Drinking water could
become contaminated from breaks in pipes
that allow contaminants to intrude, intentional tampering, or loss of electrical power and pressure resulting in water stagnation and bacterial growth.
Can treated wastewater be used for drinking?
The process of using treated wastewater for drinking water is called
potable water reuse
. Potable water reuse provides another option for expanding a region’s water resource portfolio.
What are the main objectives of wastewater and drinking water treatment?
The major aim of wastewater treatment is
to remove as much of the suspended solids as possible before the remaining water, called effluent
, is discharged back to the environment. As solid material decays, it uses up oxygen, which is needed by the plants and animals living in the water.
What is the primary treatment of wastewater?
Primary treatment
removes material that will either float or readily settle out by gravity
. It includes the physical processes of screening, comminution, grit removal, and sedimentation. Screens are made of long, closely spaced, narrow metal bars.
What is the importance of water treatment?
To
live a long, active, and disease-free life
, installing a water treatment system is crucial. These systems are an investment that shields you from harmful waterborne pathogens and diseases and ensures your wellbeing.
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. Let’s examine these steps in more detail.
What are the three main stages of water treatment?
There are three main stages of the wastewater treatment process, aptly known as
primary, secondary and tertiary water treatment
. In some applications, more advanced treatment is required, known as quaternary water treatment.
What are the 3 stages of water treatment?

What is the process of water treatment?
They typically consist of several steps in the treatment process. 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.
What is the importance of water treatment plant for any city?
The water treatment plant engaged
for purifying water and making it suitable for human consumption ensures to prevent any short-term or long-term health risks for adverse impacts of the polluted water
.
What are the water treatment methods?
- Coagulation / Flocculation. Coagulation is adding liquid aluminum sulfate or alum and/or polymer to raw or untreated water. …
- Sedimentation. When water and flocs undergo the treatment process, they go into sedimentation basins. …
- Filtration. …
- Disinfection. …
- Sludge Drying. …
- Fluoridation. …
- pH Correction.
What materials Cannot be removed from wastewater?
When wastewater arrives at the treatment plant, it contains many solids that cannot be removed by the wastewater treatment process. This can include
rags, paper, wood, food particles, egg shells, plastic, and even toys and money
.
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 is new in water treatment technology?
Australian scientists have created a new water filter that renders highly polluted seawater drinkable after just one pass. The new invention utilizes a type of
graphene called Graphair
and may aid in providing safe drinking water to areas with limited access.
What are the 2 main steps used to treat water from lakes?
- Coagulation and Flocculation. Coagulation and flocculation are often the first steps in water treatment. …
- Sedimentation. During sedimentation, floc settles to the bottom of the water supply, due to its weight. …
- Filtration. …
- Disinfection.
What process produces pure water?
Distillation
. Distilled water is produced by a process of distillation. Distillation involves boiling the water and then condensing the vapor into a clean container, leaving solid contaminants behind. Distillation produces very pure water.
