February 2016
Our paper on the design of reactive membranes for flow-through dehalogenation is published in Environmental Science: Nano
Crock, C. A.; Tarabara, V. V. Pd and Pd-Au nanocatalysts supported on exfoliated graphite for high throughput dehalogenation by. nanocomposite membranes. Environ. Sci.: Nano. 2016, 3, 453-461.

Research overview

Conceptual illustration of a hierarchical nanocatalyst based on bimetallic (Pd-Au) nanoparticles as the catalyst and exfoliated graphite nanoplatelets as catalyst support. The Pd-Au nanoparticles have core-shell morphology with Au and Pd forming the core and the shell, respectively.

Nano impact statement:
To date, high throughput dechlorination by membrane reactors has not been practical because of the conflicting requirements of high permeate flux and sufficient time for reaction within the membrane. High reactivity catalysts are needed to negotiate the conflicting demands of reactivity and throughput. We report on the design of metallic (Pd) and bimetallic (Pd-Au) catalysts supported on exfoliated graphite nanoplatelets (xGnPs) that enable TCE hydrodechlorination with rate constants up to 81 times higher than those obtained for the commercial Pd/Al2O3 catalyst. Nanocomposite membranes based on these novel catalysts can remove 96% of TCE at the high permeate flux of 47.4 L/m2/h/bar. An inexpensive alternative to graphene, xGnPs as catalyst supports can enable a broad range of other cost-efficient membrane reactions.

November 2015
A paper based on our collaboration with groups of Dr. Merlin Bruening (MSU Chemistry) and Dr. Andre Bénard (MSU Mechanical Engineering) is published in Chemical Engineering Research and Design journal: Ji, P.; Motin, A.; Wenqian Shan; Bénard, A.; Bruening, M. L.; Tarabara, V. V. Dynamic crossflow filtration with a rotating tubular membrane: Using centripetal force to decrease fouling by buoyant particles. Chem. Eng. Res. Des. 2016, 106, 101-114.

Research overview
Force balance in a radial direction on a suspended negatively buoyant particle in a tubular channel with impervious walls (A) and in tubular membranes in the presence of permeate flow (B and C). As the rate of permeation through the membrane increases beyond a critical value, the direction of particle movement reverses from centripetal (B) to centrifugal (C).

Highlights:
- Rotation-induced centripetal forces move low density particles away from the lumen wall
- Fouling by low density particles decreases when rotating a tubular membrane
- Rotation preferentially prevents deposition of particles with large diameters.
- Shear forces dislodge large particles from the cake
- Swirling flow does not fully develop during membrane rotation

 

November 2015
A paper based on our collaboration with Drs. Jia Wei Chew and Anthony G. Fane from the Singapore Membrane Technology Center is accepted for publication in the Journal of Membrane Science: Tummons, E. N.; Tarabara, V. V.; Chew, J.-W.; Fane, A. G. Behavior of oil droplets at the membrane surface during crossflow microfiltration of oil-water emulsions. J. Membr. Sci. 2016, 500, 211-224.

Research overview

Stages of oil-droplet behavior at a microfiltration membrane surface.

Highlights:
- DOTM method is used to visualize oil droplets at the membrane surface
- Fouling stages include droplet clustering, deformation, and coalescence
- Droplets that coalesce to exceed a critical size are removed by shear
- Force balance on a droplet predicts the critical droplet size
- Droplet coalescence and crossflow shear control membrane fouling by oil droplets

 
October 2015

Highlights:
- Changes in permeate flux are mostly determined by calcium concentration and ozone dosage
- Oxidation via different oxidation pathways produces waters with different fouling propensities
- Oxidation by radical species leads to significant hydrophilization of humic acid
- Oxidation by radical species reduces foulant load by mineralizing organics

 

April 2015
Our paper on sacrificial membrane coatings is now published:
Ahmadiannamini, P.; Bruening, M. L.; Tarabara V. V. Sacrificial polyelectrolyte multilayer coatings as an approach to membrane fouling control: Disassembly and regeneration mechanisms . J. Membr. Sci. 2015, 491, 149–158. This is a collaboration with Prof. Merlin Bruening (MSU Chemistry).

Highlights:
- Polyelectrolyte multilayers can serve as sacrificial membrane layers for fouling control
- Surfactants and a pH swing disassemble PEMs by disrupting non-ionic and electrostatic bonds
- PEMs can be regenerated even after fouling by BSA and alginate
- Repeated disassembly/readsorption cycles give stable water permeabilities and selectivities

Research overview

Mechanisms operative in the assembly of polyelectrolyte mutilayer membranes and their attachment to a supporting substrate in two cases: (a) the first polyelectrolyte layer has the same charge as the substrate and (b) the first polyelectrolyte layer has a charge opposite to that of the substrate.

Human adenovirus removal by hollow fiber membranes: Effect of membrane fouling by suspended and dissolved matter is published in the Journal of Membrane Science (J. Membr. Sci. 2015, 482, 120–127). This is a collaboration with the group of Prof. Irene Xagoraraki (MSU Environmental Engineering).

Highlights:
- Adenovirus removal from DI water is less than 2.5 log even for 0.04 µm membranes
- Particulate foulants alone decrease virus removal by 0.04 µm and 0.22 µm membranes
- Humic acid alone increases virus removal by 0.04 µm and 0.22 µm membranes
- Cake formation can increase or decrease virus removal depending on cake properties
- Fouling affects virus removal via pore blockage and cake-enhanced deltaC_virus

 

January 2015
Our paper Amjad, H.; Khan, Z.; Tarabara, V. V. Fractal structure and permeability of membrane cake layers: Effect of coagulation-flocculation and settling as pretreatment steps. Separ. Purif. Technol. 2015, 143, 40-51 is now published. We propose a simple method for estimating fractal dimension of membrane cakes (Dcake) based on permeate flux data and Happel permeability model. We report a correlation, over a range of coagulation-flocculation condition, between Dcake and the fractal dimension of flocs (Dfloc) in the feed suspension. Financial support for Hira Amjad's year-long stay at MSU was provided by a scholarship from the Higher Education Commission and supplementary funding from the National University of Sciences and Technology, Pakistan.

Highlights:
- Inline, direct, and conventional pretreatments for ultrafiltration are studied
- New method for quantifying fractal dimension of membrane cakes is proposed
- Average porosity of membrane cakes increases with filtration time
- Fractal dimensions of flocs and membrane cakes weakly correlate
- Broad range of Dfloc values maps onto a narrow range of Dcake values

Research overview

Illustration of the observed scaling that is indicative of the fractal structure of membrane cakes. Scaling is shown only for the pretreatment condition that corresponds to inline-contact filtration (i.e. coagulation and minimal flocculation)

Our paper on virus concentration has been accepted for publication in the Journal of Membrane Science:
Pasco, E. V.; Shi, H.; Xagoraraki, I.; Hashsham, S. A.; Parent, K. N.; Bruening, M. L.; Tarabara, V. V. Polyelectrolyte multilayers as anti-adhesive membrane coatings for virus concentration and recovery, J. Membr. Sci. 2014, 469, 140–150. This is a collaboration with our MSU colleagues Merlin Bruening (Chemistry), Syed Hashsham (Environmental Engineering), Irene Xagoraraki (Environmental Engineering), and Kristin Parent (Biochemistry and Molecular Biology).

Highlights:
- Anti-adhesive membrane coatings based on polyelectrolyte multilayers are designed
- Anti-adhesive membrane coatings increase pre-elution virus recovery up to 2-fold
- XDLVO virus–membrane interaction energies are computed
- Higher pre-elution recoveries can be attributed to PEM's anti-adhesiveness

Research overview
