Abstract

The operation of the Water Treatment Plant (WTP) requires electrical energy to drive chemical systems, namely dossing pumps and chemical mixers and lighting lamps. In WTP, most of the gravity systems are located far from settlements and most of the access roads are quite difficult, and there is no electricity network available from PLN, whereas if using a machine, the supply and transportation of fuel oil is not easy, this gives result in the WTP that is being built only to function as a pre-sedimentation tank, so that the quality of water delivered to customers especially in the rainy season is still cloudy. This requires a solution to supply energy that is not fuel dependent, easy and inexpensive so that the price of water production also decreases with good water quality. The remaining press of water flowing from the intake to the WTP is above 3 bars on average, so it still has the potential to be used to generate electricity by installing micro hydro, so that water energy before entering the WTP can generate electricity. The point is that water energy is used to produce electrical energy to process water itself (from water for water). The working principle of micro hydro is the same as micro hydro in general, but because the fast pipe used is the transmission pipe with the installation system not always straight and the average distance above 3 km, it is necessary to do hydraulic study to determine the micro hydro capacity that will be installed. Installation of micro hydro in water treatment plants must have a minimum head of 30 meters (already reduced by head losses). Micro Hydro for WTP is designed with power capacity that is suitable for the needs of electrical energy in WTP, namely 3 kW, 5 kW, 7.5 kW and 10 kW, 12.5 kW, 30 kW, 50 kW and can be more if the results of technical calculations can produce more electricity than that. While the capacity of the WTP that can be installed micro hydro is between 5 liters / second - 200 liters / second, but it can also be used for capacities above 200 liters / second with specifications and special treatment. Based on the study review, it can be seen that the use of micro hydro in water treatment systems is very appropriate in providing cheap and environmentally friendly energy to meet the electricity needs of WTP.
