Zero Cost Water Purification by L. E. D. Light and Copper Complex

Anil Kumar Gupta, Lokesh Saxena

Abstract


The white light reflects seven colors through prism. All of these colors of light are used in light emitting diode bulbs to produce light that appears white. However out of these colored lights, the orange and blue light may be well utilized for purification of contaminated household water. Purification of household contaminated drinking water by reverse osmosis gives clean water but with low T.D.S. Since household water is already chlorinated therefore this do not necessarily needs reverse osmosis which may cause osteoporosis and arthritis problem in the long run. Therefore a zero cost new technique of household drinking water was designed wherein light of different wavelengths is subjected through LED bulb into a copper vessel having water. The orange component of the light is absorbed by cupric ions to form hexa aqua copper (II) ion which kills the bacteria and the blue component of light kills the viruses. The ceramic filter candles fitted in the upper part of the copper vessel is able to maintain the T.D.S. between the ranges of 100 to 250. The noble features of this Zero cost Copper purifier over other known alternatives are mainly ; pH of the water is found to be 7.03 which is neutral but pH of the R.O. water was 6.54(slightly acidic); no plastic; no motor; nominal consumption of electricity; nominal price; optimum T.D.S.; portable and bactericidal. This purifier can now be afforded by every middle class household and poor. The system cut emissions according to conference of parties at Paris (2015) to tackle global warming because of less consumption of coal which is required to produce electricity.
