CWEA Mainstream AMX Presentation

Dr. Sandeep Sathyamoorthy, PhD, PE, Black and Veatch presenting at 2018 CWEA Side- Stream & Mainstream Nutrient Workshop. He presented his findings on BKT's anammox. Click on the Button below for the presentation material.


Mainstream Anammox Process for Nutrient Removal and Recovery

  • Municipal Tertiary Treatment
  • 2-stage Partial Nitritation + Anammox (PN+A) Upflow Biofiltration System
  1. Low Temperature
  2. High C/N ratio
  • Stable operation via separate enrichment of AOB & AMX

Technical Information

AGR+AMX Process

AMX main1.png
  • Stable nitritation and AOB granule generation in the sidestream
  • Achieved nitritation by supplying AOB from sidestream to the mainstream
  • BBF-AMX :
    • Maintain high concentration anammox microorganisms on pores and surfaces of EPP media
    • Physical filtration ensures treatment quality (<2 NTU)
    • Separate solid-liquid separation (sedimentation, filtration) is unnecessary
 

LED Nitritation Process

  • Combination of blue LED and reactor operating conditions for effective NOB suppression
  • Simultaneously achieve organic removal and nitritation
  • BBF-AMX:
    • Maintain high concentration anammox microorganisms on pores and surfaces of EPP media
    • Physical filtration ensures treatment quality (<2 NTU)
    • Separate solid-liquid separation (sedimentation, filtration) is unnecessary
 

Photo-Granule Nitritation Process

  • Simultaneous organic removal and nitritation using algae granule
  • Easily separate solid-liquid by granule formation composed of algae, heterotrophs, and AOB
  • Utilizes air generated from photosynthesis and does not require a separate air supply
  • BBF-AMX :
    • Maintain high concentration anammox microorganisms on pores and surfaces of EPP media
    • Physical filtration ensures treatment quality (<2 NTU)
    • Separate solid-liquid separation (sedimentation, filtration) is unnecessary
