Techniques for Extracting Pure Water from Atmospheric Air by a Solar Collector and Absorbent Materials: Recent Advances and Development

Abstract

Because air is a clean, renewable source of water that is available everywhere, air extraction is regarded as one of the key means of supplying fresh water. Many researchers have looked into this issue. These investigations may be divided into two major categories. While the second group researches the direct absorption-regeneration of moisture from air, the first group works with the of air. This paper presents and explores previous theoretical and experimental works and study on the topic of extracting pure water from air and using different absorbent substances to absorb water vapor from the atmosphere. The fundamentals and improvements to the topic of pure water extraction and its great benefit were the use of different elements and materials when designing a prototype in the main components of the extraction systems. Drinking water is generated from the air by solar panels using solar energy and heat during the day. It has been discovered that some desiccant materials with good water absorbers, such as calcium chloride and silica gel, may be successfully utilized in the processes of extracting drinking water from ambient air by creating suitable designs. It has been demonstrated that using solar energy may change the high ambient air temperature, a primary cause of water scarcity, into a benefit.
