Abstract
This thesis discusses the Dyna-sand filter feasibility to be applied with water variable solids loads to check its applicability for both water and wastewater treatment plants also for agricultural drains water treatment plants and check its realability to be applied as direct filtration and Study the probability to development existing water treatment plants using dyna-sand filter to increase the plant productive capacity with minimum civil work and cost Lab scale pilot was applied under sensytic water with variable solid load to determine its maximum removal efficiency with different filtration rates. all measurement was made according to American standard methods for water and wastewater Examinations. All measurements made on equipment existing in sanitary engineering laboratory in faculty of engineering, Ain Shams University The study resulted the system applicability against all applied variable solid load between TSS (50-250ppm) with variable rate of filtration between (200-500m3/m2/d) with inversely proportional between them, with removal ratio variable between (85% up to 95%).
The feasibility of the system to be applied for up grading the existing water treatment plants by replacing the mechanical equipment of rapid sand filter with dyna sand mechanical equipment that increase the area production by (2-3) times the of existing plants and decrease the required cost for constructing new plants to 10%.
