Membrane distillation (MD) has a great deal of potential and this is currently being explored by the scientific community. However, this technology has not yet been implemented by industry, and an estimation of final product costs is key to its commercial success. In this study a techno-economic assessment of air gap MD (AGMD) and water gap MD (WGM...
Desalination and water reuse are important means to resolve local water scarcity and security issues worldwide where membrane distillation (MD) may be part of a solution. Natural organic matter and in particular, humic acids (HA), are widely present in water supplies to be treated but exhibit little understood behavior to diffuse through MD membran...
Water pollution by metals and, in particular, acid mine drainage (AMD) is one of the most severe environmental problems to be faced by society. In this sense, treatment by membrane processes is a promising alternative, highlighting membrane distillation (MD) features to overcome the limitations of conventional processes. In this work, water gap MD...
Cruise ship wastewater discharges are pollution sources towards the marine environment that are poorly characterized. In this study, wastewater samples from cruise ships have been obtained during repair works in a shipyard. Different organic pollutants have been analyzed and their concentrations were similar to those in urban wastewaters for pharma...
Cruise tourism has experienced in recent years an important growth both in the size of its ships and in the number of transported passengers. These vessels produce a large amount of wastewater that has not been studied in depth. International convention MARPOL (IMO 73/78), allow the discharges to the ocean of these wastewater if they are treated (3...
Reverse Osmosis (RO) shows high potential for the treatment of pulp mill effluents in order to significant reduce stream volumes as well as to produce an excellent effluent quality. However, as a consequence, it is generated RO concentrate with recalcitrant organic compounds that should be treated in parallel. In that way, Advanced Oxidation Proces...
Membrane technology has become a fundamental unit operation in the industry and society of nowadays and fouling is, probably, the most important concern related with this technology. Fouling is a complex process that can limit the performances of facilities using membranes. Many research efforts have been done in order to reduce fouling tendency. C...
