The biological filtration is done very efficiently by a thin hard biofilm which is created on the ,sand, particles. Because the ,sand, particle are so small the surface area of these filters is simply staggering. But they are not practical for the home aquarium. ,Sand, filters of very large capacity for pools are cheap, $250 (2,100 GPH) to $350 (4,500 GPH).

In any case, bar screening prior to the ,pumping, station are considered as a pretreatment step. Bars bars must have a minimum thickness like: Bar spacing of 40 mm: thickness between 12 and 25 mm. Bar spacing of 20 mm: thickness between 6 and 12 mm.

Adopt Rankine's earth pressure theory and the partial factors for loads and materials as given in Geoguide 1 in your review. Unit weight of water Yw and ,sand, yb are 9.8 kN/m' and 19.8 kN/mº respectively, shear strength ,parameters of sand, are c' = 0 kPa, Ø' = 41.1º. Allow a uniformly distributed vertical surcharge load of 6 kPa acting at GL.

For sand the underflow will typically be about 80% solids, almost dry enough to convey. Most operators mount these on a tower to make a pile and then allow the sand to drain further. Screw classifiers will produce sand at about the same % solids and are probably a lot more forgiving in operation, especially with coarse sand (+150 microns).

Pumping, cement into a slot placed some distance along the casing could also be used, but was not attempted during the Douglas trials. Slotting of the casing using the abrasive jet proved to be relative easy. With the pressures available, it took several bags ,of sand, and some 4-10 minutes of ,pumping, to cut a circular slot in the steel casing.

A device for use inside casing to control ,sand, from enter-ing perforation tunnels is also becoming available. Mr Baker explain ed that ,sand, control media-filled telescoping devices connect the reservoir face to the production liner without explosive perforating charges, providing reliable full-bore ,sand, control without gravel packing.
