Nitrifying granules effectively removed ammonia from diverse wastewaters, including industrial and domestic sources. These granules demonstrate broad applicability in wastewater treatment plants for efficient nitrification.

Area of Science:

  • Environmental Engineering
  • Microbiology
  • Biotechnology

Background:

  • Nitrification is a critical step in wastewater treatment for ammonia removal.
  • Aerobic upflow fluidised bed (AUFB) reactors are used for producing nitrifying granules.
  • The performance of these granules in various wastewater types requires further investigation.

Purpose of the Study:

  • To evaluate the performance of nitrifying granules in different ammonia-containing wastewaters.
  • To assess the efficiency and applicability of nitrifying granules in wastewater treatment.

Main Methods:

  • Nitrifying granules were produced in an aerobic upflow fluidised bed (AUFB) reactor.
  • Performance was tested in synthetic, inorganic, industrial, and domestic wastewaters.

  • Ammonia removal rate and efficiency were measured under varying conditions.

    • Main Results:

    • High ammonia removal rate (16.7 kg-N/m3/day) and efficiency (>80%) were achieved in synthetic wastewater with pure oxygen.
    • Granules maintained high density and stability in a continuous stirring tank reactor (CSTR) for low-concentration inorganic wastewater.
    • Effective nitrification was observed in high-salinity industrial wastewater and in combination with activated sludge for domestic wastewater.

    Conclusions:

    • Nitrifying granules show wide applicability for nitrification across various wastewater types.
    • The granules offer a robust and efficient solution for ammonia removal in wastewater treatment plants.
    • Their performance is sustained even under challenging conditions like high salinity or mixed with activated sludge.
