Page: 1 Long sand trap
Long sand traps are constructed as elongated, open channels in two parts in small plants (in three or more parts in larger plants). Baffle plates at the sand trap outflow are used to maintain the desired flow speed when inflow varies. The sand ...

Page: 2 Round sand trap
round sand trap, the waste water is introduced at the periphery, as a result of which a cyclic flow is produced and the deposited sand is displaced towards a funnel in the centre of the basin (teacup effect), where it can also be washed and is conveyed to a dehydration apparatus with a compressed air ...

Page: 3 Aerated sand trap
wider and deeper than the long sand trap and therefore also unaffected by varying inflow. It is mainly used in larger plants. The horizontal waste water flow speed is therefore much less than 0.3 m/s. It should reach approx. 0.3 ...

Page: 3 Sand trap
Sand traps are intended to separate out all coarse and fine sand particles but also other granular material such as ash, bed load or debris so that the subsequent purification process is not hampered. To this end, the flow speed of the waste water is reduced from ...
