Active sludge contains four groups of protozoa: sarcodic, flagellate, ciliate infusoria, and suctorians, which absorb large amounts of bacteria thus controlling their optimal number.
The presence of peritrichous colonial ciliates identified as Epistylis and Vorticella spp., and suctorians identified as Acineta and Tokophrya spp., occurring as ectocommensals or epibionts was confirmed.
