Removal of lactate from acid whey using nanofiltration

Removal of textile dye from aqueous solutions by nanofiltration process

The feasibility of employing nanofiltration (NF) in the decolorization of ionic (direct blue 86) and nonionic (disperse blue 56) dye aqueous solutions was investigated. The effects of feed concentration (60- 180 mg/l), pressure (0.5- 1.1 MPa) and pH (6- 10) were studied. Experiments were performed in a laboratory- scale set up by using a TFC commercial spiral wound polyamide nanofilter. The res...

Potential of Nanofiltration for Phosphate Removal from Wastewater

Experimental investigations were conducted to evaluate the performance 01 n"nofillration fOr tertiary level phosphate removal from wastewater. A flat sheet type Oesal-5 thin 5lul nanofi)tration membrane in a plate and frame module, was IJsed. The inIIuc.nce of pressure. initial feed roncentntion, competing compounds, on nanoflllration performance were determined. TIlecxperimelltal study range o...

Production of L(+) Lactic Acid using Lactobacillus casei from Whey

The aim of this work was to study the fermentation of whey for the production of L(+) lactic acid using Lactobacillus casei. The effect of different process parameters such as pH of the medium, temperature, inoculum size, age of inoculum, agitation and incubation time was monitored to enhance the lactose conversion in whey to L(+) lactic acid. Fermentations were performed without any pH control...

Nanofiltration as a Tertiary Treatment for Phosphate Removal from Wastewater

Influence of Operating Variables on Performance of Nanofiltration Membrane for Dye Removal from Synthetic Wastewater Using Response Surface Methodology

The textile industry is a water intensive industry that produces a large amount of highly colored wastewater that must be properly treated before disposal or reuse. In the present study, to verify the possibility of reusing textile wastewater with nanofilteration (NF), an attempt was made to treatment of synthetic reactive dye aqueous solution by commercial nanofiltration membrane. Experiments ...
