“…Where: Vi, Vp, and Vr are the initial, permeate, and retentate volumes, respectively; In concentration mode (without recirculation of the permeate), the mass balance is determined using the following classical equation: (10) where: V i , V p , and V r are the initial, permeate, and retentate volumes, respectively; and C i , C p , and C r are the initial oil concentration, oil concentration in the permeate, and oil concentration in the retentate, respectively On the other hand, the volume balance is given by Equation ( 11):…”

This work aims to determine the optimized ultrafiltration conditions for industrial wastewater treatment loaded with oil and heavy metals generated from an electroplating industry for water reuse in the industrial process. A ceramic multitubular membrane was used for the almost total retention of oil and turbidity, and the high removal of heavy metals such as Pb, Zn, and Cu (>95%) was also applied. The interactive effects of the initial oil concentration (19–117 g/L), feed temperature (20–60 °C), and applied transmembrane pressure (2–5 bar) on the chemical oxygen demand removal (RCOD) and permeate flux (Jw) were investigated. A Box–Behnken experimental design (BBD) for response surface methodology (RSM) was used for the statistical analysis, modelling, and optimization of operating conditions. The analysis of variance (ANOVA) results showed that the COD removal and permeate flux were significant since they showed good correlation coefficients of 0.985 and 0.901, respectively. Mathematical modelling revealed that the best conditions were an initial oil concentration of 117 g/L and a feed temperature of 60 °C, under a transmembrane pressure of 3.5 bar. In addition, the effect of the concentration under the optimized conditions was studied. It was found that the maximum volume concentrating factor (VCF) value was equal to five and that the pollutant retention was independent of the VCF. The fouling mechanism was estimated by applying Hermia’s model. The results indicated that the membrane fouling given by the decline in the permeate flux over time could be described by the cake filtration model. Finally, the efficiency of the membrane regeneration was proved by determining the water permeability after the chemical cleaning process.

“…Treatment of oily wastewater from wastewater is very difficult. In the Agarwal et al (2020) study, especially for the treatment of oily wastewater, thick and FA were used in the production of ceramic membranes [4]. Another example given on the use of ceramic membranes obtained from FA for the separation of oily wastewater with the microfiltration process is the study of Zou et al (2019) [50].…”

The need for water is increasing owing to the rapidly increasing world population, urbanization, industrialization, global climate changes, and intensive agricultural activities. While the importance of water is increasing day by day, the purification and reuse of water have become more and more essential. Reducing the pollutants at the source as much as possible and if it will be given to the receiving environment, giving the wastewater treatment in accordance with the current discharge regulations, are priority processes. Of the advanced separation methods, membrane separation technology is used to reduce water resource use and control environmental pollution and has advantages such as high separation efficiency, convenient operation, compact equipment, and energy-saving. Membranes are divided into two categories according to their structures: organic and inorganic membranes (or ceramic membranes). Compared to organic membranes, inorganic membranes have many advantages such as high thermal and chemical stability, good resistance to microbial erosion, easy regeneration and cleaning, high mechanical strength, and long-term stability in harsh conditions. The high cost of ceramic membranes is an important disadvantage. In recent years, it is seen that membrane production costs are reduced by using natural minerals such as kaolin, quartz, bauxite, diatomite, clay, limestone, dolomite, zeolite, and industrial wastes instead of the commonly used ceramic membrane raw materials. By using these raw materials, besides reducing the cost of ceramic membranes, it also contributes to lowering the temperatures required for their production. In this study, studies on ceramic membranes produced from industrial wastes (waste ash, sawdust, sewage sludge, construction and demolition wastes, waste diatomite, rice husk ash, sugarcane pulp ash, corn cob ash waste etc.) were examined.

“…To overcome this limitation, scientific research has been focused on producing ceramic membranes using low-cost alternative starting materials [ 20 , 21 ]. Previous studies have reported the utilization of various abundant and inexpensive solid waste materials and geomaterials in the preparation of ceramic membranes such as kaolin [ 22 ], phosphates [ 23 ], natural perlite [ 21 ], natural magnesite [ 24 ], bentonite [ 25 ], pozzolan [ 26 ], fly ashes [ 27 ], etc. The use of industrial solid wastes as raw precursors in the manufacture of ceramic membranes helps decrease solid waste, produce low-cost materials of high value, and protect the environment.…”
