Abstract
Access to potable water to the people is narrowing down day after day all over the world. Most of the human diseases are caused by polluted or non-purified water resources. Water purification without affecting the ecosystem is the necessity of the hour. Solar distillation is one of the water purification techniques producing ultrapure distilled water. Solar still distillation systems offer sustainable tools for freshwater production. Numerous environmental and operational parameters attribute to optimize the still design. Different designs were tested by researchers to improve the productivity of solar still. In their experimentations, the solar still integrated with external or internal condenser is deemed to be effective and efficient design. In this detailed survey, we are seeking to introduce, explain and discuss the status of different solar stills integrated with different condensers arrangements. (C) 2016 Elsevier Ltd.
