Special Issue Information

Dear Colleagues,

Through our engagement in experimental and theoretical research of membranes and membrane processes, we noticed that, despite its 60-year history in the field of membrane science, the problem of the scaling phenomenon still has no satisfactory solution. In industry, applying membrane methods requires the pretreatment of processed solutions when there is a risk of scaling. Solutions are rid of multiply charged ions by directly introducing complexing agents and scale inhibitors (antiscalants) during processing or the pretreatment of solutions. However, the addition of chemicals inevitably increases operating costs, and these chemicals can be sorbed onto membranes, which leads to fouling.

In the long term, scaling inside and on the surface of membranes leads to a decrease in their permeability, shortens their lifespan and increases the energy consumption and cost of the final product, mainly because the electrodialyzer must be washed and the membranes replaced.

Due to the vital importance of developing methods to fight membrane scaling, we are pleased to invite you to submit your contributions to this Special Issue of the Membranes journal, entitled “Recent Advances in Fighting Membrane Scaling: Experiment, Simulation and Industry Advances”.

The aim of this Special Issue is to gain an understanding of current methods for fighting membrane scaling, which may include, but are not limited to, the following:

– Membrane modifications;

– Application of special current or hydrodynamic modes;

– Expedient use of complexing agents and scale inhibitors;

– Mathematical modeling of systems prone to scaling.

We would be happy to answer your questions and look forward to receiving your contributions.

The features of organic fouling have been revealed for highly basic anion exchange membranes during prolonged electrodialysis in solutions containing the aromatic amino acid tyrosine. With increased operation time when using MA-41 heterogeneous membranes in tyrosine solution, an increase in hydrophobicity and roughness characteristics of the material surface is detected. A reduction in tyrosine flux through the membrane occurs which is caused by its pores plugging and deposition of the amino acid at the membrane surface induced by tyrosine adsorption and local supersaturation of the solution in the membrane phase. The long-term contact of the anion exchange membrane with a solution of tyrosine leads to some structural changes in the anion exchange material. An accumulation of the studied amino acid with phenolic fragment and tyrosine oxidation products (DOPA, DOPA-quinone) is found and confirmed by IR- and UV-spectroscopy techniques. The organic fouling is accompanied by an increase in density and a decrease in moisture content of the studied membrane. A comparative analysis of the chemical and electrochemical cleaning results for fouled samples of the MA-41 membrane demonstrates a partial restoration of the material transport characteristics using electrochemical cleaning in the intensive current mode of electrodialysis. The best efficiency of regeneration is reached when carrying out chemical cleaning with a solution of hydrochloric acid, providing almost complete restoration of the membrane characteristics.

Adsorption of polymeric inhibitor molecules to calcium carbonate crystal surface was investigated. Inhibiting efficiencies of phosphonic acid-based antiscalants are dependent on the amount of adsorbed material on the growing crystal surface. A strong antiscalant even at a small dose provides the necessary rate of adsorption. Comparison of two phosphonic-based antiscalants was made both in laboratory and industrial conditions. A distinguishing feature of the strong antiscalant is the presence of aminotris (metylene-diphosphonic acid) ATMP. Experimental dependencies of antiscalant adsorption rates on the antiscalant dosage values were determined. Emphasis is given to the use of nanofiltration membranes that possess lower scaling propensities. Modernization is presented to reduce operational costs due to antiscalant and nanofiltration membranes. The main conclusion is that control of scaling should be implemented together with the use of nanofiltration membranes. Full article

Anion-exchange membranes modified with a polyquaternium-22 (PQ-22) polymer were studied for their use in electrodialysis. The use of PQ-22 for modification makes it possible to “replace” weakly basic amino groups on the membrane surface with quaternary amino groups. It was found that the content of quaternary amino groups in PQ-22 is higher than the content of carboxyl groups, which is the reason for the effectiveness of this polymer even when modifying Ralex AHM-PES membranes that initially contain only quaternary amino groups. In the case of membranes containing weakly basic amino groups, the PQ-22 polymer modification efficiency is even higher. The surface charge of the modified MA-41P membrane increased, while the limiting current density on the current-voltage curves increased by more than 1.5 times and the plateau length decreased by 2.5 times. These and other characteristics indicate that the rate of water splitting decreased and the electroconvective mixing at the membrane surface intensified, which was confirmed by direct visualization of vortex structures. Increasing the surface charge of the commercial MA-41P anion-exchange membrane, reducing the rate of water splitting, and enhancing electroconvection leads to mitigated scaling on its surface during electrodialysis.
