Web23 Apr 2024 · For general urban sewage, the reflow sludge concentration in the secondary sedimentation tank is usually 4-8kg/m3. If the maximum value is 8kg/m3, MLSS in the aeration tank with a reflux ratio of 150% is 4.8kg /m3, and the maximum MLSS in the actual design is generally not more than 4.5kg/m3. Web14 Jan 2015 · First steps to solving floating sludge is to look for what is causing the problem. In the interim period, I would immediately check clarifier bed depth and increase recycle if bed depth is too high. You may also want to put water spray on the clarifier to "knock" down the floating sludge.
Web10 Apr 2024 · Activated sludge process: The essential features of the activated sludge process are an aeration stage, solids-liquid separation following aeration, and a sludge recycle system. Wastewater after primary treatment enters an aeration tank where the organic matter is brought into intimate contact with the sludge from the secondary clarifier. WebThe residue that accumulates in sewage treatment plants is called sludge (or biosolids).
