“…Indonesia itself has a lot of potential energy sources that can be utilized, such as solar energy, which is always available throughout the year. Therefore, modern designs are developed using solar that is used with optimal performance (Suravut et al, 2017). The energy potential of the river flow is very promising as it can be utilized as much as possible to produce electrical energy (Yükse et al, 2008;Yukse, 2010).…”

Undershot waterwheel at low flow with an average discharge of 0.12 m3/s and 613.2 W water horsepower are used to turn the waterwheel. The rotation results obtained with aluminum material is 24 RPM which has a density of 2.71 g/cm3 while the lowest rotation is owned by a galvanic of 20 RPM with a density of 7.49 g/cm3. From the experiment, it was found that the difference between the materials used was due to the different density. The efficiency of waterwheels with aluminum material has the highest value, namely 30%, while the lowest using acrylic material has an efficiency of 23%. For the highest generator efficiency using aluminum material with an efficiency of 4.2%, the second has an efficiency of 3.6% using Aluminum Composite Panel material. Aluminum has the highest efficiency because it has less density than galvanized. In addition, the thickness of aluminum is also very influential, where aluminum has a thickness of 1.14 mm while Galvanized has 0.98 mm.

“…Authors such as Brown & Trucker [11], show that the aeration efficiency by paddle wheel devices is directly related to the increase on the rotation speed and length of the paddles, generating an increase in costs and power required. Low RPMs in paddle aerators favor the volumetric transport of water when compared to conventional methods and equipment [12,13]. At high RPMs, there is a lower oxygen transference due to the volumes of air used and higher energy costs.…”

The reduction of dissolved oxygen (DO) in water is associated with the effect of climate change. The lack of oxygen in water bodies directly affects the biological species present in different shallow water bodies such as swamps and wetlands, as well as in aquaculture processes. An optimal value in the DO concentration favors the reproduction of these biological species present in both artificial and natural environments. For this, various equipment has been developed to favor the increase of DO in the water to acceptable values. However, some of these systems are expensive, energy inefficient, and noisy which generate adverse impacts in aquatic ecosystems due to perturbances in the water. This study measures the efficiency (KgO2·kWh-1) of introducing DO into the water using a paddle wheel aerator system at low RPMs destined for shallow bodies of water. Tests were performed on anoxic water samples using aerators with 6, 12, and 24 paddles at the laboratory level. By increasing the voltage (6, 9, and 12V), the RPMs applied to each device through a geared motor is also increased. The results show a higher DO transfer rate in the 1 and 5 mg of O2·L-1 range. The best configuration concerning energy consumption worked at low RPMs using the 6-paddle wheel aerator at 6V. This establishes that, in addition to the management of low revolutions, the use of a smaller number of wheels favors an increase in efficiency during the DO restoration process in shallow water bodies.
