In the realm of wastewater treatment, solids contact clarifiers stand as a significant innovation, enhancing the process of water purification by consolidating several steps into a single unit. They operate by recycling settled sludge and mixing it with incoming wastewater in a contact zone, which promotes the aggregation of particles. This process aids in the […]
Safe drinking water and effective wastewater treatment are critical for protecting public health and the environment. Chemical technologies play an important role alongside physical and biological treatment methods. This article provides an overview of key chemical processes used, design considerations, and challenges for further improvement. Chemically-enhanced sedimentation (coagulation and flocculation) is used to remove suspended […]
