A moderate amount of water creates the capillary attraction that allows sand particles to clump together. This is what allows you to build sand castles. But beach sand could easily become quicksand if enough salt water were thrust up through it. If an excessive amount of water flows through the densely packed wet sand, it forces the …

By allowing the fat, grease and oil (FOG) to cool, a grease trap is able to separate the different layers of wastes with water. FOG are lighter in density and float at the surface of the tanks, and the cooled water – minus the FOG - continues draining to the sewer system. FOG float to the top of the water are then trapped by the grease trap.

Tractor. L3830 03: RTV 900. In this part of the country just sand does not work well because the wind blows it away. We have to use a salt/sand mix to keep the salt/sand in place. Also it keeps the sand from freezing when store out side and under cover. Cover keeps the rain from washing the salt out.

Desanders are hydrocyclones larger than 5″ in diameter (6″, 8″, 10″ or 12″ I.D.). Generally, the smaller the cone, the smaller size particles the cone will separate. Desanders are primarily used to remove the high volumes of solids associated with extremely fast drilling of a large diameter hole, especially when a fine screen shaker ...
