Isogai, Esti atio of ole ula diffusi it i li uid phase s ste s the Wilke- Cha g e uatio. The main cost is in the initial investment. As a result, the higher the tortuosity value, the lower the permeate flux.
Higher porosity membranes have a larger evaporation surface area and therefore higher permeated flux and lower conductive heat loss. These gases remain in the membrane pores and obstruct the way vapor molecules and reduce their momentum towards the condensation side. Ba at, Desali atio sola po e ed e a e distillatio s ste s, Desalination, vol. Easily read eBooks on smart phones, computers, or any eBook readers, including Kindle.

Mohamed Khayet Souhaimi Takeshi Matsuura. Vacuum membrane distillation, temperature and concentration polarization, heat and mass transfer. Membrane porosity refers to the void volume fraction of the membrane defined as the volume of the pores divided by the total volume of the membrane. Modern membrane engineering is critical to the development of process-intensification strategies and to the stimulation of industrial growth.
He has also authored and co-authored six books and edited eight books. By using our website - scrolling this page, clicking a link or closing this banner, means you agree to this. The thermal conductivities of most hydrophobic polymers are close to each other. The Memsys process has five effect stages to form one module.
Xiao, E pe i e tal a d theo eti al research on N-methylpyrrolidone concentration by vacuum membrane distillation using pol p op le e hollo fi e e a e, J. Institutional Subscription.

Sorption on the membrane material is also possible. Re es, Modelli g of ate t a spo t i os oti distillatio usi g as et i e a e, J.
Sensitivity analysis and Taguchi application in vacuum membrane distillation. The subscripts sv and a denote the solvent and the solute, respectively. Thermal collectors are used to harvest thermal energy from the sun and heating up the heat transfer fluid fresh water.
However, once the system is operational, it is extremely inexpensive to maintain and the energy has minimal or even no cost. Although the three modules have different packing densities, the flux both modelling and experimental results was very similar under the same conditions. Recent Developments and Breakthrough Products.
The recipient will get an exact copy of the products in your cart. The objective function was established to minimize water production cost by investigating four variables, including feed temperature, hollow fiber length, volume flow rate and vacuum pressure. Please select a region, state or province.
Future Directions in Membrane Distillation Index. Therefore, the experimental pressure on the permeate side was not constant between experiments and this affected the resultant driving force across the membrane as well as the temperature. These membranes vary in terms of pore size, thickness, polymer, which in turn effect permeability, chemical compatibility, inteligencia emocional pdf gratis and water entry pressure.
Thank you for posting a review! You're using an out-of-date version of Internet Explorer. Share your review so everyone else can enjoy it too. Similarly, reduced membrane thickness offers less resistance to the vapor transport through the membrane, but also increases the conduction losses through the membrane material. The system is stand-alone system which does not need external energy for its operation.
The process is deemed suitable to operate in conjunction with solar energy for small capacities. Acrylic Chemical Resistance.
Free Shipping Free global shipping No minimum order. As such, academic theoreticians and experimentalists around the world have studied it. The fresh water is circulated between the collector and thermal tank.
Membrane distillation was considered as a process that would operate with a minimum external energy required. Membrane Distillation for Desalination and Other Separations. Nevertheless, operational cost will definitely increase due to external condensation system. Remember me on this computer. This information will also be stored by Sterlitech until you revoke your consent, which you can do at any time.

By sending this form you agree that the entered data will be used for the purpose of processing your request. The trans-membrane temperature difference results in vapor pressure difference as a driving force.
To asze ska, Heat t a spo t i the e a e distillatio p o ess, Membr. The battery is used to store electrical energy for extended operation of the desalination system after sunset or at low solar irradiation level. We are always looking for ways to improve customer experience on Elsevier. On the permeate side, a vacuum pump sweeps away the vapor components and reduced their partial pressure, thus creating the driving force for the mass transfer.
