Water purification systems are a necessity today considering the contamination and risks involved by unclean water sources. Water purification systems are most desirable as they ensure your family’s safe and good health. Undesirable contaminants, chemicals and materials are removed from the water by various processes making it fit for drinking and other purposes.
Water purification systems are designed for purposes that meet certain industrial, chemical, medical requirements. These techniques and methods include chemical processes like chlorination and flocculation, physical processes like filtration and sedimentation and also biological processes like slow sand filters and activated sludge. The use of ultraviolet light electromagnetic radiation is also used.
Water purification systems reduce the concentration of bacteria, algae, fungi, parasites and other suspended particulate matter in the water. Governments and International Standards set the standards as per maximum/minimum concentrations of contaminants allowed/required for various water purification systems. Pre-treatment of water is also done. Physical infrastructures using the right/appropriate materials should be constructed for containment of water so that there is no accidental contamination. Debris like fallen leaves, stones, sticks etc are removed by screening process that is done in the first steps of the purification process.
Pre-chlorination and pre-conditioning is done for water that is hard and has to be treated with soda ash/sodium carbonate, and to stop the growth of micro-organisms and bacteria both on the pipes and in the tanks. According to the quality of water being treated, the cost of a particular water purification process and the desired quality standards, methods and techniques of water purification are used.
Water purification systems that have advanced technology to produce clean, safe and pure water is important. These systems will ensure pure water from your kitchen faucet. The water purification system should have filtration and purification process by using ultra-violet lamp that is inbuilt and sterilizes the water destroying microbes, viruses and harmful bacteria.
It is necessary to have a water purification system that will give you pure water when and where you need it – whether you are out camping in the wild or at home. This way your family’s health and safety are always a priority. Water purity and quality is automatically monitored at all times.
Water purification systems should be designed to destroy all chemicals that are unwanted and water purification should be done without the addition of chemicals like silver, iodine, ozone, chlorine etc. The system should have user-friendly features that all can use. Compact units are available that fit inside the refrigerator and others are operated by solar energy thus making them eco-friendly and you an “environmentalist” if you install one.
Some water purification systems work on the “reverse osmosis” principle. This is also known as “hyper- filtration” process which is one of the most efficient. Glycol and ethanol are also purified by reverse osmosis. The process removes tiny particles from the water and also stops contamination in any form.
Water purification systems that use reverse osmosis process use a mechanical process that does not need a power source. The only drawback being wastage of two gallons tap water for each gallon of water filtered. A handy do-it-yourselfer can install a reverse osmosis filter easily.
