What are the different types of sewage?
There are three types of wastewater, or sewage: domestic sewage, industrial sewage, and storm sewage. Domestic sewage carries used water from houses and apartments; it is also called sanitary sewage. Industrial sewage is used water from manufacturing or chemical processes.

Sewage goes through several stages in the treatment process ensuring that all harmful bacteria, pollutants and contaminants are eliminated.Jun 5, 2017
What is treatment of sewage and its classification?
Sewage treatment (or domestic wastewater treatment, municipal wastewater treatment) is a type of wastewater treatment which aims to remove contaminants from sewage to produce an effluent that is suitable for discharge to the surrounding environment or an intended reuse application, thereby preventing water pollution ...
What are the different types of sewers?
The three types of sewers are sanitary sewers, storm sewers, and combined sewers.
How does a combined sewer system work?
How combined sewers work is by collecting all the water from rain and snow into a pipe and then adding human waste into the same pipe. In ideal circumstances, this system would pump these combined wastes to a treatment plant where it would then return safely to the environment.
Why is a sanitary sewer system important?
The main purpose of a sanitary sewer is to carry waste away from homes and businesses to wastewater treatment plants.
How does sanitary sewer work?
How these sanitary sewage systems work is by carrying human waste through small plumbing pipes in the home, to gradually bigger pipes outside, until it reaches the main sewer line in the street. From here the sewage is transported to a wastewater treatment plant to be treated and returned safely to the environment.
What are the different types of sewer systems?
There are three types of modern sewer systems: Sanitary sewers (also called foul sewers), storm sewers ( also called surface water sewers), and combined sewers. In this brief article we’ll go over the basics of each….
Why are combined sewers not used anymore?
They aren’t used much anymore because when it rains a lot the system can’t handle both the surface water and the wastewater and this causes the sewer to overflow.
How do sanitary sewers work?
Usually, sanitary sewers use gravity to carry the wastewater away. However, in low-lying areas pumps are sometimes used when the wastewater needs to reach an area that’s at a higher elevation. Sanitary sewers are accessed via manholes for routine maintenance and repair.
What is the role of a sewer?
They consist of pipes, manholes, and pumping stations and their role is to maintain water quality because it’s necessary for good public health. Here’s how they work….
What Is A Sewage Treatment Plant?
Sewage treatment is all about polluted water. These are created in different types of industries, and this water contains harmful chemicals that are harmful to living beings. Sewage treatment plants are used to treat the sewage into a usable form.
What Are The Different Types Of Sewage Treatment Plants?
Sewage treatment for residential or commercial buildings requires different processes depending on the size and type of building. One way to make this determination is by the amount of water that flows through each day (gallons per day), determining what kind of equipment is needed.
Conclusion
Sewage Treatment Plants have become a vital sector in the waste management industry. This is the primary reason for new environmental threats from pollutants and hazardous wastes.
What are the different types of sewer systems?
The sewerage systems or water carriage systems are of the following three types: 1. Separate System 2. Combined System 3. Partially Separate System. Type # 1. Separate System: In this system two sets of sewers are provided-one for carrying domestic or sanitary sewage and industrial sewage, and the other for carrying storm water (or rain water). ...
What is combined sewer system?
Combined System: In this system only one set of sewers is provided for carrying domestic or sanitary sewage and industrial sewage as well as storm water (or rain water). Thus in this case sewage and storm water (or rain water) are carried to the sewage treatment plant before its final disposal.
Why do large sewers get silted up?
Moreover, the dry weather flow being a small amount of the total flow, the large size sewer would often get silted up due to low velocity of flow during the dry part of the year. (viii) Large sewers are more difficult to be ventilated than the smaller ones.
What is the aforesaid discussion about sewerage?
The aforesaid discussion indicates that there are several factors which govern the choice of the sewerage system. Thus each type of sewerage system to be adopted should be carefully studied keeping in view the various factors before a final choice of the system is made.
Why do you need separate sewers?
In such cases separate sewers are more economical, because laying of a combined sewer of larger size at a greater depth below the ground surface will be costly.
How long does sewage flow during monsoon?
(i) Heavy and concentrated rainfall occurs during the monsoon period, which at most places lasts for only 3 to 4 months in a year. Thus there is a large variation in the quantity of sewage flowing during the different months of the year.
Where does sewage go from the first set of sewers?
The sewage from the first set of sewers is carried to the treatment plant, and the storm water (or rain water) from the second set of sewers is directly discharged into a natural stream or river without any treatment. ADVERTISEMENTS:
What is wastewater treatment
Treatment of wastewater is a major step in preventing the pollution of our freshwater resources. The process uses specialized machines to remove pollutants such as metals, debris, microorganisms, and biowaste from the water before it is returned to its source, be it surface water or groundwater.
There are four types of wastewater treatments
This treatment method involves the following steps: infiltration, grit removal, primary sedimentation tank, secondary sedimentation tank, and secondary clarification. This process is used to treat domestic wastewater and commercial waste.
Stages of wastewater treatment
Wastewater treatment is the process of cleaning wastewater before it is discharged back into waterways or utilized as a reclaimed water source. Here are the three stages that help us achieve that.
Sewage treatment
There are different types of sewage treatment plant available. Sewage treatment is the method of removing pollutants from wastewater, mostly from household sewage. Moreover, to extract these pollutants and produce environmentally healthy treated wastewater, it uses physical, chemical, and biological processes (or treated effluent).
More on STP
Effluent usually discharge with a BOD concentration equal to the appropriate minimum, but it may also be diluting to the lower levels. The discharge concentration times the flow volume equals the total mass of BOD discharged to receiving waters.
Types of Sewage Treatment Plants
Wastewater Processes: Sewage treatment plants come in a variety of shapes and sizes, each with its own treatment procedure.
What are activated sludge plants?
The activated sludge process uses bacteria (to dissolve biodegradable organics) and air to treat sewage and wastewater, which is widely referring to as effluent (Oxygen for respiration). A mixture of microorganisms and suspended solids are referring to as activated sludge.
What are Rotating disc system?
It is a biological treatment method that we uses after primary treatment to treat wastewater. A screening phase followed by a cycle of settlement eliminates the grit and other solids in the primary treatment process. Allowing wastewater to enter a biological medium is a part of the RBC procedure.
Bottom Line
Contaminants are removed from wastewater at sewage treatment plants. This plant will produce untreated waste from residential and industrial buildings and commercial wastewater on occasion. This form of STP is critical in keeping people safe and secure by cleaning their wastewater.
