Low chromite containing overburden is usually dumped as a waste material during mining of chromite ore. A large quantity of such waste is generated in TISCO chromite mines, India. Since this overburden material contains 20–46% iron, it can be a potential adsorbent for toxic metal ions present in was

This paper deals with the MEDESOL (Seawater Desalination by Innovative Solar-Powered Membrane Distillation System) project, partially supported by the European Commission under the Horizontal Programme “Global Change and Ecosystems (Global 4)”. Despite the advantages of solar membrane distillation (

The microwave (MW) irradiation process has been developed to treat wastewater of methamidophos production. The different oxidants are used as catalyst. A variety of factors affecting MW degradation in the presence of oxidants were studied. The best degradation ratio of methamidophos can be obtained

To explore the novel pervaporation materials, the membranes of hyperbranched polyglycidol (HPG) and hyperbranched poly (amine-ester) (HPAE) were prepared by crosslinking terminal hydroxyl groups with 4,4’-oxydiphthalic anhydride (ODPA) and glutaraldehyde (GA), respectively. Scanning electron microsc

Biofouling potential on NF membranes was investigated in terms of bacterial by-products (BBP) characterizations (e.g., effective diffusivity, zeta potential, and toxicity) and their transport phenomenon. Here, BBP were defined as organic matters derived from microorganisms, such as cell debris, solu

The inhibition action of some ketonic secondary Mannich base derivatives on the corrosion of aluminium in 2M HCl solution was investigated using weight loss and galvanostatic polarization techniques. The inhibition efficiencies calculated from the two different methods are in good agreement. The cor

The corrosion inhibition of aluminium in HCl solution in the presence of exudate gum from Raphia hookeri at temperature range of 30–608C was studied using weight loss and thermometric techniques. The exudate gum acts as an inhibitor in the acid environment. The inhibition efficiency increases with i

The adsorption of C. I. Reactive Red 120 (RR120) on activated oil palm ash (AOPA) was studied in a batch system. The adsorption studies were carried out at different initial dye concentrations (50–600 mg L–1), solution pH (2–12) and temperature (30, 40 and 508C). The experimental data were analyzed

The direct contact membrane distillation (DCMD) applied for the concentration of the primary reverse osmosis (PRO) retentate was presented in the paper. All the experiments were carried out using the self-made hydrophobic polyvinylidene fluoride (PVDF) membranes. The DCMD process (permeate flux and

Fermentation of AFEX-treated and enzymatically hydrolyzed forages and agricultural residues resulted in weak ethanol concentration in broths (maximum 5 g/L). A porous ethanol-selective membrane was evaluated on a model solution (2 wt/wt% ethanol) using pervaporation process. When used under permeate
