  1. activated sludge microbes and converted to biomass, water, carbon dioxide, and other gases • Nitrification – The process through which ammonia is oxidized to nitrite and nitrate • Denitrification – A process by which nitrates and nitrites are converted to gaseous end products, primarily nitrogen gas.
  2. About Sewage, sludge; 1 cubic meter of Sewage, sludge weighs kilograms [kg] 1 cubic foot of Sewage, sludge weighs pounds [lbs] Sewage, sludge weighs gram per cubic centimeter or kilogram per cubic meter, i.e. density of sewage, sludge is equal to kg/m³.In Imperial or US customary measurement system, the density is equal to 45 pound per cubic foot [lb/ft³], or
  3. The water in between the sludge and scum is pretty clear water. This is the water that is eventually absorbed into the soil. Blockages most often occur with the buildup of sludge over time. These blockages can lead to overflow, which is potentially dangerous for everyone. It can clog the soil absorption area, causing septic systems to fail.
  4. feet) in diameter and meters (3 to 8 feet) deep with rock size varying from cm (1 to 4 inches). Most rock media provide approximately m2/m3 (15 sq ft/cu ft) of surface area and less than 40 percent void space. Packed plastic filters (bio-towers), on the other hand, are smaller in diameter (6 to 12 meters (20 to 40 feet.
  5. sludge removal. Hopper bottoms shall have a maximum dimension of two (2) feet. Extra-depth sludge hoppers for sludge thickening are not acceptable. Protective and Service Facilities Operator Protection All clarifiers shall be equipped to enhance safety for operators. Such features shall.
  6. Thickening of sludge at the Patapsco plant is accomplished by gravitation. Solids from primary and secondary treatment are pumped into the two 65 feet diameter sludge-thickening tanks. These two fiberglass domed tanks take primary sludge (1% solids) and thicken it to 6% solids and secondary sludge (% solids) to % solids.
  7. A sludge digester equipped with a floating cover is 31 ft. inside diameter. The corbels lead pump comes on when the wet well is at 5 feet and turns off at feet. When two pumps are required, the lag pump comes on at 7 feet and continues to run with the lead .
  8. Primary sludge is produced if primary clarifiers precede the oxidation ditch. Sludge production for the oxidation ditch process ranges from to kg TSS per kg ( to lb. TSS per lb). BOD applied (Sherwood Logan and Associates, ). Typical sludge production is kg TSS per kg of BOD ( lb TSS per lb. of BOD). This is less than.
  9. Velocities must be kept above 2 feet per second. Grease content can cause serious clogging, and grit will adversely affect flow characteristics as well. Adequate clean-outs and long sweep turns will be used when designing facilities of these types. PIPING. Sludge withdrawal piping .
