FAQ

Why the Quality of drinking water is deteriorating?
    Our water sources are increasingly getting polluted. As a result the water we get is full of impurities and not fit for drinking.
  • River water, which is our primary source of water, gets contaminated due to various reasons such as direct disposal of sewage by municipalities, excessive discharge of industrial pollutants, use for daily chores like washing, bathing, livestock bathing, garbage disposal, etc.
  • Water sourced from groundwater too has deteriorated due to the excessive use of pesticides & insecticides in agriculture, which seep into the groundwater as well as get washed away into the rivers. Decreasing levels of groundwater also attracts natural contaminants present in the earth such as Arsenic, Fluoride, Lead, Heavy Metals, which make the water hard.
  • Our municipalities are not well equipped to completely purify the water we drink. They are unable to remove harmful dissolved impurities as they use outdated methods of purification such as chlorination and filtration. The pipes in which the water is supplied are rusty which makes the municipal water polluted and the overhead tanks in which water is stored are breeding grounds for bacteria and viruses as they are seldom cleaned.
Why the Quality of drinking water is deteriorating?
      Impurities found in drinking water can be broadly classified into:

    a)Suspended impurities such as mud, dust, sand, bacteria, viruses, cysts, etc b)Dissolved impurities that become soluble in water such as-
  • Pesticides (commonly found in borewell water)
  • Arsenic & Fluoride (found in groundwell water)
  • Heavy Metals salts like mercury, lead, copper, cadmium (from industrial wastes)
Why it is essential to remove dissolved impurities from drinking water?
Dissolved Impurities such as Pesticides, Rust, Heavy Metals, Arsenic, Fluoride etc. are harmful to our health. They may cause serious diseases such as cholera, hepatitis A & B, jaundice, typhoid and even cancer. They also spoil the taste of water. When these dissolved impurities are removed, the water becomes healthy as well as tasty.
What types of technologies are available for purifying water?
The most commonly used methods of purification are Chlorination, Boiling, Ultra filtration (UF), Ultra Violet (UV) Disinfection and Reverse Osmosis (RO) Purification.
Why Boiling alone does not make water fully safe for drinking?
Boiling kills bacteria and viruses but does not remove harmful dissolved impurities such as Pesticides, Rust, Heavy Metals, Arsenic, Fluoride etc. Just as we cannot remove dissolved salts from water by boiling, similarly we cannot remove dissolved impurities from water by boiling.
Presence of such impurities in water may cause serious diseases such as cholera, hepatitis A & B, jaundice, typhoid and even cancer.
What are the disadvantages of purifiers using only UV technology?
UV purification has been popular since last few years. It does kill bacteria and viruses but does not remove dissolved impurities such as Pesticides, Rust, Heavy Metals, Arsenic, Fluoride etc. Also ‘khaara’ water does not become sweet.
