The goal of water purification is to remove contaminants and prepare it for a specific purpose. Most of it is prepared for human consumption but not all. Some may be prepared for pharmaceutical lab use or for industrial usage. There are numerous methods that can be used for these purposes. They can be used singularly or alone dependant on the source of the liquid.
The methods that are used include processes like filtration to remove large pieces of flotsam such as sticks or debris. These smaller particles settle to the bottom of the container while sitting idle waiting to be moved. This dropping of small particulates is helpful and can occur in only a few hours of inactivity.
There are other types of contaminates that need more intense treatment. Parasites, algae, fungi and viral diseases usually require treatment such as with chlorine. Further treatment may require radiation or an ultraviolet ray treatment. When it rains chemicals and biological materials are picked up from the soil and the liquids must be treated to remove them prior to use by anyone.
Scientists and politicians set the standards for human consumption. They usually have a minimum and maximum standard for particulate and chemical ingestion for any product and so long as the standards are met by distributors there are no problems. Only when there is a crisis and it can be proven do the standards change.
Boiling or filtering liquids in your kitchen is not a sure thing when it comes to contamination. In this case what you cannot see can hurt you. Unknown particulates are not removed by these methods. Even drinking from a natural spring is not a safe practice. There are too many chemicals that sink into the soil and end up in our drinking sources.
A World Health Organization (WHO) report from 2007 determined that over a billion people worldwide do not have access to clean drinking waters. There are four billion cases of diarrheal disease reported every year. Of these cases more than eighty eight percent can be attributed to contamination, unsanitary living conditions and personal hygiene.
It has been determined by the WHO that over ninety percent of these cases are preventable by modification of living conditions and clean drinking water. By providing the simplest techniques for purification to these populations millions of lives could be saved each year. Storage in safe containers along with chlorination, filtration and solar disinfection could provide healthy and clean drinks to those who live in affected areas at price the world can afford.
There are seven sources available for consumption by humanity. Most are available to all populations and can be treated for contamination and made potable. Whether it comes from the ground, a lake or a river it is a viable resource for consumption. Rain and fog can be collected in containers in less developed nations for use by people in refugee camps. Working towards the reduction of sickness and aiding the prevention of deaths caused by waterborne diseases needs to be a major goal of all nations on the planet. When working together as a planet water purification needs to be a priority one project.
