gravel Screening separates the sand and gravel into different size ranges Water is sprayed onto the material throughout the screening process After screening the sized gravel is transported to stockpiles storage bins or in some cases to crushers by belt conveyors bucket elevators or screw conveyors The sand is freed from clay and

fine sand and materials lighter than water are transported in the water or on the water surface without contact with the river bed This process is called suspension and materials carried in suspension are the suspended loads Suspended load creates the turbidity of stream water Gravel of larger diameter slides or rolls and sand hops or
d Sand traps Sand traps are not normally required at surface water treatment plants Their principal application is for the removal of fine sand from well water The presence of sand in well water is usually a sign of improper well construction or development If sand pumping cannot be stopped by reworking the well the sand must be removed

Slow Sand Filter SSF Slow Sand Filter Operation A bed of sand through which water passes together with Process description necessary structures and control to a pply water to flow and to remove water after filtration Process description At early stage only very little purification
the iron can be removed simply by aerating the water and filtering it through sand and gravel The sand and gravel used in the filters will need to be cleaned periodically Similar problems arise when water has excessive manganese concentrations above 01 mgl the WHO guideline value but again the water can be treated by aeration
Manufactured sand MSand is a substitute of river sand for concrete construction Manufactured sand is produced from hard granite stone by crushing The crushed sand is of cubical shape with grounded edges washed and graded to as a construction material The size of manufactured sand MSand is less than 475mm
Testing of Sand Quality at Construction Site Following are the tests for sand at construction site Organic impurities test – this test is conducted at the field for every 20 cum or part thereof Silt content test – this is also a field test and to be conducted for every 20 cum Particle size distribution – this test can be conducted at site or in laboratory for every 40 cum of sand
