The Effect of Nutritional Conditions on Floc Formation in Zoogloea ramigera.

The formation of bacterial flocs is of crucial importance in the activated sludge process of biological system, treatment waste treatment. In such a generally begins with the settling of large suspended solids from the influent wastewater. The liquid is then channeled into the reaction basin where soluble organic compounds undergo degradation, which is primarily accomplished by the metabolic activity of bacteria, though fungi, algae and protozoa may contribute to the process. Vigorous agitation facilitates contact between substrate molecules and microbes, and aeration maintains the necessary oxygen tension to sustain the aerobic organisms pertinent to the process. During this stage of treatment, bacteria aggregate in dense macroscopic flocs in which small suspended solids and dissolved substances become entrapped. Microbial growth, re reflected by an increase in biomass, occurs as a result of the removal of organic compounds.
