Abstract :A venturi tube or pipe part or device allows air bubbles to be inserted into flowing water from air inlet holes and so increases dissolved oxygen insert ignore into journalissuearticles values(DO); levels in water .  Therefore, the aim of this paper is to evaluate system design and experimental results related to configuration of venturi tube in air vacuum and aeration process. Different aerator modules constructed using venturi tubes  connected in either single or double in parallel insert ignore into journalissuearticles values(with single or double outlet pipe line); were evaluated and compared for their air flowrate, vacuum capacity, oxygen transfer coefficients insert ignore into journalissuearticles values(OTC);, standard oxygen transfer rate insert ignore into journalissuearticles values(SOTR);, and standard oxygenation efficiency insert ignore into journalissuearticles values(SOE); determined by clean water tests.  The experimental results indicated that the double parallel design insert ignore into journalissuearticles values(connected to a single outlet pipe line); generally performed better than the single and double parallel insert ignore into journalissuearticles values(connected to a double outlet pipe line); design in terms of transferring oxygen into water.
