TI  - Performance of 14 full-scale sewage treatment plants: comparison between four 
      aerobic technologies regarding effluent quality, sludge production and energy 
      consumption.
PG  - 2267-75
AB  - The performance of 14 Full-Scale Sewage Treatment Plants (STPs) was evaluated. 
      STPs were divided into four aerobic technologies: a) Aerated Lagoon (AL), and 
      three configurations of activated sludge technologies, b) conventional (CAS), c) 
      Extended Aeration (EA), d) Sequencing Batch Reactor (SBR). Comparison between 
      these configurations were made regarding: a) control parameters, organic loading 
      rate (OLR), Mixed Liquor Volatile Suspended Solids (MLVSS) concentrations, Food 
      to Microorganism ratio (F/M), sludge age (theta(c)), Hydraulic Retention Time 
      (HRT) and return sludge ratio (R); b) effluent quality, through 5-day Biological 
      Oxygen Demand (BOD5), Chemical Oxygen Demand (COD), Total Suspended Solids (TSS), 
      Total Kjeldahl Nitrogen (TKN), Total Phosphorus (TP); and c) indicators related 
      to sludge production (on a dry basis) and electrical energy consumption. Also, 
      complementary costs analyses were made. The results show that in terms of 
      effluent quality, for all configurations organic matter (BOD5 and COD) and TKN 
      removal efficiency were up to 90%, while TSS and TP were up to 90% and 50%, 
      respectively. However, CAS, EA, SBR, and AL had stability problems with effluent 
      concentrations. The results of the electrical energy consumption and sludge 
      production analyses show that SBRs reduce these indicators by 40%. Cost analysis 
      showed that CAS, EA, SBR and AL had similar cost structures, with more than 50% 
      of total operating and maintenance cost being related to electrical energy and 
      sludge management. Therefore, SBR could be defined as the configuration with a 
      more stable performance.
