Often we do microscopic exams to identify filaments and other causes of bulking. In general, the reports give information on the top filaments or bulking agents and the conditions associated with their dominance in biomass. What is not often done is to take a step back and look at the ecology associated with the increased populations of filaments or high levels of viscous polymers that cause bulking.
What is interesting is that the causes of both filaments and viscous bulking are similar - it is just the mix of factors that determines if the system experiences which problem and to what extent.
The most common factors are:
