OXYGEN INCREASE ON MODIFIED PADDLE WHEEL OF MARINE AND FISHERIES POLYTECHNIC OF SIDOARJO
One type of aeration device is a paddle wheel which is the most common aerator used for aquaculture ponds (Wyban et al. 1989; Moore & Whitis 1999; Laksitanonta et al., 2003). The aeration rate is influenced by the surface area of water and air contact, the difference of oxygen concentration, co...

| description | One type of aeration device is a paddle wheel which is the most common aerator used for aquaculture ponds (Wyban et al. 1989; Moore & Whitis 1999; Laksitanonta et al., 2003).
The aeration rate is influenced by the surface area of water and air contact, the difference of oxygen concentration, coating film coefficient and turbulence (Boyd 1998) The geometry, and speed of the spin mill affect aeration performance (Peterson & Walker 2002; Moulick et al., 2002). Aerator performance is an important factor in the selection and use of aerators as they relate to investment and operational costs, so that the development of aerator design and improved operating performance is still possible to do. The purpose of this research is to know the comparison of paddle wheel performance result of modified design versus paddle wheels manufacturer. The research was designed with 2 (two) different types of paddle wheel which is the treatment of 1 (one) paddle wheel from the modified of construction design with a power of 0.37 kwh-1 0.5 hp and the treatment of 2 (two) artificial paddle wheel from manufacturer with 0.78 kwh-1 1 hp. Statistical analysis use T-test. The results of research is modified Paddle wheel (Treatment 1) was increased of DO = 2.56 ppm; Coverage area = 418929,6 cm2; diameter bursts= 132.2 cm. Conventional paddle wheel performance (treatment 2) was increased of DO = 2.54 ppm; Coverage area = 41983,8 cm2; The diameter of the bursts is 130.2cm. The t test results (statistic) on all variables showed no significant different (p= 0.595). This means the performance of the modified paddle wheel with 0.37 KWh-1 0.5 hp one phase is the same as the conventional paddle wheel performance with 0.78KWh-1 1 hp two phase power but there are energy saving 0.41 KWh-1. |
