Ciliates, the most significant group of protists within the ecosystem of biological reactors of sewage treatment plants, can be divided into crawling and sessile ciliates that are associated with flocs and, swimming ciliates that move freely in the mixed liquor.
Species of Prostomatids, usually free-swimming ciliates, are scarce in activated sludge WWTP, they do not usually reach high abundances and have never been reported as the dominant population in stable conditions. The aim of this work is to describe a new species of a sessile prostomatid found associated with flocs in the biological reactor.
