Evaporation

The growth in population and in the standard of living in the developing countries coupled with inefficient use of water and pollution of available water resources have driven desalination to be a major source of fresh water for both domestic and industrial purposes. The potential environmental impac

At “Debiensko” Desalination Plant salt crystallizer is supplied with untreated brine concentrated by RCC evaporation method that results in high energy consumption and huge amount of post-crystallization lye. Nanofiltration pre-treatment of coal-mine brine was then considered to improve plant outcom

A semi-analytical approach was presented to study the transient heat transfer of a single volatile drop evaporation in an immiscible liquid with bubble nucleation inside the drop. The solution was based on the energy equation included both convection and conduction heat transfer from the continuous

Canesis Network Limited, in conjunction with Keratec Limited, has developed a patented process for the chemical extraction of soluble keratin proteins from wool. This extraction process results in the generation of several proteinrich streams, including a dilute aqueous based peptide stream. This pe

The AQUASOL-Enhanced Zero Discharge Seawater Desalination using Hybrid Solar Technology (EVK1CT2001-00102) project is one more attempt at using solar energy for water desalination, improving the economics and the environmental performance of a MED desalination plant. Within the project, an advanced

Different theoretical and experimental studies carried out in the field of solar distillation with green-house effect, have shown that global efficiency of a simple solar still are affected by physical and building parameters, especially by the difference of temperature between the evaporation surfa

The evaporation of a thin liquid film flowing down on the internal face of one plate of a vertical channel is studied. The wet plate is subjected to a uniform heat flux while the second plate is taken isothermal and impermeable. The governing equations in the liquid and in the gas regions with the b

Solar drying, an energy-saving process, is an efficient food conservation solution for countries that often have only sun as an energy source. Decreased energy requirements for a drying and improved dewatering process result from lower moisture fraction. This investigation focuses on the study of wa

Concentrated must is a natural sweetener in wine production, and in addition, it is a vitamin- and aroma-rich drink. In this study the basis of a complex membrane process was developed for must concentration. Modeling the experimental results and using recent economic data, the optimal process param

A test rig was designed and fabricated in this project to study the heat transfer of falling film flow on a doubly fluted plate. Parametric studies were performed to test the thermal performance based on the measured data. The effects of the temperature difference and feed water flow rate were studi
