Method and apparatus for liquid purification
a technology of liquid purification and liquid filtration, applied in the direction of multi-stage water/sewage treatment, water treatment parameter control, chemical/physical/physicochemical processes, etc., can solve the problems of purifying water, many contaminants percolating down through the soil and into the underlying water table in the world, and still reported cases

Benefits of technology
The apparatus effectively removes contaminants, microorganisms, and volatile organic compounds, providing high-purity water with a reliable UV light source and indicator for filter replacement, ensuring continuous safe water supply.
Problems solved by technology
The extensive use of fertilizers and pesticides by farmers, runoffs from major animal husbandry sites, contamination spills by industries, the dumping of raw sewage into our lakes and streams and the significant number of landfill sites have caused many contaminants to percolate down through the soil and into the underlying water tables throughout the world.
However, cases are still reported in the U.S. of contaminated water supply systems.
Carbon does reduce some toxic chemicals and gases from water however it does not purify the water.
This device is also greatly limited by the capacity of water that it can produce in a 24-hour period.
It most certainly would not produce enough filtered water to supply a family of four with enough drinking and cooking water for an entire day.
However, these systems do not address the issue of microorganisms in the water, which can bypass the filtration systems.
Unfortunately, the UV lamp deteriorates over time to the point that it cannot produce the necessary wavelength to kill microorganisms in the water.
Furthermore, the system does not provide a means to know when the UV lamp has deteriorated.
As such, the end user may think that the device is adequately killing microorganisms when in fact the UV lamp has become useless as a biocide.
This material is primarily used in large municipal water treating systems however there have been some attempts to have the KDF 85 or KDF 55 material impregnated onto a paper filter for point of use water treatment systems with limited success.
While all of the above presented means provide some degree for improving the water supply, none of them fully purify the water in an economical and efficient manner.

Abstract
An apparatus and method for purifying a liquid comprising a photolytic light chamber producing ultraviolet light in the 100 to 300 nanometer range, said light passing through a quartz tube or lens to irradiate the liquid passing through a chamber containing the liquid.
Description
[0001] This application is a division of application Ser. No. 10 / 9805039, filed on Dec. 13, 2004 in the name of the same inventor.BACKGROUND ON THE INVENTION [0002] Presently, the quality of the global pure drinking water supply is decreasing at a faster rate than the population is expanding. The United Nations International children's Educational Foundation (UNICEF) estimates that 20,000 to 30,000 children die every day from waterborne diseases such as typhoid, malaria, e-coli, cholera and many other contaminants. These contaminants can also include such things as salts, halogens, organic solvents, pesticides, fertilizers, industrial chemicals, bacteria, protozoa, fungi and other foreign matters. [0003] The extensive use of fertilizers and pesticides by farmers, runoffs from major animal husbandry sites, contamination spills by industries, the dumping of raw sewage into our lakes and streams and the significant number of landfill sites have caused many contaminants to percolate dow...
