The high cost of chemical coagulants and their accessibility for water treatment makes most people in rural community to resort to readily available surface water which are usually of low quality exposing them to different ...
A mathematical model was developed to describe the heat and moisture transport pro
cesses occurring in the convective drying of injera. The numerical systems of heat and
moisture partial differential equations (PDEs) ...
Postharvest loss of tomato is high globally as well as locally in Ethiopia. The losses are due to physiological changes, microbial spoilage, mechanical injuries, and lack of suitable handling and storage mechanisms. In ...
The majority of the antimicrobial compounds used for treating textiles are synthetic based and are not considered to be environmentally friend. Therefore, solanum incanum fruit and onion peel were selected for the current ...
In this study, waste corrugated cardboard (WCC) was selected as a feedstock to prepare carboxymethyl cellulose. Compositions of untreated WCC were α-cellulose 63.09±0.985%, hemicellulose 10.85±0.924% and lignin 11.92±0.351%. ...
This research mainly studies the effect of potato peel phenolic compound on cow butter as a preserving agent. It was extracted from potato peel (solanium tuberosom species) waste which delays spoilage and oxidation of most ...
This study was devoted to investigating the performance of Unplasticized polyvinyl chloride (UPVC) pipe filled with alumina (Al2O3) and comparing with calcium carbonate (CaCO3) filler at different weight fractions. In ...
The aim of this research is to examine the performance of clarification unit at Wonji-Shoa sugar factory and setting optimum values for main clarifying reagents to improve the efficiency of clarification plant. The performance ...
Water plays major role in the day-to-day activities of the societies and other living things.
However, fresh water is becoming polluted due to increased discharge from
manufacturing industries in the form of effluents ...
The growth in various types of industries together with population growth has resulted in enormous
increase in production of various types of waste plastic materials worldwide. This creates a problem on
the disposal ...
Sandy soil has large particles which take up a lot of physical space and hence does not bind water. Amending such type of soil using soluble fertilizer leads to water pollution. Furthermore, Nitrogen fertilizers such as ...
Background: The first two years of a child’s life is a critical window during which the foundations for healthy growth and development are built. An estimated 32% of children less than 5 years of age in developing countries ...
The study was conducted at Guna Spring Water Bottling Factory in Kimir Dingai, Farta Woreda, found in South Gondar Administrative Zone of the Amhara Region, Ethiopia. The altitude of the area is 4300m above sea level in ...
A mixed mode solar cabinet dryer that can be used for potato slice drying was constructed and evaluated. The dryer mainly consists of a solar collector/absorber, drying chamber and chimney. The solar collector is made up ...
Generations of plastic wastes are increasing in alarming rate in recent years and became series
environmental problems for both developed and developing countries. The best way to deal with
these wastes is to recycle and ...
Anaerobic digestion is a process in which microorganisms break down biodegradable substrates in the
absence of oxygen. It can be used to treat various organic wastes and recover bio-energy in the form of
biogas, which ...
Chromium(VI) discharge to the environment is becoming great concern for world. Even though there are enormous techniques for removal of chromium(VI), there is still a huge gap on alleviating the problem. Therefore, introducing ...
In many parts of the world, fluoride in drinking water is responsible for notable public health
issues. The presence of a small amount of fluoride in drinking water is beneficial to human health
but a high amount (>1.5 ...
Biomass is one of the most clean and renewable energy resources. Researchers give more and more attentions to the biomass because it can effectively reduce the amount of greenhouse effect due to its zero emission of carbon ...
