Activated Sludge Microscopy

One of Aqua Enviro’s techniques for the initial assessment of the activated sludge process is microscopic examination. This test involves the visual assessment of biomass floc structure/size/shape, protozoa, metazoa and filamentous bacteria.

Findings from the visual assessment our used to indicate the overall health of the plant, changes that may have occurred in the influent, process conditions (F/M, sludge age) and any problems that maybe occurring within the ASP (low dissolved oxygen, under/overloading, nutrient deficiency, toxicity)

Microscopy report will be produced which will assess:-

  • Overall health of the Mixed liquor
  • 30min settlement rate
  • Floc integrity, size, shape and structure
  • Filamentous bacteria species and abundance
  • Protozoa and metazoa species and abundance
  • Brief summary of observations and process conditions
  • Potential treatment solutions for any areas of concern

1kg or 1L of test material is required for the testing.
