Evaluation of Nanofiltration for the Purification

ثبت نشده
چکیده

This study focuses on a possible elimination of glucose from a sodium lactate fermentation broth by nanofiltration (NF). The results obtained with single-solute solutions indicate that glucose is clearly more retained that sodium lactate. Nevertheless, glucose retention strongly decreases when the two solutes are present in the same solution and the separation becomes unachievable. Such a incidence of a solute on another in NF has rarely been reported before.

Organic solvent nanofiltration for microfluidic purification of poly(amidoamine) dendrimers.

A nanofiltration method has been developed in a microfluidic format for the continuous-flow pressure-driven purification of half-generation poly(amidoamine) (PAMAM) dendrimers, a family of macromolecules characterized by highly branching structures radiating from a central core, without additional solvents or buffers. An organic solvent resistant nanofiltration membrane, STARMEM 122, has been f...

Successful Integration of Membrane Technologies in a Conventional Purification Process of Tannery Wastewater Streams

The aim of this work is to design and integrate an optimized batch membrane process in a conventional purification process used for the treatment of tannery wastewater. The integration was performed by using two spiral wound membrane modules in series, that is, nanofiltration and reverse osmosis, as substitutes to the biological reactor. The membrane process was designed in terms of sensible fo...

Performance Evaluation of Hybrid Coagulation/Nanofiltration Process for AT-POME Treatment

The presence of lignin and its degraded products such as tannin and humic acids is the main reason causing the aerobically-treated palm oil mill effluent (AT-POME) to display colour at the point of discharge. In this work, a hybrid method is developed to treat the AT-POME sample that was conventionally treated by biological method. This hybrid method combines coagulation and nanofiltration (NF)...

Evaluation and comparison of affinity chromatography and precipitation– based methods on purification of recombinant streptokinase

Background: Increase of protein purity is a serious challenge in the production of recombinant therapeutic proteins. For this purpose, several strategies have been employed to purify the target protein, among which the affinity chromatography-based purification methods and tagged proteins such as Ni-NTA are common and but costly. Therefore column-free purification techniques, such as using elas...

Biofilm recruitment under nanofiltration conditions: the influence of resident biofilm structural parameters on planktonic cell invasion

It is now generally accepted that biofouling is inevitable in pressure-driven membrane processes for water purification. A large number of published articles describe the development of novel membranes in an effort to address biofouling in such systems. It is reasonable to assume that such membranes, even those with antimicrobial properties, when applied in industrial-scale systems will experie...
