What is pH?

You may have heard the word “pH” used to describe drinking water quality, but do you know what it means?
.
pH is a measurement of electrically charged particles in a substance. It indicates how acidic or alkaline (basic) that substance is. The pH scale ranges from 0 to 14 :
•  Acidic water has a pH lower than 7. The most acidic substances have a pH of 0. Battery acid falls into this category.
•  Alkaline water has a pH of 8 or above. The most alkaline substances, such as lye, have a pH of 14.
•  Pure water has a pH of 7 and is considered “neutral” because it has neither acidic nor basic qualities.
What pH is safe for drinking water?
The U.S. Environmental Protection Agency (EPA) is in charge of monitoring public drinking water quality across the United States.
pH isn’t a quality that falls under EPA regulation because it’s considered an aesthetic quality of water. However, the agency recommends that municipal drinking water suppliers keep their water supply at a pH of 6.5 to 8.5.
What does a changing or unsafe pH mean?
Freshwater pH varies across the world depending on weather patterns, human activity, and natural processes.
Water with a very low or high pH can be a sign of chemical or heavy metal pollution.
Water that doesn’t fall in the “safe” pH range of 6.5 to 8.5, particularly if it’s alkaline, isn’t necessarily unsafe. However, very alkaline water can have an unpleasant smell or taste, and it can also damage pipes and water-carrying appliances.
Acidic water with a pH of less than 6.5 is more likely to be contaminated with pollutants, making it unsafe to drink. It can also corrode (dissolve) metal pipes.

The ideal pH level of drinking water should be between 6 – 8.5.

UV Light Sterillizer

What is UV Light Sterillizer? . The use of ultraviolet light (UV) for germicidal irradiation is not a new idea. UV has been used for disinfection since the mid-20th century, with beginnings even earlier when sunlight was investigated for bactericidal effects in the mid-19th century. It’s used for drinking and wastewater treatment. UV has been proven effective against a broad spectrum of microorganisms. Viruses contain RNA or DNA and are thus susceptible to irradiation. Bacteria and fungi both contain DNA and are similarly vulnerable to UV light. Spores are also susceptible to UV. . How Does UV Work?? . Ultraviolet light exists within the spectrum of light between 10 and 400 nm. The germicidal range of UV is within the 100-280nm wavelengths, known as UV-C, with the peak wavelength for germicidal activity being 265 nm. This range of UV light is absorbed by the DNA and RNA of microorganisms, which causes changes in the DNA and RNA structure, rendering the microorganisms incapable

Why Is Chlorinated Harmful ?

Why Is Chlorinated Harmful ? Chlorine has long been used to disinfect our drinking water because it controls the growth of such unwelcome bacteria as Ecoli and Giardia. Chlorine can enter the body through skin absorption or through the eyes, nose, and ears. What are the harmful effects of chlorine? Inhalation of chlorine gas or drinking highly concentrated sources of chlorine (such as household bleach) can lead to vomiting, coma, and even death. For this reason, many people fear that the chlorine in swimming pools and drinking water can be harmful for health, and cause cancer. Eye and skin irritation may be the problem issue. Why is chlorine in drinking water dangerous? Because when chlorine mixes with even minute amounts of organic compounds that are very often found in water, harmful by-products, called Trihalomethanes (THMs) are produced. These by-products produce free radicals in the body, which trigger cell damage — and are highly carcinogenic, even in small amounts. Chl
