The results of osmotic membrane distillation carried out for 2.5 years were presented in this work. The influence of the process conditions, such as temperature and brine concentration on the permeate flux, was investigated. The saturated NaCl solutions and distilled water were used as a stripping solution and feed, respectively. A continuous regeneration of stripping solution was conducted usi...

Fresh juices of colourful wild berries: cornelian cherry, blackthorn, white beam and elderberry are considered as valuable, highly nutritive beverages and characterized by the high level of vitamins and antioxidant capacity. The concentration process of these juices by membrane osmotic distillation was studied, where only water vapour is eliminated, while the heat sensitive, valuable compounds ...

the energy requirement of vacuum membrane distillation (vmd) with or without recirculation was modelled using both experimental results and theoretical data. the trends are generally consistent between the theoretical and experimental data. thermal energy contributes the most to the total energy required for the vmd process. to lower the thermal energy cost, waste heat resource and heat recover...

Osmotically-driven membrane processes, including forward osmosis (FO) and pressure retarded osmosis (PRO), are emerging technologies that have come under renewed interest and subjected to numerous investigations in recent years. In FO, water is extracted from a feed solution utilizing the high osmotic pressure of a concentrated draw solution (DS) that flows on the opposite side of an FO membran...

Osmotic distillation (OD) has been a subject of interest during the last few years due to its promising application in production low alcohol strength wines. This work focuses on partial dealcoholization (-3 v/v%) red wine (tempranillo) by OD, carrying out an experimental and theoretical process analysis. The was performed using polypropylene hollow fiber module at different conditions whose in...

This paper presents as main contribution the combination of membrane osmotic distillation (OD) to dealcoholize red wine with hydrophobic-hydrophilic pervaporation (PV) carried out add value wastewater (extracting water) produced in OD, recycling water and generating bioethanol. Membrane OD a commercial polypropylene hollow fiber module was applied partially from 14.0 11.0 v/v% ethanol. The extr...

the possibility of applying membrane distillation to support the fermentation process was investigated. the capillary polypropylene membranes were assembled in the membrane modules. the studies were carried out using the standard solutions containing the compounds frequently occurring in the broths such as ethanol, citric, acetic and lactic acids, glycerol and 1,3-propanediol. the performance o...
