“…Mueller et al [7] observed less hydraulically irreversible fouling on a TiO 2 membrane with Al 2 O 3 support than on a polyethersulfone (PES) polymeric membrane during surface water filtration, probably due to less biopolymer fouling on the TiO 2 membrane as determined by liquid chromatography with an organic carbon detector (LC-OCD). Hofs et al [6] also reported less hydraulically irreversible fouling on ceramic membranes in comparison with a polymeric one, and they attribute this to a higher volume/area ratio on the tested ceramic membranes modules resulting in different hydraulic conditions. When filtrating algae organic matter (AOM) released from Microcystis aeruginosa, a dominant cyanobacterium in reservoirs or lakes during seasonal algae bloom, the hydrophilic fractions in AOM contribute to the hydraulically irreversible fouling on a ceramic membrane (ZrO 2 -TiO 2 ) [8], while the hydrophobic fractions were mainly found in the irreversible fouling layer of a polymeric membrane (PES) [9].…”

“…Ceramic membranes can be made to have fairly uniform pores in size, but defects, if occur in the ceramic membranes, will ruin the permeate water quality [4]. It is also reported that ceramic membranes offer a better permeate water quality and exhibit a lower trans-membrane pressure (TMP) increase than polymeric membranes due to their higher porosity and more uniform pores [5,6]. However, fouling on ceramic membranes, especially the hydraulically irreversible fouling, can still be severe, with consequences for increased operational costs and energy consumption.…”

Please note that during the production process errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain. irreversible fouling, is still a critical aspect affecting the operational cost and energy consumption in water treatment plants. In this study, four ceramic membranes with pore sizes or molecular weight cut-off (MWCO) of 0.20 μm, 0.14 μm, 300 kDa and 50 kDa were compared during natural surface water filtration with respect to hydraulically irreversible fouling index (HIFI), foulant composition and narrowing of pore size due to the irreversible fouling. Our results showed that the hydraulically irreversible fouling index (HIFI) was proportional to the membrane pore size (r 2 =0.89) when the same feed water was filtrated. The UF membranes showed lower HIFI values than the MF membranes. Pore narrowing (internal fouling) was found to be a main fouling pattern of the hydraulically irreversible fouling. The internal fouling was caused by monolayer adsorption of foulants with different sizes that is dependent on the size of the membrane pore.

“…Prior to further chemical cleaning, the normalized flux was measured with DW to determine chemically reversible fouling. [10] The CIP procedure was determined according to the literature [17,[21][22][23][24] and some preliminary trial-and-error tests with different chemical agents, concentrations and temperatures. After the CIP process, normalized flux with DW was observed again and any remaining membrane blockage was considered as chemically irreversible fouling.…”

Textile wastewaters are rated as one of the most polluting in all industrial sectors, and membrane separation is the most promising technology for their treatment and reuse of auxiliary chemicals. This study evaluates the performance of three types of tubular ceramic ultrafiltration membranes differing by mean pore size (1, 2 and 500 kDa) treating textile mercerization wastewater from a textile mill at different operating conditions: cross-flow velocity (CFV) and temperature. Acceptable results were obtained with 1 kDa ceramic membrane, with rejection efficiencies 92% for suspended solids, 98% for turbidity, 98% for color and 53% for total organic carbon at 20°C and 3 m s −1 CFV. Highest fouling effect was observed for 500 kDa membrane and lowest CFV. According to the observed results, 1 kDa membrane could be used for the treatment of wastewater from the textile mercerization process in terms of permeate quality. ARTICLE HISTORY

“…However, the polymeric membranes widely adopted in wastewater treatment applications display relatively low thermal and chemical resistance. There has been an upsurge of interest in ceramic membranes for the treatment of high-strength wastewater, for which polymeric membranes are not suitable [4,5]. Ceramic membranes consisting of metal oxides usually exhibit high membrane porosity, membrane permeability, and narrow distribution of the membrane pore size.…”

Photocatalytic ceramic membranes have attracted considerable attention for industrial wastewater treatment. However, morphological control of the membrane surface to improve its photocatalytic reactivity for the degradation of organic pollutants remains a challenge. Herein, we report a new nanostructured TiO 2 /Al 2 O 3 composite ceramic membrane prepared from a poly(oxyethylene methacrylate) (POEM) template through a sol-gel method and its photocatalytic performance in the treatment of a model dye compound. The POEM polymeric template allowed the homogeneous distribution of catalytic sites, i.e., the TiO 2 layer, on the Al 2 O 3 membrane surface, resulting in improved organic dye degradation along with effective fouling mitigation. The immobilization of a TiO 2 layer on the Al 2 O 3 membrane support also significantly enhanced the membrane adsorption capacity toward dye organic compounds. An organic removal efficiency of over 96% was achieved with the TiO 2 /Al 2 O 3 composite membrane under Ultraviolet (UV) irradiation. In addition, the self-cleaning efficiency of the TiO 2 /Al 2 O 3 composite membrane was remarkably improved by the degradation of organic foulants on the membrane under UV illumination.
