Annually, a city with 500,000 inhabitants generates approximately 115.5 million cubic meters of wastewater. The treatment of this wastewater is efficiently managed using activated sludge, which comprises a diverse community of protozoa, infusoria, lower crustaceans, algae, and microorganisms. These organisms facilitate the effective treatment of large volumes of wastewater in treatment plants. However, the activated sludge proliferates by consuming organic materials in the wastewater, resulting in the accumulation...
