“…The ceramics with compositions of 2 and 3 would showcase similar properties. The 50O (4) composition has a very distinct structural character compared with these clusters [46,50]. This hypothesis will be reflected in the further microstructural investigation.…”

This article discusses the characterization of local clay-organic (CO) ceramics used in the microfiltration application in India. Local clay and sawdust were the raw materials for these ceramics. Wet mix with specified volume fractions of these raw materials was hydroplastically formed to square plates, cured, and fired at 850°C. Once fired, these ceramics showed a prominent presence of silica, alumina, and oxides of iron. Quartz, potassium feldspar, and hematite are the major minerals in these ceramics. The dominance of pores orthogonal to the surface was a feature in this family of ceramics. The 50O composition of the CO ceramics is observed to have a maximum frequency of orthogonal pores. Therefore, an example of gravity-based filtration flow models of this material shaped in distinct forms is carried out to enumerate possible scaling. The surface roughness of the cured specimen plate varies linearly with the porosity of the mixture. The compressive strength shows a polynomial increase with an increase in the values of surface roughness. The fracture toughness is a linear function of the surface roughness of these CO ceramics.

“…The properties of the six samples clearly lie disconnected from each other. Here, the properties of 1 (clay) and 4 (50O) can be said to be inversely correlated since they are located at quadrants which are diagonally opposite to each other [49,50]. The closeness of 4 (50O) to the origin of the score plot in Fig.…”

“…Ceramic water filters rely on small pore sizes of the ceramic's material to filter dirt, debris, and bacteria out of the water [16], making this technology ideal for use in developing countries [17]. The filter is made of a mixture of clay and sawdust kneaded together, molded, dried and fired to make it a structurally stable vessel [18]. The ceramic water filter can be coated with colloidal silver [15], or Biomass of Bacillus subtilis -a combination of Bacillus subtilis and Silver nitrate.…”

A Significant proportion of rural households lacked access to improved and safe drinking water due to chemical and microbial contamination. Point-of-use (POU) water filters made from cheap, locally available ceramic materials and additives can achieve quality water parameters. Ceramic water filters were prepared by combining clay minerals with additives. Sawdust was used as a burnout material to achieve porosity and enhance the filtration rate. Silver nitrate, charcoal, periwinkle shell, snail shell, and biomass of Bacillus Subtilis were added in different ratios. The filter was formulated with charcoal, sawdust, snail shell, and periwinkle shell to remove microbes and treat heavy metals through the adsorption process. The filters were molded and fired in a temperature range of (700oC - 900oC). Characterization of the clay mineral, physiochemical and Microbial tests were conducted on the ceramic and water. Antimicrobial test was carried out on the biomass of Bacillus subtilis. Mineralogical (XRD) and elemental analysis of the clay, snail, and periwinkle shells showed high percentage composition of serpentine (a clay crystal), plagioclase, a mixture of feldspar minerals albite (sodium aluminosilicate - NaAlSi3O8), anorthite calcium aluminosilicate- CaAl2Si2O8) and Calcium (70-97 %composition) respectively. The results showed a greater proportion of silica in the clay, suggesting the material is silicate. Filtration rate was estimated at 1.125 L/hr. The result showed the filter has 96.72%, 99.26%, and 66.67% colony removal efficiency for heterotrophic bacteria, coliform, and fungi respectively. The filter showed about 70% - 96% efficiency for the treatment of physiochemical parameters in wastewater.
