BACKGROUND OF THE INVENTION
[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] One may neglect hunger for once, but one can’t imagine a day without water; such that wherever one goes, water is carried or is made available. Public spaces may offer water dispensers or taps to quench the thirst of any passersby. Unlike urban settlements, most rural communities rely directly on water bodies for sourcing their everyday water. All sources of water available in our surroundings may not be pure. Heavy metals, pesticides, bacteria, and dust are only some of the contaminants of water. Pathogenic microorganisms in water can cause a range of diseases including cholera, dysentery, and typhoid. Cholera caused by a gram-negative bacteria Vibrio cholerae has seen several outbreaks since 1918. Diarrhea is the third most common cause of death among kids under five in India. Thus, drinking water purification is an absolute essential to maintain a healthy and disease free body.
[0004] Water purification or treatment has existed since ages. Early humans used alum for precipitation which reduces the amounts of phosphorus in water. Boiling water is also a commonly used water treatment measure used in households. However it is not efficient in eliminating all forms of contaminants and is restricted to availability of a means for heating. Most of the water received in houses is treated at water treatment plants involving disinfection, coagulation, flocculation, sedimentation etc. However, despite these treatments one cannot be sure of the quality of water received. It depends on several local factors like the availability of water, industrial set up, wastewater treatment plans, efficiency of local administration and municipal authorities. Thus, there is a need for easy-to-use and efficient purification means that can be used by an individual anywhere to purify water before consumption.
[0005] Inventors of the present disclosure have come up with a portable water purifier that is employable at the point-of-use to provide clean and pure water for drinking.
