“…The utilization of porous ceramic membranes using low-cost materials has attracted much interest. Organic ceramic membrane technology has many disadvantages such as poor stability, poor acid and alkali corrosion resistance and non-renewable while Inorganic membrane has been studied and used by researchers due to its high-temperature resistance, high permeate flux, chemical corrosion resistance and good mechanical strength [13]. Many materials have been reported in the literature for the manufacture of ceramic membranes such as alumina (Al 2 O 3 ) [14], zirconia (ZrO 2 ) [15], titania (TiO 2 ) [16], silicon carbide (SiC) [17], glass (SiO 2 ) [18], or a combination of these metal oxides, and composites or combinations of oxides and non-oxides [19], as well as clay minerals (e.g., kaolin [20], mullite [21], dolomite [22], etc.).…”

“…Figures 10-13 show the % reductions in COD with time for various oil concentration (100, 150, and 200 ppm) for Bentonite (B), Bentonite with melamine (B+M), Clay (C) and Clay with melamine (C+M) respectively. From the above-mentioned figures, it is clear that the % reduction in COD increases with increasing time and also the % reduction in COD increases with increasing concentration.…”

Four distinctive Ceramic membranes have been synthesized using bentonite and Egyptian clay with the expansion of melamine. The addition of melamine (~ 1% by wt.) enhanced the porosity, density, the thermal stability and water permeability of the membranes made from bentonite or Egyptian clay while decreasing the chemical stability of either bentonite or Egyptian clay membranes. The most noteworthy level of decrease in COD (94.7%) is acquired for the concentration of 200ppm with saturating flux of 4.63 E-05 (m 3 /m 2 .s) utilizing (B+M) membrane. The cost of the four manufactured clay membranes was assessed based on raw materials used in the present investigation.

A large amount of oil-containing wastewater is generated in the oil industry. Before injection into the layer, oil and mechanical impurities must be removed from the oil-containing wastewater to the specified limits for injection into the oil formation. During the purification of oil-containing waste water, the method of settling on structures of various designs is widely used. To intensify the sedimentation processes of oil-containing wastewater, pre-treatment methods are used before sedimentation in treatment plants. One of the most effective is the process of coalescence on structures with the use of granular coalescing nozzles. Granulated coalescing materials based on polymer materials and expanded clay have been developed to intensify the process of oil-containing wastewater purification. Based on the experiments, it was found that the best materials for coalescence purposes are coarse-grained coalescing hydrophobic loads for wastewater filtration at high speeds, which operate in self-regeneration mode. This increases the depth of oil-containing wastewater purification and reduces the duration of the settling process by two or more times.

In the present study, a high-efficiency petroleum hydrocarbon-degrading bacterium MX1 was screened from petrochemical wastewater sludge, and MX1 was identified using morphological, physiological, and biochemical experiments and combined with 16S rDNA. Results showed that the the MX1 strain belongs to Enterobacter sp. The degradation conditions were an incubation time of 18 days, temperature of 30 °C, pH of 7, and salinity of 2% (w/v), and the degradation proportion was 37.41% for 7 days. The combination of microwave and ultraviolet mutagenesis yielded the strain MXM3U2. The mutant strain had a petroleum hydrocarbon breakdown efficiency of 56.74% after 7 days of culture, and this value was 51.66% higher than the original strain. The number of strains and the rate of degradation of n-alkanes (C16, C24, C32, and C40) decreased steadily with the increase in carbon chains in the degradation test. GC/MS (Gas chromatography mass spectrometry) results showed that in the process of degrading crude oil, the hydrocarbons with carbon number C < 24 were degraded first, followed by hydrocarbons with carbon number C > 24. The strains had a good degradation effect on pristane, naphthalene, and phenanthrene. In this study, a high-efficiency petroleum hydrocarbon-degrading bacterium was screened via microwave-ultraviolet composite mutagenesis technology.
