Background: Coffee is the foundation of Ethiopia’s economy, but the wastewater generated by coffee processing cannot be properly treated, therefore, causing various environmental problems. Methods: In this research, electrochemical oxidation(ECO) and photo electrochemical oxidation(PECO) are combined with UV and hydrogen peroxide (UV/H2O2) to reduc...

The amount of pressure and age of the water were higher at low demand periods than at peak demand. One way to see how well a distribution system works is to look at how much pressure and how old the water is. Through optimization, pressure can be kept at an optimum level in the distribution system. Subsequent monitoring is very important for the su...

Water quality, whether utilized for home, irrigation, or recreational reasons, is crucial for health in both developing and developed countries around the world. For the treatment of nitrate (NO3) and phosphate (PO3) from coffee processing wastewater, photoelectrochemical oxidation was used. This process is mainly used to destroy pollutants through...

The elimination of organic compounds in coffee processing effluent utilizing electrochemical oxidation (ECO) as well as a combination of electrochemical oxidation (ECO) and ultraviolet and hydrogen peroxide (UV/H2O2) was explored. Then, the percentage reduction of chemical oxygen demand (COD) was investigated. The effect of different experimental f...

The hybrid treatment processes are one of the hot topics in wastewater and industrial effluent treatment, especially in the highly polluted wastewater can be treated effectively using the combined processes. The present study is to treat the wastewater using a hybrid sono-electrocoagulation process (SEC), and the effects of operating parameters suc...

Soil loss is one of the most important concerns that experts are looking into for successful watershed management. The goal of this research is to use a modeling approach to estimate the spatial sediment yield and identify hotspot locations at the sub-watershed level within the Finca'aa watershed in the Abay River Basin, Ethiopia, from 1999 to 2017...

Ozonation is one of the most effective and efficient advanced oxidation processes (AOPs) and has shown great potential in the treatment of industrial effluent and wastewater. In the present work, the ozone-Fenton process for % COD and color removal together with electrical energy per order (EE/O) determination for distillery industrial wastewater (...

Rainfall-runoff modeling is essential for soil and water conservation and for watershed management. The Soil and Water Assessment Tool, SWAT, model was used to predict average annual stream flow and identify vulnerable areas in the Finca'aa watershed at the sub-basin level. Meteorological, land use land cover, LULC, soil, 30 m resolution digital el...

Ethiopia has lost sizable forest resources due to rapid population growth and subsequent increase in the demand for agricultural land and fuel woods. In this study, GIS and remote sensing techniques were used to detect forest cover changes in relation to climate variability in the Kafa zone, southwest Ethiopia. Landsat Thematic Mapper (TM) images o...

Characteristics of watershed were not well investigated as global also in Fincha, Ethiopia. Fincha watershed is the most erosion prone area in the highlands of Ethiopia towards to Fincha dam.Therefore, the aim of this study was toanalysisFincha watershed characteristics based on land use/cover, soil type and slope classification and to identify soi...
