Sludge drying bed (SDB) is the most widely used method for sludge dewatering. Sludge drying involves natural ways of drying to mechanical ways of removing water content. SDB is generally used for small and medium sized communities (TCHOBANOGLOUS et al. 2003). The selection of the technology will depend upon land availability, climatic factors, the quantity and composition of the sludge.
Whenever possible, well graded granular materials, such as coarse sand, should be used for fill construction. For a detailed discussion of grading requirements for filter materials the reader is referred to the Earth Manual published by the U.S. Department of the Interior (1974).

sand are shown in Figure 1, it shows that HST 60 sand and the building sand lie within the grading limits of the code, but nearer the fine limit. The building sand is just coarser than the HST 60 sand. While the other model sand, HST 95, has a grading that is finer than the fine limit set by the code. The grading of all the sands shows

· Soil selection is one of the most important functions of the grading inspector. The grade is the foundation for the roadway. The materials selected as a foundation should be the best available. For most grading projects, a soil survey has been made prior to design to determine what kinds of soil will be uncovered at or near grade line.

Both the position and the shape of the grading curve for a soil can aid its identity and description. Some typical grading curves are shown in the figure: A - a poorly-graded medium SAND (probably estuarine or flood-plain alluvium) B - a well-graded GRAVEL-SAND (i.e. equal amounts of gravel and sand) C - a gap-graded COBBLES-SAND
Typical foundry grade chromite sands will show a weight gain of 0.5 to 1.0 in a standard LOI test. • To avoid oxidation reactions, chromite sands can be heated under an inert atmosphere such as nitrogen. Under these conditions a high quality foundry chromite sand will …
These test methods establish the apparatuses required, standard procedures, and associated calculations for determining the particle size distribution and shape grading of sand in golf course putting green and other sand-based sports field rootzone mixtures assumed to have sand contents of 80 % by weight or greater.
