Abstract
Many industries depend on the characteristics of the fluid flow through porous media, Such industries are Petroleum drilling, treatment of industrial waste water, etc. Increasing the flow rate of the fluid is important to decrease the cost and increase the production rate.
The present investigation is concerned with increasing of the flow
rate of fluid and studying the behavior of the fluid through porous media, that study requires establishing two systems; a laboratory scale system and a packed bed system.
The laboratory scale system is used at the beginning of the study to study the effect of adding some agricultural wastes on the flow rate of fluid through porous cake. The agricultural wastes used are Bagasse, Okra, chopped Straw, Potatoes peel and Jaw’s Mallow sticks. The effect of different parameters is studied. Such parametersare: pressure difference, slurry concentration and additives concentration.
Comparison between the data obtained from the study of the different parameter was made to determine the best type and concentration of the additive which gives the best flow rate of the filtrate.
This investigation is concerned also with obtaining an mathematical models for the best concentration of each type of the agricultural wastes used. These models relate the volume collected with time and are dependent on the pressure difference and slurry concentration.
