Sewage Treatment Plant - Filter Feed Pumps Types and Operation And Maintenance Considerations

Introduction: Filter Feed Pumps are essential components in industrial water treatment systems, facilitating the movement of water through filtration stages to enhance its quality. These pumps draw clarified water and direct it through the Pressure Sand Filter (PSF) and Activated Carbon Filter (ACF), which work together to remove solid impurities, organic matter, and undesirable odors. By ensuring consistent water flow and pressure, Filter Feed Pumps play a crucial role in maintaining efficient filtration processes. FILTER FEED PUMPS Filter Feed Pumps are used to draw water from the clarified water sump and pass it through the Pressure Sand Filter (PSF) and Activated Carbon Filter (ACF), which are installed in series to improve water quality. PRESSURE SAND FILTER (PSF) Working Principle: The upper layers of sand perform the actual filtration function, while gravel layers provide physical support. Specialized sand with a specific particle size is used to trap solid impurities present in...

Sewage Treatment Plant - CLARIFIER/ SETTLING TANK Basics

Introduction: The Clarifier, or Settling Tank, is a crucial component in the sewage treatment process, designed to separate solid sludge from treated water through sedimentation. It ensures that bacterial flocs settle efficiently while preventing turbulence, allowing for the collection of sludge and the discharge of clarified water. Proper operation of the clarifier is essential to maintaining a balanced biological process in the treatment plant, preventing microorganism loss, and ensuring smooth wastewater processing. CLARIFIER/ SETTLING TANK 1 The sewage inlet pipe brings sewage from the aeration tank. 2 The center-feed well takes this incoming sewage and gently releases it in the settling tank, without causing any disturbance or turbulence. 3 The sludge is only slightly heavier than water; so it takes time to sink. It slides down the steeply sloped walls of the tank toward the center of the bottom. 4 The bacterial flocs7 collect here in high concentration. 5 The sludge delivery pipe...
