  • WWTP Sludge reduction case study

    Introduction The City of Spring Valley, IL was seeking bioaugmentation to reduce the economic burden of sludge dredging and disposal and to evaluate the possibility of restoring the microbiological activity in the lagoon. The lagoon was flooded several times from the near-by Illinois River, which created different strata of inorganic silt/organic sludge and densely packed sludge at the ...

  • A perfect pair: SBR designs & advanced aeration technology

    Conventional sequencing batch reactors (SBRs) that utilize diffused-air networks have existed in the U.S. for about three decades now. The reliability of controls and instrumentation has significantly improved in the last 10 to 15 years, and as a result, SBR plant designs are becoming more widely accepted. The attractiveness of their compact layout and ease of operation has also helped increase ...

  • Maximizing Energy Recovery through Digester Gas Management System Enhancement

  • Wastewater lagoons – a new aeration concept

    The use of wastewater treatment lagoons, or stabilization ponds, is a common practice for rural municipalities and industrial facilities. Through the years there have been numerous designs for these ‘sludge settling basins,’ ranging from facultative, partial aerated, and fully aerated systems. But the primary reason for these systems is to utilize relatively shallow earthen ponds, or ...
