Poster 36×24, Protozoa as “Bio-indicators” of the “Health” of the Activated Sludge Process
$48
Size 36″ x 24″
The poster is beautifully illustrated with examples of protozoa in each of the major protozoan groups (amoeba, flagellates, free-swimming ciliates, crawling ciliates, stalk ciliates, and tentacle ciliates). The dominant of each group is correlated with operational conditions. The poster also correlates specific protozoa with changes over time in dissolved oxygen concentration, volume of flow, mean cell residence time (MCRT), and organic loading. The saprobic index correlating specific protozoa as “bio-indicators” is provided.
