OPERATION OF FACILITIES WITH FREE-FLOATING BIOCENOSIS IN THE FIELD OF WATER BIOTECHNOLOGY

Abstract

A classification of facilities utilizing free-floating biocenosis is presented, along with an analysis of the functional roles of each component. In particular, the roles of nitrifying bacteria (Nitrosomonas, Nitrobacter), carbon filamentous bacteria (Sphaerotilus, Beggiatoa, Thiothrix, Microthrix), yeasts (genera Candida, Torulopsis, Trichosporon, Rhodotorula), and protozoa are examined.The aim of the study is to identify the main challenges that arise during the operation of facilities with free-floating biocenosis and define the ways to solve them. The study outlines the principal tasks and stages of operating biological treatment facilities. It includes a structured list of procedures required during the stages of commissioning, routine operation, scheduled  inspections, and preventive maintenance of aeration tanks.The research paper highlights the crucial problems that arise in the course of operation of biological treatment facilities with freefloating biocenosis, namely the causes of activated sludge bulking and foam formation, and proposes effective strategies for their elimination. Furthermore, it identifies the causes of the development of filamentous microorganisms that serve as  ndicators of sludge bulking. The work provides an overview of activities necessary for both managing the treatment processes and conducting technological monitoring of aeration tank operations.
