  1. III. Water TreatmentTopicIII.4. Upflow Sludge Blanket Clarifiers: Processes and Facilities Processes: I. Particularities • Applying of contact coagulation • Flocullation chamber don’t needed II. Advantages • Higher rate of coagulation • Deeper process of coagulation • Less coagulant quantity needed • Negligible temperature impact III. Disadvantages • More sludge production • Not applicable for SS > 2500 mg/l

  2. Upflow Sludge Blanket Clarifying Processes Basic Parameters Suspended solids Upflow velocity Distribution coefficient mg/l mm/s - < 50 1,5 - 1,6 0,95 50 - 100 1,6 - 1,8 0,90 100 -500 1,8 - 2,0 0,85 500 - 1000 2,0 - 2,2 0,75 1000 - 2000 2,2 - 2,5 0,70

  3. Corridor Type 1 - perforated coarse water distribution pipes 2 - sludge blanket 3 - sludge overflow orifices 4 - sludge thickening zone 5 - water clarifying zone 6 - channels for clarified water 7 - collector for clarified water 8 - sludge withdrawing pipes Upflow Sludge Blanket Clarifiers

  4. Circular Type 1 - inflow channel; 2 - air release chamber; 3 - inlet water pipes; 4 - perforated water distribution pipes; 5 - protecting shields; 6 - sludge blanket; 7 - lamellas; 8 - water clarifying zone; 9 - perforated outlet pipes for clarified water; 10 - collecting channel Upflow Sludge Blanket Clarifiers
