“…Which indicated that PFcs was of the highest porosity and BF + AC was the least. The result of the porosity were in line with other studies [ 35 , 36 ]. The variations in the apparent porosity of the CWFs could be attributed to the quantity of burnout material added to the clay during production of the filter, that is the variations in porosity is directly proportional to the quantity of combustible matter added [ 36 , 37 ].…”

“…It is then necessary to proceed with its elimination and, failing that, its reduction to limit values before discharging any effluent containing it into the environment [12] [13]. Several methods of eliminating these metals are used, including precipitation, adsorption, ion exchange and membrane filtration [14] [15] [16] [17].…”

Copper is considered a heavy metal that can be toxic at certain concentrations and its presence in water is a potential threat to public health. These heavy metals also contribute to a remarkable degradation of the environment, hence the need for effective treatment methods to remove them. In this study, a mixture of titaniferous sand and calcium silicate was used as adsorbent material to eliminate copper in solution. The calcium silicate was synthesised from fluosilicic acid, which is a by-product of phosphoric acid manufacture. The titaniferous sand is a residue from a mining industry. Both adsorbents were characterised by infrared spectroscopy and X-ray fluorescence to determine their compositions and physicochemical properties. The response surfaces, through the Box-Behnken model, were used to model and optimise various adsorption parameters, namely initial copper concentration (A: 60 -200 mg/L), adsorbent dose (B: 0.1 -0.6 g) and pH (C: 4 -10). The copper removal efficiency (98.92%), after statistical analysis, was obtained under the following optimal conditions: an adsorbent dose of 0.55 g, an initial copper concentration of 197.25 mg/L and a pH of 9.85. The study of the effects of the operating parameters showed that they had a positive effect on the copper removal efficiency.

The paper presents the results of a study of the filtering capacity of some filters from ceramic composite materials made on laboratory installation. The filtration process involved applying a pressure gradient to the filter by means of a centrifugal pump from the filter installation. The ceramic composite materials used to make the filters have a bentonite-based matrix. To achieve the porous structure, the matrix was reinforced with SiC and Al2O3 ceramic powders and to control the pore size, additional Al metal particles were added. The stages of obtaining and characterizing the filters, respectively of testing their filtering capacity of the suspended particles from the rainwater are presented distinctly. In conclusion, the dependencies between a series of structural and geometric characteristics of the filtering capacity were established.
