Comparing humic acid and protein fouling on polysulfone ultrafiltration membranes: adsorption and reversibility

Journal of Water Process Engineering

Studies of the adsorption of humic acid (HA) in a polysulfone (PSF) porous membrane are described in which a new kinetic trapping mechanism is proposed to explain both performance-based metrics in fouling as well as adsorption isotherm results. The mechanism by which HA at 2 ppm blocks the pores of the PSF is suggested to be due to a dynamic aggregation models, whereas at 700 ppm HA the mechanism of fouling is shown to be quite different.

Abiotic reversible self-assembly of fulvic and humic acid aggregates in low electrolytic conductivity solutions by dynamic light scattering and zeta potential investigation

Science of the Total Environment

The aggregation of humic substances and their interactionwith filtrationmedia (membranes, soils) has implications for our understanding of membrane fouling during water treatment, the facilitated transport of contaminants, and the transport of organicmatter through themicrobial loop. To investigate the aggregation of fulvic and humic acids in low electrolytic conductivity solutions, laboratory studies of simulated environmental water samples as well as actual environmental water samples were examined. Intensity-, volume-, and number-based particle size distributions (PSDs) were obtained by dynamic light scattering. Aggregates were categorized into three ranges, i.e., 10– 100 nm, 100–1000 nm, and N1 μm. Individual biomacromolecules and the aggregates between 10 nm and 1 μm were presumed to be precursors for the formation of a large 5-μm-sized-particle. The self-assembly of the large in- volume, few-in-number, 5-μm-sized particle was observed in real-time and occurred in unfiltered samples and in samples filtered (0.45 μm) at a nominal size one order of magnitude smaller. The supramicrometer-sized particle formed, dissipated, and spontaneously re-formed over turbulent/quiescent cycles in the presence of sodium azide indicating reversible abiotic self-assembly. Zeta potential analyses demonstrated that colloidal stability increased as concentration increased. DLS studies of the environmental water samples were comparable to those of the simulated laboratory samples. The operational range of the instrumentation used in these experiments was 0.6 nm– 6 μm; therefore, aggregates larger than 6 μm may exist in these solutions.

Effects of a dual nanofiller, nano-TiO2 andMWCNT, for polysulfone-based nanocomposite membranes for water purification

Volume 372, 15 September 2015, Pages 47–56

Polysulfone/nano-TiO2/multiwalled carbon nanotube (MWCNT) ultrafiltration membranes with variable nanoparticle (NP) ratios (total filler content at 1%(w/w)) were fabricated by the phase inversion method. Effects of the ratio of TiO2/MWCNT nanoparticles on membrane pore size and morphology, permeation, fouling and rejection of humic acid (HA) were examined. In terms of membrane characterization, scanning electron microscopy images showed that addition of TiO2 (approximately 21 nm) orMWCNTs resulted in finger-like interconnected pores and increased numbers of pores in the surface layer of the membrane. Membranes with a greater amount ofMWCNTs also had an increased pore size, and therefore greater purewater flux.Membraneswith greater TiO2 composition showed lower flux declines in the presence of HA. The membranes inwhich the NPswere combined (e.g., 0.5% TiO2 and 0.5%MWCNT (w/w)) exhibited an optimal balance of performance and synergismin terms of increased flux combined with increased total organic carbon rejection at 2 ppm HA. Additionally, the mechanisms for membrane fouling at 2 ppmHA and 700 ppmHAwere different. The presence of an equivalent mixture of both NPs (e.g., the 0.5%/0.5% mixture) provided the flexibility to improve properties of a single membrane under both types of fouling conditions.

Removal of Acid Black 1 from water by the pulsed corona discharge advanced oxidation method

Journal of Water Process Engineering, Volume 10, April 2016, Pages 1–8

Water pollution is a major global problem. Organic pollutants are one of the major groups of toxic and carcinogenic contaminants that, due to their complex structures, show resistance to biodegradation processes. The pulsed corona discharge (PCD) advanced oxidation technology, with a point-to-point configuration of the electrodes immersed in the aqueous solution, was used for decomposing Acid Black 1 (AB1) as a representative of synthetic organic azo dyes. The effects of electrical field frequencies (60 and 120 Hz) and electrode gap spaces (2, 4 and 6 mm) on decomposition of AB1 were investigated. The largest decomposition achieved was 99.93% with optimal conditions of electrical field frequencies of 120 Hz and an 8 mm electrode gap space. Also, the effect of the catalytic properties of titanium dioxide nanoparticles on the treatment process of the PCD reactor was investigated. Different concentrations of TiO2 NPs (0.075, 0.3, 0.08 and 3 gL−1) were tested. A concentration of 0.08 gL−1 TiO2 was found to be the optimal concentration that increased the dye degradation from 52.62% (with no titanium dioxide nano particles) to 94.14% in 15 min. However, a higher concentration of TiO2 showed the adverse effect and decreased the degradation level of AB1. Finally, the pulsed corona discharge as an oxidation process was compared with the photocatalytic processes of UV, UV/H2O2 and UV/TiO2 in terms of removing AB1 from an aqueous solution, and promising results were reported.
