The use of solar energy in thermal desalination processes is one of the most promising applications of the renewable energies. Solar desalination can either be direct; use solar energy to produce distillate directly in the solar collector, or indirect; combining conventional desalination techniques,

A series of polyimide/vanadium pentoxide (PI/V2O5) hybrid film has been successfully fabricated through the in situ formation of V2O5 within a polymer matrix by sol–gel process. The polyamic acid (PAA) is prepared from 4,40 -diaminodiphenyl ether (ODA) and 3,30 ,4,40 -benzophenonetetracarboxylic anh

The aim of the present work is to establish a systematic approach in the range of characterization of commercial nanofiltration (NF) and low pressure reverse osmosis (LPRO) membranes materials for a better help to the users. We developed two sorts of characterizations: (i) first physico-chemicals in

The fouling characteristics of ultrafiltration membranes used in drinking water were investigated when used alone and when used in an integrated biofilter-membrane system to treat a humic-acid laden solution. Membrane strands from sacrificial modules operating in parallel with bench-scale modules we

In this study, the performance of sequencing batch reactor (SBR), aerobic membrane bioreactor (AMBR), anaerobic-oxic membrane bioreactor (AOMBR) and AOMBR/RO processes treating the synthetic textile dyeing wastewater (Reactive Black 5) was investigated and compared. After more than 2 year process op

Polydimethylsiloxane composite membrane was employed for the separation of phenol and sodium chloride in synthetic wastewater. The major operational parameters affecting phenol transfer through this composite membrane were screened by the orthogonal array and range analysis. The results showed that

Carbon dioxide is one of the global warming gases. Utilization of a sustainable energy is one of the effective technologies for the mitigation of CO2 accumulation in the atmosphere. If renewable energy can be used for methane synthesis, H2 is converted to methane by reducing CO2. We investigated the

The objective of this study was to examine the removal of arsenic from groundwater by a laboratory scale electro-ultrafiltration (EUF) system. Two groundwater samples taken from I-Ian County located in the northeastern part of Taiwan were studied. These well waters were selected based on their As(II

Nanofiltration membrane bioreactor (NF-MBR) was proposed to provide quality effluent free of virus and most large organic substances. The dissolved organic matter (DOM) in soluble microbial products (SMP), loosely bound extracellular polymeric substances (LBEPS) and tightly bound extracellular polym

A pilot plant scale hollow fiber membrane system was developed for the removal of dissolved oxygen from boiler feed water via vacuum degassing process. Feed water was introduced to the shell side; a vacuum was applied to the lumen side of the hollow fiber. The effects of water flow rate, vacuum leve
