Water Treatment Plants (WTP) generally are smaller operations than Wastewater Treatment Plants WWTP) because of the water quality coming in. WTPs pull water from a local river, lake or well. This water is generally clean (compared to sewage!) and just need a bit of cleaning and disinfection.
Is sewage treatment the same as wastewater treatment?
While there are similarities, sewage treatment is a part of the wastewater treatment process. It’s handled differently. To understand the differences, it helps to understand precisely what wastewater is.
Why is a sewage treatment plant better than a septic tank?
A sewage treatment plant is better than a septic tank because it actively treats the incoming sewage by aerating [adding oxygen to] the wastewater, either by a small air blower, or naturally via ventilation. The extra oxygen accelerates the natural biological process of breaking down the waste in the sewage.
What is the wastewater treatment process?
The overall wastewater treatment process has to clean the water of chemicals, food particles, and grit. It also has to remove human waste, which is where sewage treatment comes in. Wastewater is made up of black water and gray water.
What is the difference between water and wastewater?
Wastewater is mostly water by weight. Other materials make up only a small portion of wastewater, but can be present in large enough quantities to endanger public health and the environment.
Is there a difference between sewage and wastewater?
Sewage contains many of the elements present in wastewater, plus human waste. While both wastewater and sewage typically require treatment, non-residential wastewater types tend to require different treatment steps than those needed for sewage.
What is the difference between wastewater treatment and water treatment?
Water treatment is done to water before it is sent to a community, while wastewater treatment is done to water that has been used by the community. Water treatment has higher standards for pollution control because it is assumed that any drop of distributed water could be consumed by a person.
What are the 3 types of sewage treatment?
There are three main stages of the wastewater treatment process, aptly known as primary, secondary and tertiary water treatment.
What do you mean by wastewater treatment?
Wastewater treatment is the process of converting wastewater into water that can be discharged back into the environment. According to the U.S. EPA, one of the most common forms of pollution control in the U.S. is wastewater treatment.
Why is extra treatment required for industrial wastewater?
For this reason, extra treatment steps are often required to remove inorganic materials from industrial wastewater sources . For example, heavy metals which are discharged with many types of industrial wastewaters, are difficult to remove by conventional treatment methods.
What is sewage in a toilet?
There are two types of sewage: blackwater, or wastewater from toilets, and graywater, which is wastewater from all domestic sources except toilets. Blackwater and graywater have different characteristics, but both contain pollutants and disease-causing agents that require treatment.
Why is Oxymem used in wastewater treatment?
Because OxyMem uses gas permeable membranes, this allows oxygen to be transferred directly to the wastewater treating micro-organisms. Therefore, it is possible to deliver the oxygen required to maintain the populations in a much more cost effective manner.
Why is there an excess of nutrients in wastewater?
In severe cases, excessive nutrients in receiving waters cause algae and other plants to grow quickly depleting oxygen in the water.
What are some examples of wastewater?
Dairy plants and breweries are perfect examples of this. To combat any issues these types of wastewater sources tend to provide their own treatment or preliminary treatment to protect the main wastewater treatment system.
What diseases can be caused by wastewater?
Other important wastewater-related diseases include hepatitis A, typhoid, polio, cholera, and dysentery.
Is stormwater treated separately?
For example, to prevent flooding of treatment plants during bad weather, stormwater should be collected separately. Screens often remove rubbish and other large solids from storm sewers. In addition, many industries produce ...
What is Wastewater?

What is Sewage?
Sewage is, in essence, a subset of wastewater and includes business and industry waste, known as liquid waste. Sewage is the wastewater that generally comes from your toilet and laundry, and generally contains urine, faeces and laundry waste. Amazingly, a 4 person household generally produces around 400-500 litres of sewage a day!
Can you use the words wastewater and sewage interchangeably?
Not really.
Treatment Plants for Water
Basically, there are three types of treatment plants for water – water treatment plant (WTP), effluent treatment plant (ETP), and sewage treatment plant (STP). All of them have the sole purpose of treating wastewater.
Effluent Treatment Plant (ETP)
Effluent is wastewater coming from industrial and factory output. It contains harmful chemicals, toxic and non-toxic material in it.
Sewage Treatment Plant (STP)
Sewage is the wastewater coming from household, domestic and commercial outputs. They contain excreta of humans, animals, rainwater, debris from sewers in them.
Water Treatment Plant (WTP)
In simpler terms, consider a water filter in your home kitchen. The water coming inside the filter can be raw, from a bore well or normal contaminated one in small quantities.
What is the difference between wastewater and effluent?
Sewage contains excreta of humans, animals, etc, whereas effluent is wastewater that comes from factories or industries .
What industries use effluent plants?
3- Pharmaceuticals, chemicals, and leather industries generally make use of Effluent Plants where Sewage plants are utilized in residential areas like societies and apartments. For Any Product Enquiry Please Free to call Netsol Water Solution on - 9650608473 or email us - [email protected].
What is an ETP system?
1- ETP may be a system that removes toxic and non-toxic material from water and making it usable for various purposes . STP unit removes contaminants from municipal wastewater or household sewage.
Is water a jug?
Treating water from harmful toxins and chemicals is extremely essential. the world is majorly covered in water, but if we suppose that each one the water on its surface is collected during a jug, then the consumable water will only account for one spoon. The tremendous usage of water has caused an acute shortage of it in some places.
How does a septic tank work?
A septic tank can form the basis of a sewage treatment plant by acting as the chamber which facilitates primary treatment [settlement of solids] . After primary treatment, the effluent must flow to a second chamber for aeration, also known as secondary treatment [or biological treatment] to be considered a sewage treatment plant.
Why do you need a septic tank?
The primary reason you purchase a sewage treatment plant or septic tank is to receive and treat the sewage and wastewater from your dwelling. A septic tank is basically just an empty tank to store sludge. The only form of treatment that occurs is basic settlement of large solids.
What is low quality septic?
Low quality septic tank effluent means pollution of groundwater, pollution of streams and clogging of soakaways with effluent with very high amounts of suspended solids. So to protect the environment, to protect your drinking water and to keep your soakaway working well – a sewage treatment plant is a must have.
