Save life: Please give me a little water, I am thirsty, hungry, ...


-Would you like to reduce the Processing cost of waterfrom 10 paise to 9 paise per liter

-Providing access to potable water has become a human right through various designations in international treaties and declarations. Water-related diseases remain the number one cause of death for children under five worldwide, these problems are particularly evident in rural areas of developing countries. In addition, emerging contaminants and disinfection by-products have been linked to chronic health problems for people in the developed and developing world. The World Health Organization estimates that 80 percent of all sickness in the world is attributable to unsafe water and sanitation. Water-borne diseases kill 3.4 million people, mostly children, annually. Millions more are sickened with diarrhea, malaria, schistosomiasis, arsenic poisoning, trachoma, and hepatitis-diseases that are preventable by access to clean water and health care information as shown here 

The provision of safe water alone will reduce diarrhoeal and enteric disease by up to 50%, even in the absence of improved sanitation or other hygiene measures.

Please keep in mind that chemical dyes are the complex molecular structures, which are widely used in many industries such as textiles, paint, leather and food processing. The acquittal of dyes from these industries into the aquatic environment has triggered many problems to the public health due to their toxic nature and carcinogenicity.


Specification: -Pollutant content in the purified water should be less than the critical limit suggested by the WHO standards or Indian Standards. -For example: pH-6.5-8.5, Hardness- 0-75, Mercury: 1.0 microgm/L, Iron: 0.3 mg/L, Arsenic: 10.0 microgm/L, Lead: 10.0 microgm/L, Fluoride: 1.5 mg/L, Pesticide (total): 0.50 microgm/L, Pathogen: (not mentioned), etc
