What Is Sewage Treatment Plant How It Works?
A sewage treatment facility is in charge of cleaning wastewater thoroughly and removing toxins before it is released back into the environment. It is undeniable that without sewage treatment methods, animals would become ill or die, beaches, dunes, and salt marshes would become unsuitable for both humans and animals, and water would quickly become contaminated and dangerous to drink or use.
How does sewage treatment plant work?
Bar Screen
The Bar Screen's job is to screen out any potential particles that could clog the pipes inside the STP in order to avoid blockages from occurring.
After a few weeks, all of these particles are removed as part of STP maintenance.
An Equalization Tank
The main job of the equalization tank is to serve as a buffer. to position to the rest of the ETP at a stable (Average) flow rate and collect the incoming raw effluent that comes at highly variable rates. ETP is delivered at a high flow rate during peak hours with the aid of blowers. When there is no or very little incoming effluent during non-peak hours, the equalization tank stores this wastewater and releases it. Filtered effluent is carried in the equalization tank's inflow pipe to avoid clogging.
Aeration Tank
The Equalization Tank to Aeration Tank sewage is transferred using a sewage lifting pump.
Aeration is used as a pretreatment in the water treatment process to get rid of iron and hydrogen sulfide, which gives water a rotten egg odor. Iron and hydrogen sulfide are both effectively oxidized by air. It swiftly transforms ferrous iron that cannot be filtered into ferric iron that can be filtered, and it turns hydrogen sulfide to elemental sulfur, which can be readily removed from water by a filter. Air oxidizes substances very quickly—much more quickly than chlorine.
Tube settler tank.
Poly Aluminum Chloride (PAC) is transferred from the PAC tank into the Tube Settler Tank. PAC is a good coagulant with low sludge waste generation and high coagulant efficiency.
Tube settlers use numerous tubular channels that are close to one another and inclined at an inclination of 60 degrees to maximize the effective settling area. As a result, settling periods are shortened because the particle settling depth is substantially lower than that of a traditional clarifier.
The bigger floc is able to travel to the tank bottom in a more settleable state because tube settlers grab the settleable finefloc that escapes the clarifying zone beneath them. Solids are gathered in the tube settler's channel into a tight mass, which encourages the solids to slide down the tube channel.
Immediate storage tank
The chlorine dosing tank discharges chlorine into the nearby storage tank.
When chlorine is used to treat water, it helps to delay the activity of anaerobic sulfate-reducing substances and also helps to lessen odor-related annoyance. Also, while the germs are still in the immediate storage tank, chlorine aids in their destruction.
The Filter Feeds
The water is sent to the pressure sand filter by the filter feed pump.
Several layers of sand with different sizes and specific gravities make up the Pressure Sand Filter. These filters are made to remove turbidity and suspended particles from feed water with the least amount of pressure loss possible. After that, the water is sent to a carbon filter, which is the best at eliminating chlorine, sediment, volatile organic compounds (VOCs), taste, and odor from water. They are ineffective at eliminating dissolved inorganic chemicals, minerals, and salts (DOCs).
Treated Water Tank
Depending on where the sewage treatment plant is located, this is the water's eventual destination, where it will be dispersed for either home or industrial usage.
Final disposal typically involves the use of the material as fertilizer on fields, deposition at waste disposal facilities, or incineration either internally or with an external partner, frequently as part of the production of electricity.
