Water enriched with its natural isotopes plays an important role in research and technology. Heavy water (HDO, D2O) is used in nuclear technology and research and the increasing market demand is expected in future if nuclear fusion will be used for energy production. Water enriched in O is used in research and medicine in trace experiments, as is water enriched in O. Recently there appears to b...

A two-dimensional numerical model for a direct contact membrane distillation (DCMD) module, mostly used desalination and wastewater treatment, has been created. This to explore the sensitivity of simulated transmembrane flux water vapour modelled module some commonly-used assumptions simplifications related mass transport in membrane, namely: equimolar diffusion; Knudsen diffusion-free transpor...

As a consequence of the increase in reverse osmosis (RO) desalination plants, number discarded RO modules for 2020 was estimated to be 14.8 million annually. Currently, these are disposed nearby landfills generating high volumes waste. In order extend their useful life, this research study, we propose recycling and reusing internal components modules, membranes spacers, membrane engineering dis...
