Filamentous Identification

"the Easy Way"

New training program

 

Higher life forms or "indicator organisms" as they are usually called are present in a biological system.  They indicate the health and age of the system. 

Amoeba- These are the first types of higher life forms that show up

More on Amoeba

 

This Flagellate is a Euglena taken at phase contrast at 200x

Flagellates are single celled organisms with a whip like flagella. They can be plant or animal like. They feed on soluble organic matter and can indicate high BOD levels, high F/M ratios or low MCRT. They are also found in young sludge or plants recovering from a recent upset condition.

More on Flagellates

Free Swimming Ciliates

These free swimming ciliates work on eating free swimming single celled bacteria and help to lessen the TSS in the water.  They are found during any sludge age but are dominant during high F/M or young sludge.

Crawling Ciliates

This is at 100x Phase Contrast of an Aspidicus crawling around a weak, open floc structure with filaments that have attached growth.

Stalked Ciliates

This photo of branched stalked ciliates is taken at 200x Bright Field

Stalked ciliates are found during most sludge ages but usually are dominant during middle aged sludge. They are typically indicators of good healthy, quality sludge age.

Suctoria

This picture is phase contrast at 400x

The picture of the suctoria is shown capturing a flagellate on the left side.

To the right of the suctoria is a zoogleal floc structure.

Suctorians are excellent indicators of good sludge.

 

Rotifers

The picture on the right is a rotifer. This picture was taken with Bright Field at 200x

Rotifers are multiple celled organisms that feed on good, stabilized floc. They are highly sensitive to high BOD loadings and toxic shocks. They are typically found in conditions with low F/.M ratios, high MCRT or high MLSS rates.

They can reduce turbidity and BOD and control slime growth that can lead to anaerobic conditions. They graze on the floc structure and increase oxygen penetration.

Worms

The picture on the left is 100x Phase Contrast

This is a nematode

Worms are free living macroinvertebrates. They usually indicate very old sludge, high MLSS, low F/M ratios or high MCRT. They crop bacterial populations and recycle nutrients. Nematodes and bristle worms are the most common worms found in wastewater systems.

Bristle worms can sometimes indicate high nitrates and turn the entire system pink.
