Abstract:

This study aimed to determine the most efficient method to treat and reuse wastewater from the Ceramica Cleopatra factory in the 10th of Ramadan City, Egypt. A lab-scale pilot was designed and tested through four experimental runs. The system included three parallel treatment lines: the first combined chemical sedimentation with filtration, the second paired flotation with filtration, and the third consisted of cyclone separation followed by filtration. The wastewater used in the experiments had an initial concentration of 20,800 ppm. In the absence of coagulants, the sedimentation line achieved a removal efficiency of 99.51% (102 ppm effluent), the cyclone line reached 99.83% (34 ppm), and the flotation line recorded 99.70% (63 ppm). However, these results were inadequate for reuse in the ceramic industry. When ferric chloride was introduced as a coagulant, the sedimentation line’s efficiency increased to 99.95% (10 ppm), the cyclone line to 99.93% (16 ppm), and the flotation line to 99.94% (14 ppm). Despite the improvement, these results were still insufficient for industry requirements. The addition of coal filters significantly enhanced performance. The sedimentation line reached 99.95% efficiency (10 ppm effluent), the cyclone line achieved 99.97% (5 ppm), and the flotation line attained 99.96% (7 ppm). The cyclone line, combined with the coal filter, produced results that met the ceramic industry’s standards, marking it as the most optimal and effective wastewater treatment method for this application.
