Eco-Friendly Water Purification Through Solar Energy and Post Treated Water Analysis

Abstract

Water is one of the natural resources which sustains life on earth. The total water resources on the earth are around 1360 million cubic kilometres. The water resources available to humanity can be classified as surface and sub-surface water resources. Surface waters include the permanently or intermittently occurring inland waters on the earth's surface, either in liquid or solid conditions. Nowadays, many water resources are polluted by anthropogenic sources, including household and industrial processes. As the population of cities and towns grows, the demand for clean water increases. However, this demand often exceeds the available supply of freshwater resources, leading to the use of alternative sources such as raw water, i.e. Chemical coagulation, adsorption, activated sludge, have been applied to remove pollution. However, there are still some limitations especially that of high operation costs.The treatment of raw water involves several stages of removing impurities and contaminants to make it suitable to be discharged back to the environment. Accessing to clean water is a critical issue worldwide, particularly in developing countries where many people do not have access to safe drinking water. Solar water treatment plants offer a solution to this problem by providing a sustainable and cost-effective way to purify water. These plants are typically located in areas with abundant sunlight, making them ideal for countries with a warm and sunny climate. Water treatment system suppliers use a combination of solar panels and water treatment equipment to purify water from natural sources like sea, river, lakes, ponds, etc... In this paper, we will establish a mini-solar water treatment plant and purify different water samples obtained from the above-mentioned natural sources. Analysis and interpretation of results will show the suitability of the above-treated water for drinking and other purposes.
