What Is Primary Sedimentation Tank? - Ceramics

What is primary sedimentation tank in sewage treatment plant? The Primary Settlement or sedimentation tanks are designed to reduce the velocity of the wastewater flow, allowing heavier organic solids (called raw sludge) to settle. They are the first stage of treatment after the removal of rags and grit in the inlet works. What is secondary []

2021-11-16  What is the function of primary sedimentation tank? A sedimentation tank allows suspended particles to settle out of water or wastewater as it flows slowly through the tank, thereby providing some degree of purification. A layer of accumulated solids, called sludge, forms at the bottom of the tank and is periodically removed.
