Hybrid Baffled Flocculator in Benha Water Treatment

A hybrid baffled flocculator (HBF) is employed in this study in an effort to lower the footprint area and enhance the quality of drinking water. The process known as hydraulic mixing with media is less expensive than expanding a water treatment facility. To evaluate this technology, we use a pilot plant equipped with baffles loaded with packing material. Plastic, foam, and gravel have all been tested as turbidity-removing media. The experimental facility was designed to be similar to a traditional water treatment plant located in Benha City, Egypt. Hydraulic mixing is used in place of rapid flash mixing and gentle mechanical mixing. To assess the removal and hydraulic efficiency, this study compares the hydraulic model with and without media. Many effective parameters have been studied like media type, alum dose, and detention time. Results show that the hydraulic efficiency of the reg test is increased by packing material. Gravel has the highest average of 50% elimination efficiency for T = 18 min and alum dose = 26 P.P.m. Plastic has the second-highest turbidity removal efficiency, with an average of 45%. Finally, employing foam reduces turbidity in the Nile River by an average of 33%. Conversely, the average percentage removal while employing vertical baffles alone without media is 28%, the percentage of turbidity that was removed at varying alum doses varies from 14 to 33%, and the highest percentage of removal is achieved with a 30 P.P.m alum dosage. In addition, the average percent removal of foam, plastic, and media is 30%, 36%, and 43%, respectively.
