One of the key issues in membrane technology is to avoid fouling which is formed on the membrane surface. To get over this trouble, the use of a patterned surface was suggested as a way to reduce fouling. In this report, both the experimental and numerical studies were performed with a prism patterned membrane system. In our experiments, we observe the local distribution of microbials; more fou...

• The coatings consist of pre-modified SiO 2 nanoparticles with high-degree densification. exhibit stable superamphiphobicity under prolonged immersion mixed oils. performance is over 20 times more immersion-durable against pre-existing surfaces. Coated impellers achieve up to 65% contamination-resistance accelerated testing. Superamphiphobic have attracted tremendous interest from both academi...

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...

Graphene oxide/Ag nanoparticles (Ag/GO) was prepared and employed to synthesize antifouling polyethersulfone (PES) mixed matrix membranes. The performance of the membranes was evaluated in terms of flux, hydrophilicity and anti-biofouling properties. With increment of the Ag/GO from 0 to 0.1 wt.%, the pure water flux increased from 24.7 up to 54.1 kg/m2 h. The flux recovery ratio (FRR) of the m...

In this study, the ultrafiltration membrane for humic substance removal was prepared by blending polysulfone with a high concentration of PEG400 as additives. The influences of the additive to the fouling resistance capability and humic substances rejection of the polysulfone membrane were investigated. The addition of 35%wt of PEG400 concentration improved the pure water flux up to 200, but re...

Blooms of blue-green algae such as Microcystis aeruginosa in aquatic systems can result in substantial algal organic matter (AOM) entering downstream water treatment facilities. It has been demonstrated in a number of recent studies that AOM can cause severe fouling of low pressure membrane filtration systems [1, 2]. In this work the distribution of the foulant on a ceramic microfiltration memb...

Membrane fouling problem is one of the most crucial issues which restricts the development of MBR and is, therefore, the prime research topic for many researchers worldwide. Anaerobic MBRs offer interesting perspectives as a potential solution for the treatment of wastewaters under extreme conditions, e.g. high temperature and/or high salt content, However, the research on membrane fouling of A...

As part of an environmental observation and forecasting system, sensors deployed in the Columbia RIver Estuary (CORIE) gather information on physical dynamics and changes in estuary habitat. Of these, salinity sensors are particularly susceptible to biofouling, which gradually degrades sensor response and corrupts critical data. Automatic fault detectors have the capability to identify bio-foul...

The mechanisms regarding the influence of dissolved organics in papermaking whitewater together with metal ions on the fouling of an ultrafiltration (UF) membrane were studied in this paper. A series of experiments were carried out to characterize the organic matters’ size and membrane flux. The associated fouling mechanism was investigated using the modified Hermia empirical model, resistance ...

Fouling behaviour and its impact on the rejection of trace organic contaminants (TrOCs) by forward osmosis (FO) were investigated.Membrane fouling was simulated using humic acid and colloidal particles asmodel foulants at different initial permeatewater fluxes.Water flux declinewas insignificant at an initial permeate flux of 9 L/m2h and the fouling layerwas loose and fluid-like. By contrast, t...
