BIological Treatment - Aeration Systems for Nitrification and Denitrificattion
Aeration system EKOMVO is used for aeration and hydraulic agitation of tankages, especially at communal and industrial waste water treatment plants, eventually at intensive fish farming. Oxygen transfer into waste water is done by suitable aeration membrane with fine-buble or medium-buble perforation, according to need. Membrane material is modified polyurethan, especially resistant agains microorganisms and hydrolysis influences. Intensive aeration is necessary at biological waste water treatment to ensure sufficient quantity of air for microorganisms biomass, which decompose waste water contaminants and ensure puryfying effect by its metabolic activity. Membrane by itself is made in such thickness, to ensure long-term operating life and at the same time to be characterized by high oxygen transfer into waste water ability. These parameters, in combination with using of suitable anchorage and fixation materials, guarantee long-term operating life.
EKOMVO system is suitable not only at new waste water treatment plants construction and realization, but also at existing treatment arrangements reconstructions or their intensification.
Indispensable factor at their setting is also very easy montage and subsequent maintaining. These aeration systems doesn`t require acid flushes and thank to their self-devatering construction doesn`t need montage of additional drainage system for condensate removal. Condensate is drived out system to tank space in operation by operation air.
Anchorage system by itself (polypropylene grids) practically exempt from operational detrition, their operating life exceed moral operating life of system, producer suggests replacement of aeration membrane after c. five-year continuous operation. After that period change of oxygen recovery factor curve happens and it will subsequently take effect in increased consumption of operational electric energy, which is necessary to ensure air blowers operation.
