Solar Distillation of Saline Water with Particular Regard to Materials Problems

Source

A chief factor controlling the practicability of solar distillation of saline water is the total quantity of power potentially available in sunlight. At the latitude of San Francisco, this is 73 million Btu per acre. Accordingly, assuming 100 per cent utilization of sunlight, the maximum amount of water that could possibly be distilled in one acre is 8110 gal per day. This means that for full operation at capacity of 34 tons per day, all sunlight falling on an area of one acre will have to be used. By use of multiple-effect solar stills, re-using the latent heat of vaporization, the yields can be increased, but the cost of the device is also increased. Inasmuch as the yield is fixed by total amount of solar energy available, it becomes necessary to effect the economies required by practical conditions by using the lowest-cost device possible to cover this acre. This means not only the lowest possible cost from the standpoint of initial installation but also from the standpoint of continued maintenance.
