Cold Water Purifier Without Electricity
Water is a fundamental need to all the organism. Life on earth started with water and sustains because of the water. One-third of the earth's surface is surrounded by water and most of the water is in the form of seawater that is not potable and rests in the ice caps. About 2-3% of water is in the form of fresh water is available for human needs.

Water Pollution

The contamination of water bodies due to human activities has caused water pollution. Water pollution is used to define the change in the physical, chemical, and biological properties of the water, and the pollutant which is responsible for pollution is called the water pollutant.

Water purification is a process that is used to remove the impurities present in the water. Water contains several impurities such as physical, chemical, and biological contaminants. Hence the water purification process removes undesirable contaminants, biological impurities, suspended solids, and gases from the water.
