“…It can then be concluded that the kaolin MF membrane mainly retained the suspended matter (melanin) while the soluble fraction consisting of organic (macro) molecules and salts pass through the membrane. Such results are in agreement with the values given in the literature for inorganic MF membranes in similar applications (waste water treatment) [18,29,39,43].…”

“…Recently, the development of low cost ceramic membranes based on natural materials such as apatite powder [13], natural raw clay [14][15][16], graphite [17], phosphates [18,19], dolomite, kaolin [20][21][22][23][24] and waste materials such as fly ash [25][26][27][28][29], appeared as an efficient solution to treat waste water at a low cost. The properties of the ceramic membranes are mainly determined by their composition, the pore-former content and the sintering temperature.…”

The focus of this work is to assess the quality of porous membranes prepared from naturally occurring kaolin clays and to evaluate the performance of tubular ceramic membranes treating integrated raw effluents from seafood industry. This material has been chosen due to its natural abundance, its non-tox IntroductionWater pollution is one of the most important crises in modern times because water is the most important basis of life. There is much current interest in the application of microfiltration and ultrafiltration membranes in separation procedures because of their potential for the treatment of large quantities of wastewater [1][2][3][4][5]. This is a successful way to solve water pollution crisis and to maintain the environment wellness.The use of ceramic membranes has many advantages such as high thermal and chemical stability, pressure resistance, long lifetime, good resistance to fouling, and ease of cleaning [6][7]. Unfortunately, ceramic membrane fabrication, even though commercially available, still remains highly expensive from a technical and economic point of view due to the use of expensive powders such as alumina [8][9][10], zirconia, titania and silica [11,12].Recently, the development of low cost ceramic membranes based on natural materials such as apatite powder [13], natural raw clay [14][15][16], graphite [17], phosphates [18,19], dolomite, kaolin [20][21][22][23][24] and waste materials such as fly ash [25][26][27][28][29], appeared as an efficient solution to treat waste water at a low cost. The properties of the ceramic membranes are mainly determined by their composition, the pore-former content and the sintering temperature.MF is a membrane process for concentration, purification, and fractionation in diverse fields such as food, textile, pharmacy, chemical, paper, and leather industries. MF is often used to remove particles, microorganisms, and colloidal materials from suspensions [30][31][32].Fouling would reduce productivity and potentially shorten membrane life. To understand the mechanisms of fouling, some researchers proposed various models to analyze and predict the flux decline behavior during filtration of macromolecular solutions, among them the resistance-in-series model. According to this model, the flux decline is due to the combined effects of irreversible membrane fouling which is not easy to remove [33,34] but with reversible fouling, rinsing with clean water can solve the problem. The main factors that influence fouling are the physicochemical properties of the membrane, feeding solution and operating conditions.

“…It is important to notice that fouling is not very important since the flux decline did not exceed 15% for the different pressures used. This is a specific behavior of the UF membrane compared to MF membrane that showed generally an important decrease of flux due to pores blocking by retained particles [26,21]. Moreover, it can be observed that permeate flux increases with TMP from 3 bar to 5 bar and then becomes almost pressure independent for a pressure up to 5 bar.…”

“…This includes woven fabric and mesh (e.g., Kiso et al, 2000;Chang et al, 2001Chang et al, , 2007Wu et al, 2005) as well as ceramic membranes prepared from naturally occurring or waste materials (e.g. Nandi et al, 2009;Jedidi et al, 2009). The concept of employing low-cost membranes made from waste material in decentralised systems is a step towards sustainability and is therefore of importance in developing countries.…”

This paper presents the initial findings of field testing of 2 low-cost membrane filters, viz. 30 μm polymeric mesh and 2-6 μm macroporous waste-ash based ceramic filter, in a submerged membrane bioreactor (MBR) employing batch anoxic and aerobic conditions. The influent was raw wastewater from a residential complex located near Delhi, India. The results indicated that the ceramic filter was able to operate for longer periods without cleaning; however, there is a limit to the transmembrane pressure it can withstand. The suspended solids retention was high with both filters (average of 96%). Moderate reduction in chemical oxygen demand (COD), total nitrogen (NH 4 + ) and total phosphorus (PO 4 3-) was achieved. The improvements in operation required in such systems are also underlined.
