ABSTRACT:
In the separation of solids out of a flushing liquid such as used in flushing out boreholes and the like drilled or cut in rock, concrete, masonry and similar materials, a flocculant is added to the flushing liquid before it enters a settling tank so that the removal of the solids is accelerated. As a result, a supply of flushing liquid, free from solids, is always available from the settling tank. The flushing liquid flow is directed through the feed line into the settling tank. Before the liquid enters the settling tank it is passed in contact with a flocculant so that the liquid picks up a dosed quantity of the flocculant. To assure the optimum effect, after contacting the flocculant, the liquid is mixed and then passed into the settling tank.
