The Canadian Journal of Chemical Engineering, EarlyView.Abstract The waste activated sludge high‐rate (WASHR) process, developed in our previous study, is used for septic wastewater treatment. This high‐rate contact stabilization pre‐treatment uses typical waste streams found in wastewater treatment plants to reduce a portion of the loadings on the main treatment trains.

Spatially resolved 23Na magnetic resonance dispersion measurement in porous media
The Canadian Journal of Chemical Engineering, EarlyView.Quantitative 23Na MRI was employed to analyze dispersion in realistic core plug samples and was compared with the conventional breakthrough curve. 23Na MRI provided a more effective aassessment of core plug heterogeneity than the conventional method. Abstract Tracer tests are widely used in the petroleum industry to assess reservoir core plugs, relying

SiC/Si ceramic hollow fibres: A new approach to Chlorella vulgaris biomass harvesting
The Canadian Journal of Chemical Engineering, EarlyView.Abstract Efficient harvesting of microalgae is a critical challenge for the viability of biorefineries, requiring technologies that combine high selectivity, low cost, and scalability. The current work evaluated the performance of an asymmetric hollow fibre ceramic membrane (HF‐SiC70Si30), fabricated by phase inversion and sintered at 1250°C, in the ...

In this chapter, the probabilistic porous network model is employed to establish a fully analytical equation for the relative hydraulic conductivity of soils. From this approach, a parameter accounting for the proportion of pores of different sizes forming continuous paths of saturated elements between the boundaries is used to compute the ...

The hydraulic conductivity of Matrigel™
Biorheology: The Official Journal of the International Society of Biorheology, 2007In this study, we measured the specific hydraulic conductivity (K) of Matrigel™ at 1% and 2% concentrations as a function of perfusion pressure (0 to 100 mmHg) and compared the results to predictions from two models: a fiber matrix model that predicted K of the gel based upon its composition, and a biphasic model that predicted changes in K caused by ...

Hydraulic conductivity of polymer matrices
Biophysical Chemistry, 1989We demonstrate that the chondroitin sulfate proteoglycan exhibits enhanced sensitivity to the flow of water compared to other macromolecules which is in accord with their functional role in conferring compressive resistance to cartilage. In order to understand factors that may contribute to its low hydraulic conductivity, a comparative study of ...

Hydraulic conductivity of compacted zeolites
Waste Management & Research: The Journal for a Sustainable Circular Economy, 2013Hydraulic conductivities of compacted zeolites were investigated as a function of compaction water content and zeolite particle size. Initially, the compaction characteristics of zeolites were determined. The compaction test results showed that maximum dry unit weight (γdmax) of fine zeolite was greater than that of granular zeolites.
