In this study, the dynamics of scaled-up membrane distillation (MD) modules are tackled for treatment highly saline desalination brines. Physical phenomena occurring inside feed chamber during process scale-up including temperature evolution, species distribution and scaling likeliness were explored using a multicomponent computational fluid (CFD) model that couples momentum, heat, ions transpo...

Water reclamation is becoming a growing need, in particular developing countries where harvesting the required energy can be challenging problem. In this context, exploiting solar specifically tailored membrane distillation (MD) process viable solution. Traditional MD guarantees complete retention of non-volatile compounds and does not require high feed water temperatures. work, suitable amount...

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 ...

In this work, a procedure to simulate the MD (molecular distillation) process for lactic acid purification was developed. The simulation was carried out with the aid of the Aspen Plus Process Simulator. Flash vessel was used to represent the MD process since the software does not present this unit operation. The simulation results with efficiency factors were in agreement with previously report...

Desalination and wastewater treatment technologies require an effective solution for brine management to ensure environmental sustainability, which is closely linked with efficient process operations, reduction of chemical dosages, valorization brines. Within the scope desalination reclamation, a circular system consisting seawater reverse osmosis (SWRO), membrane distillation (MD), forward (FO...

Background and Objectives: Red beet juice, a potential source of valuable nutrients, is widely used as a colorant in food industries. In recent years, to avoid reduction of nutritional values of the red beet during concentration by thermal processing, an osmotic distillation (OD) technique has been suggested. Therefore, the major aim of the present study was to investigate effects of the flow r...

This investigation involves recent work on developing membrane distillation (MD) as a novel separation technology for flue gas condensate treatment in combined heat and power (CHP) applications. Flue samples were obtained from municipal solid waste bio-fuel fired CHP facilities tested laboratory-scale air gap MD equipment. Separation efficiencies other water quality parameters measured, the out...

This work focuses on modelling, simulation and process analysis of hybrid membrane separations namely on distillation and pervaporation. Such hybrid process can be applied for the separation of multicomponent azeotropic mixtures without the use of entrainer. Its application is illustrated by the separation of a non-ideal ternary mixture of acetone, isopropanol and water. The extended abstract d...
