EVAPORATION REDUCED
A new chemical process will help reduce djam and reservoir losses in the drier parts of Australia, a serious problem for the farmer in the hot summer months. The Commonwealth Scientific and Industrial Research Organisation has developed the process in recent research. It has carried out extensive tests in different parts of the country and estimates that the process will save a quarter of the water in dams. The process, known as the Mansfield process, uses beads of an insoluble chemical known as hexadeconal to restrict evaporation.
The hexadeconal floats on the surface of a dam and is anchored on a special raft to prevent it blowing away. A very thin invisible film spreads from the beads over the surface of the water and this in turn restricts evaporation.
