Production of Bricks Using Spent Diatomaceous Earth Used in Brewing Industry
In breweries, diatomaceous earth (DE) is used as a filter material. Spent diatomaceous earth (SDE), as an industrial waste, is mainly generated once this DE pores are filled with impurities generated from brewing industries. After the final filtering process, this spent DE is disposed into dumping areas leads to environmental pollution. Therefore, as a remedy for that problem, SDE can be adulterate with clay to produce bricks. Mixing clay with SDE leads to an increase in the quality of the bricks. Also, the incorporation of SDE for brick production can reduce the adverse effects on the environment by reducing the quantity of clay excavated and discharged SDE. This study was conducted to analyze the suitability of using SDE as a secondary raw material for brick production. The chemical characteristics of SDE were analyzed using both XRF and TGA tests. Bricks containing 0, 5, 10, and 15 wt% of SDE were sun-dried and fired at 950 ℃ for 6 h with suitable temperature ramp. The obtained results reveal that compressive and bending strengths were increased with increasing the SDE weight percentage. Highest compressive strength (4.78 MPa) and bending strength (0.57 MPa) were recorded for the sample prepared with 15 wt% of SDE. Furthermore, the addition of SDE is worth as no significant differences in physical properties are observed. To produce SDE incorporated bricks on a large scale, further research and development by considering, the technical, economic, and environmental aspects of SDE are recommended.
