АНАЛІЗ ЕФЕКТИВНОСТІ ЗАСТОСУВАННЯ РОТОРНИХ АЕРАТОРІВ ПРИ ОЧИЩЕННІ ВОДИ У СИСТЕМАХ З ОБОРОТНИМ ВОДОПОСТАЧАННЯМ

Purpose of the research is to substantiate the feasibility of rotary type aerators usage at biological water treatment plants with recirculation. Methodology. The main advantages and disadvantages of alternative aeration systems in recirculating aquaculture systems are determined on the basis of the devices technical characteristics and observations results. Determination of the rotor type aerator performance on dissolved oxygen was carried out under conditions of a laboratory experiment using rotary-type aeration. Findings. The paper substantiates the efficiency of rotary aerators for ensuring the proper oxygen regime for water treatment. The scheme of aerator connection the block of biological water treatment facilities was proposed and the rational operational parameters at the coefficient of recirculation at the farm were determined within the limits of 90-97%. Originality. The efficiency of rotor-type aeration systems for oxygen saturation of reversible water has been proved. Practical value. The usage of a rotary aerator will reduce the energy consumption and the heat loss compared to pneumatic aeration systems. [ABSTRACT FROM AUTHOR]
