Wastewater from a mahewu processing plant was collected for characterisation and jar testing using Ferrifloc 1820 and a combination of Ferrifloc 1820 and the polyelectrolyte Magnafloc. Treatment showed that Ferrifloc 1820 caused a statistically significant decrease on both the chemical oxygen demand (COD) and oil and grease content of the wastewater. The mean decrease for the COD using Ferrifloc 1820 was 65.24%... Read more.

Two models for raindrop growth in clouds are developed and compared with an interpretation to elucidate the rain drop relationship among both the models. A continuous accretion model is solved numerically for drop growth from 20 to 50 microns, using a polynomial approximation to the collection kernel, and is shown to underestimate growth rates. A Monte Carlo simulation for stochastic growth have also been implemented to... Read more.

Water resources play an important role in the development of the socio-economic status of a country. The world’s population increased from one billion to six billions in less than 200 years. With the rapid increase in population and advancement in technology, demand for water increases steadily and the limited amount of available fresh water sources are subjected to severe environmental problems. Available fresh... Read more.

Awash River is the main irrigation water source for mechanized farms and small land farmers established in the Basin for the last few decades. Recently, with the rise of Beseka Lake, the amount of discharging rate into the Awash has been a serious concern to Agricultural Production in the Middle and Lower Awash Areas. This study was conducted to evaluate the effects of Beseka Lake on irrigation water quality, soil... Read more.

Water makes the difference between living and non-living things, base on this there is a strong need to look at the chemistry, to make sure that it is free from contamination because of chemical reaction that take place in the living cell. In the case of this study, it is critical to determine the quality of the water supplied, because of the chemical reaction. This study analyzes 10 representative well water systems... Read more.
