the typical linear take-make-consume-dispose model to the so-called circular economy. One part of this shift is that the resource efficiency of current industrial processes needs to be improved and more importantly, the utilization rate of current waste materials as secondary resources needs to be increased. Solid liquid separation is one of the most common chemical and industrial unit operations and it has a significant role when novel process solutions are being developed. Owing to rising energy prices, increasingly scarce water resources as well as decreasing quality of the primary raw materials, it is essential to strive for stronger energy and water saving solutions in separation processes. In addition, the quality requirements set for the final product of the separation processes are getting tougher at the same time when new innovations raise new performance challenges for separation technologies. Solid liquid separation plays a key role in solving cost efficiently some of these challenges. In this presentation, some developments of novel water treatment technologies in conservation and reuse of water for industrial processes will be presented.
