Abstract If fine and compressible particle systems need to be separated, the ground layer compaction caused by compacting of filter cake leads high flow resistances. Thin‐film filtration is a suitable method avoid limiting effect cakes. Gas‐impermeable membranes prevent shrinkage cracking, which can occur during demoisturing Titanium dioxide baker's yeast are used as model systems, present in d...

The effect of the pore size distribution on size-resolved filtration efficiency was investigated for two ceramic particulate filters using matter (PM) generated by a spark-ignition direct-injection engine fueled with gasoline. cordierite filter tested had porosity 43%, median diameter 12 ?m, and wide lognormal standard deviation (??) 0.4. aluminum titanate very similar porosity, diameter, thick...

The performance of ion exchange (IX) resin for organics removal from wastewater was assessed using advanced characterisation techniques for varying doses of IX. Organic characterisation using liquid chromatography with a photodiode array (PDA) and fluorescence spectroscopy (Method A), and UV254, organic carbon and organic nitrogen detectors (Method B), was undertaken on wastewater before and af...

Nanofiltration (NF) and tight ultrafiltration (tight UF) membranes are a viable treatment option for high quality drinking water production from sources with high concentrations of contaminants. To date, there is limited knowledge regarding the contribution of concentration polarization (CP) and fouling to the increase in resistance during filtration of natural organic matter (NOM) with NF and ...

The impact of typical anion-exchange flowthrough conditions on the IgG mass loading of an anion-exchange membrane scale-down unit (Mustang Q coin) was investigated. High performance size-exclusion chromatography and multiangle laser light scattering results suggested the presence of a small fraction of IgG aggregates with average radius >100 nm under anion-exchange flowthrough conditions. The s...

The purpose of this paper is an experimental and model assisted investigation of the capabilities of a dewatering system for sewage sludge for decentralised sites. Laboratory and field tests are performed with different initial conditions and the influences of filter medium, initial height, initial total suspended solids, temperature and relative humidity are discussed. The experimental work sh...

In this paper we consider the following property: (⊛ Da) For every function f : R × R −→ R there are functions g 0 n , g 1 n : R −→ R (for n < ω) such that (∀x, y ∈ R)(f (x, y) = n<ω g 0 n (x)g 1 n (y)). We show that, despite some expectation suggested by [Sh 675], (⊛ Da) does not imply MA(σ–centered). Next, we introduce cardinal characteristics of the continuum responsible for the failure of (...

In this study, neat HDPE and HDPE/PE-g-MA/EVA blend membranes were fabricated via thermally induced phase separation (TIPS) method and their fouling behaviors were examined using filtration of BSA protein. Membranes were characterized using FESEM, AFM, ATR-FTIR analyses and porosity measurement. Fouling behavior of membranes was analyzed using the resistance-in-series (RIS), classic and combine...
