The equipment used in wastewater treatment plants supports various processes to ensure efficient and effective treatment of wastewater. This equipment is critical in each stage of physical, chemical and biological treatment methods. Commonly used equipment includes screens, grit traps, sedimentation tanks, biological reactors, filtration systems and disinfection units.
Screens ensure that large solids in wastewater are retained, enabling subsequent treatment stages to occur efficiently. Grit traps, on the other hand, ensure that fine solids in water are sedimented and separated. Sedimentation tanks are an important treatment stage where suspended solids in water are sedimented and separated.
Biological reactors ensure that organic substances in wastewater are broken down by microorganisms and removed.
