Water Purification Safe drinking water is essential to every living being. Access to safe drinking water has improved over the past years, but still approximately one billion people are deprived of safe and clean water. Over 2.5 billion people have no access to adequate sanitation. A report, issued in November 2009, suggests that by 2030, in some developing regions of the world, water demand will exceed supply by 50% and approximately 70% of the fresh water used by humans goes to agriculture. People are using more and more materials that are polluting the water sources that one drinks from. In nine of the last ten years, large blue-green algae blooms have appeared on the northern part of Lake Winnipeg. These are caused by excess phosphorus …show more content…

People are using more and more materials that are polluting the water sources that one drinks from. In nine of the last ten years, large blue-green algae blooms have appeared on the northern part of Lake Winnipeg. These are caused by excess phosphorus in the water. Fertilizer use is 15 times higher today than it was in 1945. Beach closures are becoming increasingly common.
The list of pollutants is long, and the signs of water pollution surround people, but the point is that these people are dumping contaminants into the small portion of water on the planet that is fit for drinking. When more and more people, especially the once in developing countries, found it hard to get clean drinking water, the business world has, therefore, entered this market too and made a profit out of it as well. Running this type of business can be a profitable way of enhancing the quality of life and health of people.
The businesses sector can be divided into 2 basic categories: Water Filter and Purifier

Water filtration is the process of removing undesirable chemicals, biological contaminants, suspended solids and gases from water. The goal is to produce water fit for a specific purpose. Most water is disinfected for human consumption,but water purification may also be designed for a variety of other purposes, including fulfilling the requirements of medical, pharmacological, chemical and industrial applications. The methods used include physical processes such as filtration, sedimentation, and distillation; biological processes such as slow sand filters or biologically active carbon; chemical processes such as flocculation and chlorination and the use of electromagnetic radiation such as ultraviolet light.
Purifying water may reduce the concentration of particulate matter including suspendedparticles, parasites, bacteria, algae, viruses, fungi, as well as reducing the concentration of a range of dissolved and particulate matter.
The standards for drinking water quality are typically set by governments or by international standards. These standards usually include minimum and maximum concentrations of contaminants, depending on the intended purpose of water use.
