A diverse range of volatile organic compounds (VOCs) are emitted from wastewater biosolids processing. Odorous emissions are predominately made up of volatile sulfur compounds (VSCs) which are typically the only odorants measured. However, a range of VOCs are known to contribute to malodours yet previous studies often overlook the contribution of VOCs in comparison with VSCs.

Odor emissions from biosolids limit opportunities for their beneficial reuse by land application. Odorous emissions are affected by the operation of stabilization processes via methods such as anaerobic digestion, aerobic digestion, alkaline treatment, thermal drying, or composting.

The composition of wastewater in sewer catchments is known to affect the performance of wastewater treatment plants (WWTPs). However, there is limited knowledge as to how catchment characteristics, such as types of catchment industries, impact odour emissions from downstream sludge processing and biosolids management.

The Urban Heat Island (UHI) effect can result in higher urban densities being significantly hotter (frequently more than 4 °C, even up to 10 °C) compared to their peri-urban surroundings. Such artificial heat stress increases the health risk of spending time outdoors and boosts the need for energy consumption, particularly for cooling during summer.

Cities are frequently experiencing artificial heat stress, known as the Urban Heat Island (UHI) effect. The UHI effect is commonly present in cities due to increased urbanization, where anthropogenic heat and human modifications have altered the characteristics of surfaces and atmosphere.

Highlights

  • Microbial LRV validation of AGS was conducted during start-up and mature operation.
  • LRV was assessed for four indicators and compared to Conventional Activated Sludge.
  • Start-up of AGS did not reduce microbial indicator LRV performance.
  • AGS is able to meet or exceed CAS health-based targets for pathogen removal.
  • Effluent quality from AGS is unlikely to impact downstream disinfection processes.

Highlights
 

  • Two feeding strategies were compared for aerobic granular sludgeSBR operation.
  • Performance of split anaerobic-aerobic and dedicated anaerobic feeding was compared.
  • Start-up, performance and microbial ecology were similar under both feed strategies.
  • Aerobic granular sludge ecology was different to conventional activated sludge.
  • Split anaerobic-aerobic feeding is a viable, cost-effective SBR retrofit solution.
