  • Are oil & grease emissions regulated in sewage treatment plants?
  • To protect the normal functioning of sewage treatment plants, emissions of oil and grease to the local wastewater drainage system are also subject to regulation.
  • How does oil and grease affect biological wastewater treatment processes?
  • Furthermore, oil and grease affect the aerobic biological wastewater treatment processes by reducing the oxygen transfer rates. Similarly, oil and grease reduce the efficacy of anaerobic treatment processes by reducing the transport of the soluble substrates to the bacterial biomass (Rinzema et al. 1994).
