“…The relative goodness of the prepared UF kaolin membranes for the oily wastewater treatment was assessed by comparing its performance with ceramic Titania UF membrane (150 kDa) previously tested by Aloulou et al [ 90 ]. All these ceramic membranes displayed similar oil rejection higher than 99%, and a high removal of heavy metals of up to 95%.…”

“…Indeed, Saudi Arabia, and more particularly the central region of “Ar Rass”, has been struck for years by the scarcity of water and wishes to examine all the technically simple and financially affordable solutions to reuse water resulting from certain industries. Therefore, we have jointly developed studies to investigate the treatment of different wastewater [ 16 , 90 , 185 ], and especially water from the textile industry or from car washes, in order to make it reusable (e.g., for household tasks, irrigation, pre-washing, etc.). These applications are wide-spanning and interest almost all countries.…”

Research on membranes and their associated processes was initiated in 1970 at the University of Paris XII/IUT de Créteil, which became in 2010 the University Paris-Est Créteil (UPEC). This research initially focused on the development and applications of pervaporation membranes, then concerned the metrology of ion-exchange membranes, then expanded to dialysis processes using these membranes, and recently opened to composite membranes and their applications in production or purification processes. Both experimental and fundamental aspects have been developed in parallel. This evolution has been reinforced by an opening to the French and European industries, and to the international scene, especially to the Krasnodar Membrane Institute (Kuban State University—Russia) and to the Department of Chemistry, (Qassim University—Saudi Arabia). Here, we first presented the history of this research activity, then developed the main research axes carried out at UPEC over the 2012–2022 period; then, we gave the main results obtained, and finally, showed the cross contribution of the developed collaborations. We avoided a chronological presentation of these activities and grouped them by theme: composite membranes and ion-exchange membranes. For composite membranes, we have detailed three applications: highly selective lithium-ion extraction, bleach production, and water and industrial effluent treatments. For ion-exchange membranes, we focused on their characterization methods, their use in Neutralization Dialysis for brackish water demineralization, and their fouling and antifouling processes. It appears that the research activities on membranes within UPEC are very dynamic and fruitful, and benefit from scientific exchanges with our Russian partners, which contributed to the development of strong membrane activity on water treatment within Qassim University. Finally, four main perspectives of this research activity were given: the design of autonomous and energy self-sufficient processes, refinement of characterization by Electrochemical Scanning Microscopy, functional membrane separators, and green membrane preparation and use.

“…The interactive effect of different variables on the production amylase by Enterobacter cloacae strain D1 was studied through response surface methodology based on the method previously described by Aloulou et al [23]. The half fraction type of central composite design (CCD) was employed to study the effect of five (5) numeric factors (pH, temperature, inoculum concentration, peptone concentration and yeast extract concentration) on a response variable (amylase activity) with each factor set to 5 levels: plus and minus alpha (axial points), plus and minus 1 (factorial points) and the centre point.…”

Background: Production of amylase by Enterobacter cloacae D1 was optimized in this study using central composite design (CCD) of response surface methodology (RSM). Methodology: Effects of five numeric factors (pH, temperature, inoculum concentration, peptone and yeast extract) on the production of amylase were examined. Amylase production was first screened using plate technique and amylase assay thereafter carried out using the dinitrosalicylic acid (DNSA) method. The CCD-RSM experimental set-up involved 30 runs with 5 levels of independent variables. Results: The amylase-producing bacterium Enterobacter cloacae strain D1 was identified based on the phylogenetic tree analysis of its sequence. The sequence has been submitted to GenBank under the accession number: MZ477010. The isolate had 98% similarity to the GenBank match Enterobacter cloacae strain ATCC 13182. Optimum conditions that yielded maximum amylase (34.43 U/mL) were pH 5; temperature 40 ℃; inoculum concentration 3%; peptone 1.2% and yeast extract 0.5%. Conclusion: This study has demonstrated efficient amylase production from Enterobacter cloacae strain D1 isolated from cassava effluent-impacted soil from Rumuosi, Port Harcourt, Rivers State. In addition, optimization of the critical factors of amylase production resulted in 3.4 fold increase in amylase activity. The enhancement of amylase production by the RSM techniques shows that amylase from this strain can be scaled-up for industrial application.

“…A Box-Behnken response surface approach [21][22][23] was used to identify factors affecting the membrane fouling and to optimize the overall permeate flux. Three independent factors were carefully studied: the crossflow velocity (0.5 to 1.5 m/s) [24]; transmembrane pressure (0.5 to 1.5 bar) [25]; and pulsatile time interval (60 to 120 s) at a constant pulse duration (0.8 s).…”

In this comprehensive study, a seven-channel ultrafiltration (UF) titania membrane was used to investigate the impact of the pulsatile cleaning process on the crossflow filtration system. Seventeen experimental runs were performed for different operating conditions with a transmembrane pressure (TMP) varying from 0.5 to 1.5 bar, a crossflow velocity (CFV) ranging from 0.5 to 1 m/s, and pulsatile parameters within an interval varying from 60 to 120 s with a duration of 0.8 s, and collecting membrane permeate flux and volume data. The optimized operating conditions revealed that a TMP of 1.5 bar, a CFV of 0.71 m/s, and a pulsatile cycle of 85 s were the best operating conditions to reach the highest steady permeability flux and volume of 302 LMH and 8.11 L, respectively. The UF ceramic membrane under the optimized inputs allowed for an oil-rejection ability of 99%. The Box–Behnken design (BBD) model was used to analyze the effect of crossflow operating conditions on the permeate flux and volume. The analysis of variance (ANOVA) indicated that the quadratic regression models were highly significant. At a 95% confidence interval, the optimum TMP significantly enhanced the flux and permeate volume simultaneously. The results also demonstrated a positive interaction between the TMP and the pulsatile process, enhancing the permeate flux with a slight impact on the permeate volume. At the same time, the interaction between the CFV and pulsatile flow improved the permeability and increased the permeate volume.
