What is the process of STP plant?
Primary treatment In a sewage treatment plant, sewage water is first allowed to pass through screens or grit chamber where large solids are removed. This step is followed by aeration/mixing in a tank and then primary sedimentation where suspended solids settle down.
Why is activated carbon added to sewage?
It get on to absorb all the organic molecules associated with the smell and distinct colour. In many design the activated carbon sets are filled just after the settling chamber; thus allowing waste water to be treated before moved to next chamber.
What is sewage treatment plant?
A sewage treatment plant is designed to treat and process raw sewage over different steps involving breaking, filtering, settling, controlled aerobic decomposition and chemical treatment. One of the most common things that come in our mind regarding human waste; is to dump it to the sewers and let the government take care of it.
How long does it take for chlorine to kill bacteria?
This is done by adding a 5 % solution of chlorine to kill of bacteria within a period of 30 minutes. Further chemical treatment is done to remove the smell and get rid of the pale colour. The treated water is then either discharged to the sea, to shore facilities or used in toilets for flushing.
Where is raw water stored?
The raw waste water originating from toilet, wash basins and bathrooms; with a concentration of 0.1% solid waste by weight is stored in the primary chamber. The sewage is fed into the chamber with special macerator pumps that reduce human waste to slurry using blending and grinding techniques.
Does sewage smell?
So yes all sewage treatment plant smell but the smell produced is contained within its wall; to ensure convenience and safety of the operating crew in the engine room. But in case you be require to open the manhole above the screen filter; be prepared for the sudden burst of foul smell.

The preliminary chamber is equipped with coarse and fine mesh of screen as filters to remove large solid particles from getting into the system. In many designs it stay set at the top of the primary chamber with flow measurement device recording and filtering waste water inlet at the same time.
How does activated carbon work?
In many design the activated carbon sets are filled just after the settling chamber; thus allowing waste water to be treated before moved to next chamber. This is achieved by the process called adsorption. Many a times they not just used to remove odor and color; but also unwanted bi-product of biological treatment.
Why is sewage treatment important?
The importance of sewage treatment plant design is to withhold all the solids as much as possible and before the leaving water called an effluent is discharged to the environment. The solid matter decays it uses oxygen that are needed by the water plants and animals.
What is secondary wastewater treatment?
When the wastewater comes to the secondary phase the Effluents are treated further to remove dissolve suspended biological matter. The secondary treatment uses sedimentation and biological sludge. This treatment requires a separation process to remove the micro-organisms to then release it to tertiary stage of treatment.

Can sewage be reused?
With the ongoing water scarcity in cities and towns the only way ahead to treat the sewage water by sewage treatment plant so that the non-hazardous water can be reused to increase the surface water or recharge the ground table water.
What is tertiary treatment?
Tertiary treatment. In the last and final stage the water goes to filters again to remove more waste if any found lingering from the secondary treatment. The wastewater then is disinfected chemically either through micro-filtration which filters the water completely before releasing it to the seawater, lakes or ponds.
Why is sewage treated?
Sewage treatment is a process that is followed for the purification of used water that is often rich in contaminants. The treatment process is followed so that treated wastewater can be safely returned to the water cycle as environmentally friendly effluent.
What is a sewage water treatment plant?

Collection and treatment of sewage, along with purifying and returning the water to the environment in safe and environmentally friendly manner, is a keystone to adhering to the environment agency regulations and to protecting public health.
The working principle of a sewage treatment plant
Sewage treatment works by employing numerous physical, chemical, and biological treatment processes. A typical sewage treatment plant, in most cases, will first employ preliminary treatment involving screens and/or grit chambers to remove larger and heavier, often inert organic matter.
How does sewage get to the treatment plant?
The sewage enters the plants either via gravity (used water is flowing directly to the treatment plant), or under pressure/pumping (wastewater is collected in a chamber and a pump is to direct the wastewater to the tank).
Drainage fields for sewage treatment plants
Water after treatment can be discharged either on a surface water body or in the ground via drainage fields. Drainage fields are an important part of the process, especially for compact sewage treatment plants. A drainage field allows infiltration of the often partially treated effluent into the ground at a controlled rate.
