The design and assessment of environmentally friendly ceramic manufacturing processes employing sludge from processed industrial wastewater

Sludge is a substantial consequence of the reuse and recycling of wastewater using innovative technology, and while it must be disposed of, using sludge as a resource in the building sector is one of the most economically viable solutions. Given the enormous amount of this sort of trash produced by industrial sites throughout the world and the tendency toward fewer leftovers, several research have examined ways to valorize this product to reduce environmental degradation and ensure a sustainable approach to the environment. The goal of this study is to maximize the usefulness of the wastewater treatment sludges used in the production of ceramic items by optimizing the values of the key process parameters using practical experience. In this work, we used a real-world case study for a Moroccan industrial site that disposes of a lot of sludge to examine the chemical makeup and evolution of sludge over the course of a year. The purpose of this study is to analyze the industrial sludge from the evaporation basins of the solar power plant, with a focus on recycling for the manufacture of red ceramic bricks. Mixtures were created to assess the viability of turning these sludges into ceramics. by blending the muck with the indigenous potters' preferred sea clay. S1 (100% sludge), S2 (100% clay), S3 (50% sludge and 50% clay), S4 (25% clay and 75% sludge), and S5 (25% sludge and 75% clay) were the five mixes that were tested. To determine the granulometric, mineralogical, and chemical composition of mixtures, analysis has been done. According to the findings, the mixture S3 (which contains 50% mud and 50% clay) with a mechanical resistance of 27 MPa. has the best plasticity for making ceramics.
