    Abstract

    A study of oxygen transfer is develop to investigate the correlation of diffuser type (tube diffuser) to oxygen transfer in a liquid using four various of diffuser type; one line, four crosswise, eight crosswise and combine of four crosswise with four square. Tube diameter is 0,5 inch, 80 cm of length, with diameter of pressure stabilizer is 10 cm. Each tube consists of 24’s holes (diameter 0,5 mm each). Oxygen transfer is conducted in a tank using 500 liter of tap water. Air flow-rate applied is 17,43 liter per minute. The study shown one line diffuser give Kla = 2,27/hr, oxygen transfer efficiency 3,05 %, linier equation ln(Cs-Ct)=2,193-2,27t and coefficient of regression r = -0,99; four crosswise tube diffuser give Kla = 2,25/hr, oxygen transfer efficiency 3,03 %, linier equation ln(Cs-Ct)=2,161-2,25t and coefficient of regression r = -1; eigth crosswise diffuser give Kla = 1,614/hr, oxygen transfer efficiency 2,09 %, linier equation ln(Cs-Ct)=2,044-1,614t and coefficient of regression r = -0,99; combination of four crosswise with four squaretube diffuser diffuser give Kla = 1,80/hr, oxygen transfer efficiency 2,80 %, linier equation ln(Cs-Ct)=2,02-1,80t and coefficient of regression r = -0,90.
