The activated sludge system is one of the most widely used and efficient effluent treatment processes in the world. The main objective is to balance different microorganisms, which form the biological floc, which in turn, when entering a zone without aeration, tend to settle, thus removing organic impurities from the effluent.

When an imbalance occurs in this environment, it is very common for operational problems to occur, such as:

• Low quality of biological flocs
• Excessive growth or absence of filamentous bacteria
• Presence of foam on the reactor surface
• Uncontrolled pH
• Final effluent is cloudy and/or contains sludge
• Low efficiency in COD/BOD removal
• Low dissolved oxygen index

Genetica Bioscience offers complete aerobic microscopic analysis, which analyzes several important parameters of the activated sludge system. Learn a little about this analysis:

Analyzed items

• Operational parameters of the unit

• Filaments containing sulfur granules
• Identification and quantification of microfauna
• Tetrads
• Clusters of nitrifying bacteria
• Algae
• Zoogloea sp.
• Foams
• Exopolymers
• Complete final diagnosis, with suggestions for improvements

With the technical report in hand, you will understand the interaction between the different bioindicator microorganisms present in the system and how this relationship can affect the efficiency of the treatment.

See how simple, easy and interactive it is (all reports come with a complete diagnosis):

Microphotograph (100x magnification). Biological flocs with medium size, rounded shape, firm resistance and compact structure.

Microphotographs (1000x magnification). Predominant presence of two types of filamentous bacteria. Suggests Thiothrix I and N. limicola II.

Microfauna specimen count

Microphotographs (400x magnification). Presence of micrometazoans from the rotifer group.

Microphotography (400x magnification). Zoogloea sp. When in excess it can cause viscous bulking.

Microphotograph. (Magnification 100x). Viscous floc due to excessive production of extracellular polymeric substances, which can result in poor sedimentation quality sludge in the secondary clarifier.
