"Graduation tower"
A graduation tower consists of a wooden wall-like frame which is stuffed with bundles of brushwood. It increases the concentration of a solution of mineral salts. The salty water runs down the tower, and — through the action of breeze and sun — partly evaporates; at the same time certain mineral content of the solution are left behind on the sticks of brushwood.
