<p>An evaporation apparatus (10) is shown in the form of an inflatable elongate plastic tube (12) that is fitted with fluid control means in the form of an inlet gas fan (14) and a gas outlet hole (16). The capacity of the inlet gas fan (14) and the size of the outlet hole (16) are matched so that the degree of inflation of the tube (12) can be maintained. In use the inflated tube (12) is partially filled with a volume of liquid (18) in a pool at a base thereof to be heated and evaporated by solar radiation and carried out of the tube (12) by a flow of gas therethrough. The pool of liquid (18) may include solid matter (19), or even contain substances such as dissolved solids or salts. Over time a significant quantity of this material can become deposited in the tube (12), and can be reclaimed.</p> |
