Use of a new technique of nano-fluids to increase the solar still productivity

Abstract

Potable water is essential to life. The supply of fresh water is becoming an increasingly important issue in many areas of the world especially. In remote and arid areas in Algeria. Among the non-conventional methods to desalinate brackish water or seawater, is solar distillation. The present study aims to improve the solar still performance, and to increase its yield. In this paper a new kind of technology, Nano particles( ZnO) different weight (10, 20, 30 and 40g) were added to the basin solar still and optimal depths water 1cm .to augmentation heat transfer and the productivity. The distillation performance experimentation has been conducted at the in Ouargla University, The conventional still yields 288 ml/m2and the test still with added 40 g Zinc Oxide produces 325 ml/m2 in a day. The still with Zinc Oxide (ZnO) has 13.02 % higher production compared with conventional still.
