Abstract:
Molasses is a dark brown by-product of sugar production and refining, rich in sugar, vitamins, and salts. The dark coloured pigments are mainly melanoidins, which are produced through the Maillard reaction between amino acids and sugar. Molasses is widely used as an inexpensive source of sugar in biorefineries to produce a range of products including baker’s yeast. Due to adsorption of melanoidins, Baker’s yeast has a dark colour and needs to be washed in several steps to be acceptable to the market. This washing increases the volume of wastewater, which causes major wastewater treatment i

Abstract:
<p>Desizing wastewater is largely responsible for the chemical oxygen demand (COD) load in the textile industry wastewater. A larger portion of COD comes from degraded starch in desizing wastewater. Removing the starch from the wastewater by an ultrafiltration process may reduce the environmental problem caused by the textile factory. If the treatment is made in such a way that all starch components are removed from the wastewater, the treated water can be reused by the factory. If the starch in the concentrate is stable, it can also be reused as a sizing agent. This will give the factory an e

The influence of the physicochemical conditions on the permeation rate in dead-end and cross flow ultrafiltration of protein dispersions is investigated.

The calculations are expressed in terms of an osmotic pressure which accounts for the multiparticle electrostatic interactions, dispersion forces and configurational entropy.

Exploitation of this size difference to remove difficult to separate fatty acids from aqueous solutions by ultrafiltration was investigated in this study.

The development of quantitative predictive models is of great significance for the successful application of membrane separation processes in the process industries.

None of the approaches could predict colloidal ultrafiltration rates in the intermediate size range of 5 to 500nm. This is due to interparticle interactions, especially electrostatic interactions which play an important role and which have been widely neglected or even overlooked by many membrane sci

The mass of five proteins (Bovine serum albumin (BSA), casein, lysozyme, ovalbumin and pepsin) adsorbed to five different membrane materials (of various hydrophobicities) was quantified using a static system and analysed to establish any trends. Comparing the results from the five membranes it seems that there were no obvious trends between the protein masses adsorbed indicating that it may not be just one aspect of protein structure that is important in the adsorption process. Many investigations have indicated that the protein may undergo a conformational change during the adsorption process

Since much of the solute is within the micelles, a membrane with a molecular weight cut off (MWCO) much larger than the molecular weight of the solute is used.
