Expanding electricity access and energy in rural area in center of Mozambique is a challenge. Microhydropower plant is one of the solutions to provide electricity. However, selecting the power plant size and the turbine type in designing hydropower system is critical. Giving specific site characteristics of head and flow to find specific turbine is necessary to select appropriate turbine. The main objective of this paper is to develop a methodology to select the best turbine that can be used in the micro-hydropower plant at Chimenza river - Manica in Mozambique. Flow duration curve and exceedance probability equation was successfully used to characterize the water flow of the river. The accurate measurement of the head and flow discharge will determine the best type of power plant size and turbine type. According to the result, the optimum flow was 0.29 m3 /s combined with the head. The appropriate turbine for this scheme is Pelton type with an efficiency of 0.85% and the power capacity will be 157.2 kW.

Nowadays, the main application of coal mine in the world is to produce energy through thermoelectric power plants. Energy generation is always associated with the production of enormous amounts of ashes, both bottom and fly ashes. The main objective of this work is to study the effect of time, temperate and concentration on Synthetic zeolites produced from utilizing minerals of coal bottom ash. However, for the factor significance analysis, factorial planning of two levels and three factors was used, where eight experiments were obtained, and the results of FTIR transmittance showed favorable variation in time and temperature, and the variation of the NaOH concentration was not significant. It was concluded that the concentration of NaOH only influences the zeolites formation when combined with the crystallization time.

Reusing of 3.3 MCM (million cubic meter) of water every year from utilizing thermal water of the hot springs will boost the availability of water at the Dead Sea area. This water represent an additional sources of water for agribusiness in which all available springs and similar sources can follow the same way of successful. In this work the water quality of Afra hot springs was analysed at source and compared with the water at downstream at the Dead Sea area. Microbial analysis found no traces for faecal coliform and E.coli bacteria which lower the risk for contract diseases when the water is used for irrigation without any prior treatment. The water at upstream rich with high trace of metals with a significant content of bicarbonate, BOD5 and COD but within Jordanian standards for irrigation purposes. Slight variations between physicochemical parameters and trace metal contents found between the water from the source and the water at the downstream because of surface runoff interactions at the way down. Afra spring water at the source is considered as low-enthalpy geothermal sources, as the temperature is range between 45-48 oC, therefore, power generation is unlikely to be possible. However, it can be used in curative water tourist. According to the water quality and availability, different suggestions for treatment and uses will be defined in this paper. Furthermore, to evaluate the potential uses at the downstream
