This work describes the determination of carboxylic acid overall mass transfer coefficients in a circulating flow experimental set-up composed of a flat plate dialyzer and a concentrate reservoir. Sodium acetate and sodium propionate were used as the sodium salts of carboxylic acids. By referring to

This study establishes a mathematical model that describes the vapor sorption level as a function of its activity in poly(dimethyl siloxane) (PDMS) membrane in multi-component systems. The investigated vapors included polar (methanol, water) and non-polar (m-xylene, toluene, and isopentane) permeant

This work investigated the role of fertilizer application rate on phosphorus (P) transport and loading to Lake Uluabat in Turkey. For this purpose ArcView Interface of Soil and Water Assessment Tool 2000 (AVSWAT) was used. Results showed that when the fertilizer amount applied to agricultural lands

This work discusses the applicability of the DSPM with dielectric exclusion (DSPM-DE) to describe nitrate rejection of a high rejection nanofiltration membrane (NF90 from Dow-Filmtec). In particular, the limitations of the application of the model to relatively high feed concentration and different

The release of non-condensable (NC) gases, essentially carbon dioxide, oxygen and nitrogen, from the evaporating brine in desalination distillers notably affects the heat transfer for condensation, the energy consumption, the performance and the material life span of the distillers. A better knowled

The release of CO2 in multiple-effect distillers has scarcely been investigated and little has been published about it. There is no approach available to reliably predict the release rates in individual stages and the effects of influencing parameters. Until now the dimensioning of the design ventin

Design and operating characteristics are analyzed for two pilot scale reverse osmosis plants. The first plant is installed in Sharjah to desalinate brackish water for a small community. The second plant is installed in Qatar to test the feasibility of desalting high-salinity seawater for irrigation

The performance of multijunction amorphous silicon cells has been investigated for outdoor solar spectral radiation, using long term measurement for existing data at CREST, Loughborough University. It is a further study of the solar system, destined to analyze the outdoor performance of the amorphou

In this paper, we investigate using an adaptive radial basis function (RBF) network with infinite impulse response (IIR) filter in order to find a suitable model for sizing coefficients of the stand-alone photovoltaic (PV) systems, based on minimum of input data. These sizing coefficients allow to t

Laboratory experiments and model calculations were performed to elucidate the fundamental interactions that control organic fouling in reverse osmosis (RO) processes. Bovine serum albumin and alginic acid were selected as model aquatic organic macromolecules (organic foulants). An extended Derjaguin
