%X In biological wastewater treatment plants, the right selection of an aerator is one of the most important elements. The choice of the aerator must take in account its performance 每 dissolved oxygen content per unit of energy consumed, oxidative capacity and supply of the required amount of air so that the required concentration of oxygen is saturated properly. The experiments have been conducted carefully examining the efficiency of the selected deep每cavitation aerator operating without the aerator tip or with attached two and three每blade tips. The performed investigation included air dispersion methods of opposite ejecting for determining air flow, flow pressure and dependence of vibration on different placement of the aerator under varying positions of corners. It has been established that compared to air ejecting flow, changes in pressure and vibration are most significantly influenced by a deep每cavitation aerator having a three每blade tip.Article in Lithuanian
