Afterward, the wastewater flows into sedimentation ponds, which come in various types, such as vertical flow and horizontal flow. Inside the sedimentation ponds, gravity causes the larger flocs formed by coagulation to settle at the bottom, while the clarified liquid exits from the top of the pond, thereby achieving solid-liquid separation. This equipment effectively removes suspended solids, some heavy metals, and organic matter from water, playing a crucial role in numerous fields like industrial wastewater treatment and municipal wastewater treatment. It improves water quality and reduces the pressure on subsequent treatment stages.
