Ciliates, predators of flakes

Ciliates, predators of flakes

They are flattened dorsoventrally microorganisms that crawl around the biological flakes, scraping the surface of bacteria clusters with organic materials, ingesting flakes fragments and thereby contributing to the rounded appearance of an ideal flake. The cilia are modified and grouped in the part that is in contact with the substrate, forming "little legs" with which they move on the flake surface. Its prevalence in a system indicates nitrification and good operation of the plant with well formed flakes or in process phase.
