Effect of Operational Conditions on Performance of Deep Sand Filter in Turbidity Removal - Juniper publishers

Journal of Trends in Technical and Scientific Research Abstract In this study, laboratory pilot plant was constructed to study the performance of deep sand filter in water treatment. Sand was used as a filtration media under different filtration rates ranged from 4 m/hr to 8 m/hr. Down flow was applied to the filter through sand media with size of 0.7-1.0 mm, while sand depth was changed from 80 cm to 140 cm. The used synthetic turbid water was prepared in different turbidity levels varying from 10 to 30 NTU. Aluminum sulfate (alum) was used as coagulant in different doses varied from 20 to 40 mg/l. Turbidity removal and head loss were investigated as functions of sand depth, filtration rate, alum dose and influent turbidity. From analysis of the experimental results, it was found that the changing of operational conditions (changing media depth, filtration rate, alum dose and influent turbidity) have significant impact on the turbidity removal efficiency, head...

Definitions of the Degree of the Potential Erosion Danger of the Mountain Brown Soil of Azerbaijan Authored by RAE ZH Aliyev On plots of fields under crops under crops, the signs on which it is possible to determine the degree of erosion of soils are the inside covering and plant heights. With the enthusiasm of the steepness of the slopes, the possibility of using cultivated crops as indicators of soil erosion decreases. The degree of soil washout period of natural forage lands can be assessed on the basis of the dependence of the existing between the plant stand and the degree of soil erosion. Strongly eroded soil of slope meadows can be recognized by ecological care regimes of habitats of vegetation. To Read More ... PHP in Trends in Technical & Scientific Research in Juniper Publishers

  Trends in Technical & Scientific Research - Juniper Publishers   Abstract On plots of fields under crops under crops, the signs on which it is possible to determine the degree of erosion of soils are the inside covering and plant heights. With the enthusiasm of the steepness of the slopes, the possibility of using cultivated crops as indicators of soil erosion decreases. The degree of soil washout period of natural forage lands can be assessed on the basis of the dependence of the existing between the plant stand and the degree of soil erosion. Strongly eroded soil of slope meadows can be recognized by ecological care regimes of habitats of vegetation. Keywords: Eroded; Humus; Medium-washed; Bioclimatic; Dense ground-cenoses; Steppe Introduction In the context of Azerbaijan, the process of erosion has become a large development, calling for a washout, erosion and deflation, etc. types of unwanted conseq...
