How is Municipal Wastewater Treated?
There are a few stages to the municipal wastewater treatment system as outlined below.
1. Background
Municipal water is known to many people as tap water. Around the world, water is supplied to industries and households through the use of a large number of underground pipes. Considering the complexity of underground pipes and the hidden problems of raw water quality, water quality cannot be guaranteed if it is delivered directly through pipes.
2. RO Desalination Technology for Municipal Water Supply Treatment
The traditional municipal water supply treatment equipment is relatively old, and the treatment process is backward, resulting in that the water still contains many granular impurities or pathogenic microorganisms with small particle sizes, which can not ensure people’s water safety.
3. Biological Oxidation Tower RO Technology for Municipal Sewage Treatment
With the increasing shortage of water resources and the aggravation of water pollution, measures such as water-saving and inter-basin water transfer can not fundamentally solve the crisis of urban water shortage. Municipal sewage is a potential water resource with stable water volume and reliable supply.
4. Portable Reverse Osmosis Drinking Water Device
Due to objective factors such as pipeline transportation length, the municipal water supply treated by reverse osmosis can not be directly drunk after being transported to residential areas or public places. There are also trace microorganisms and bacteria in the water. Direct drinking will have a negative impact on people’s bodies.
Coagulation
One of the first stages in the municipal water treatment system is coagulation. A chemical with a positive electrical charge, like alum, is essential for this step. This chemical, known as a coagulant, neutralizes the negative charges that water contaminants have.
Flocculation
Once the coagulant goes into the water, the water is slowly mixed. Mixing encourages the coagulant to spread evenly in the water. The coagulant clumps neutralized contaminant particles together in larger clusters, known as floc.
Sedimentation
The mixture of water and floc goes to a sedimentation tank, also known as a clarifier, to remove the floc from the water. The floc is heavier than the water, allowing it to settle to the bottom of the tank because of gravity. The particles at the bottom of the tank are known as sediment and can now be removed.
Filtration
After removing the sediment from the water, the water goes through a series of filters. Different materials, such as charcoal, sand, and gravel, make up these filters. The materials in the filters are of various sizes, so the size of the spaces between them, known as pores, are different as well.
Disinfection
Ultraviolet light or a disinfectant such as chlorine treats the filtered water. Disinfection also kills microbes such as bacteria or viruses. After this step, the water should be safe to drink since most of the contaminants that were in the water should be gone.
Fluoridation
Many municipalities, especially in North America, add fluoride to drinking water to prevent tooth decay. The fluoride makes tooth enamel stronger.
Storage and Distribution
The water is now clean enough to drink and goes to storage tanks before consumers use it. Distribution systems consist of storage tanks, pipes, and pumps that help get the water to nearby communities.
What are trace contaminants?
Trace contaminants are elements, complexes, and compounds that are both human-made and/or naturally occurring in water (at very low levels) and must be removed from drinking water or wastewater for health or regulatory reasons.
What are the water sources of municipal communities?
Water sources for municipal localities vary from ground water to lakes and rivers — even the sea itself. Few water sources remain pristine enough to be consumed without some form of treatment, however. Innovation plays a major role in ensuring a clean, safe, and affordable supply of water.
Is municipal water treatment safe?

How does flocculation work?
Coagulation and flocculation work by clumping particles and solids together by introducing chemicals like aluminum sulfate or iron that cause all contaminants to give off a positive charge . Coagulated particles are easier to filter out through settling water treatment or by sticking to sand or rock.
What is tertiary disinfection?
Tertiary Treatment. Water treatment disinfection is the last stage in the treatment of municipal water and is vital for the removal of pathogens. Most municipal water systems have a requirement to maintain a level of disinfection in the supply for a certain number of days before it reaches the consumer. Wastewater chlorination is the most common ...
What is secondary treatment?
Secondary Treatment. Several techniques can be used to filter and dissolve solids during the secondary treatment phase. The municipal water treatment methods used will depend on whether this is a hard-water area, cost, and any quality requirements that need to be in place.
What is pH adjustment?
pH adjustment is applied where the water supply is acidic. In this situation lime or soda ash is added to raise the pH level. When water is slightly alkaline it enables flocculation and coagulation to work more effectively during the municipal water treatment process.
What is the difference between primary and secondary treatment?
The main difference between the primary and secondary treatment of wastewater is that primary relies mostly on physical cleaning, while secondary treatment introduces chemical procedures and microorganisms. In the final stage, or tertiary treatment, at the municipal water plant, pH adjustment, disinfection, and carbon treatments are applied.
What is the process of treating water with calcium carbonate?
In hard-water areas, water is treated with sodium carbonate to precipitate calcium carbonate, a process known as pre-conditioning. Finally, this primary treatment phase ends with pre-chlorination where water coming into the plant is chlorinated as part of the disinfection process.
How many processes are there in municipal water treatment?
