Which is an effect of chlorine in water?
When chlorine enters the body as a result of breathing, swallowing, or skin contact, it reacts with water to produce acids. The acids are corrosive and damage cells in the body on contact.

What is the process of cleaning water called?
Water purification, process by which undesired chemical compounds, organic and inorganic materials, and biological contaminants are removed from water. … The purification procedure reduces the concentration of contaminants such as suspended particles, parasites, bacteria, algae, viruses, and fungi.
How do you purify drinking water?
Boil water, if you do not have bottled water. Boiling is sufficient to kill pathogenic bacteria, viruses and protozoa (WHO, 2015). If water is cloudy, let it settle and filter it through a clean cloth, paperboiling water towel, or coffee filter. Bring water to a rolling boil for at least one minute.
What is the best way to drink water at home?

Why does water need to be treated?
The aim of water treatment is to remove contaminants or reduce them to a concentration that means the water is safe to drink. … Contaminants include sediments and pathogens (bacteria, viruses, protozoa, larger organisms (worms) or salts and toxins (fertilisers, heavy metals).
What are the 3 stages of water treatment?
There are three main stages of the wastewater treatment process, aptly known as primary, secondary and tertiary water treatment.
What Cannot be removed from water?
Certain pesticides, volatile solvents, and volatile organic compounds (VOCs), such as benzene and toluene, with boiling points close to or below that of water will vaporize along with the water as it is boiled in the distiller.
What is process water used for?
Process water is water that is used for a variety of manufacturing processes, including: boiler make-up water; cooling tower make-up water; coating and plating; rinsing and spraying; washing and many others.
What are the 5 stages of water treatment?
These include: (1) Collection ; (2) Screening and Straining ; (3) Chemical Addition ; (4) Coagulation and Flocculation ; (5) Sedimentation and Clarification ; (6) Filtration ; (7) Disinfection ; (8) Storage ; (9) and finally Distribution.
How is water treated?
The 5 major unit processes include chemical coagulation, flocculation, sedimentation, filtration, and disinfection (described below). There are chemicals added to the water as it enters the various treatment processes.
What is the first step of raw water treatment?
Coagulation and flocculation are often the first steps in water treatment. Chemicals with a positive charge are added to the water. The positive charge of these chemicals neutralizes the negative charge of dirt and other dissolved particles in the water.
What is the most important step in water treatment?
It is, however, an important primary step in the water treatment process, because coagulation removes many of the particles, such as dissolved organic carbon, that make water difficult to disinfect. Because coagulation removes some of the dissolved substances, less chlorine must be added to disinfect the water.
What happens to water we drink?
The water we drink is absorbed by the intestines, and circulated throughout the body in the form of body fluids such as blood. These perform various functions that keep us alive. They deliver oxygen and nutrients to the cells, and take away waste materials, which are then eliminated with urination.
How many stages of water purification are there?
There are three practical and inexpensive choices when it comes to water filtration systems; Sediment and Carbon (2-stage), Reverse Osmosis (3-stage RO) and Reverse Osmosis/Deionization (4-stage RODI).
