Sewage Treatment Plant

• Primary treatment consists of temporarily holding the sewage in a quiescent basin where heavy solids can settle to the bottom while oil, grease and lighter solids float to the surface. The settled and floating materials are removed and the remaining liquid may be discharged or subjected to secondary treatment. Some sewage treatment plants that are connected to a combined sewer system have a bypass arrangement after the primary treatment unit. This means that during very heavy rainfall events, the secondary and tertiary treatment systems can be bypassed to protect them from hydraulic overloading, and the mixture of sewage and stormwater only receives primary treatment.
• Secondary treatment removes dissolved and suspended biological matter. Secondary treatment is typically performed by indigenous, water-borne micro-organisms in a managed habitat. Secondary treatment may require a separation process to remove the micro-organisms from the treated water prior to discharge or tertiary treatment.
• Tertiary treatment is sometimes defined as anything more than primary and secondary treatment in order to allow ejection into a highly sensitive or fragile ecosystem (estuaries, low-flow rivers, coral reefs,...). Treated water is sometimes disinfected chemically or physically (for example, by lagoons and microfiltration) prior to discharge into a stream, river, bay, lagoon or wetland, or it can be used for the irrigation of a golf course, green way or park. If it is sufficiently clean, it can also be used for groundwater recharge or agricultural purposes.

A sewage treatment plant is an industrial facility for the treatment of urban wastewater, largely from toilets and bathrooms, to produce a non-polluting effluent that can be used as part of another process or directly discharged into the environment (for example, rivers). They may also be known as "wastewater treatment works" or "wastewater treatment facilities", treated water as well as sludge are recycled. A WWTP is designed in accordance with the waste composition of the metropolitan area served.

In a sewage treatment plant, they treat the waste before it's discharged into the ocean.

The sewage treatment plant is divided into primary and secondary treatment stages. The primary stage takes place in the screening and grit removal system, where large solids are removed by grit chambers. The secondary stage takes place in several types of settlement tanks, where the activated sludge process is used to remove the organic matter from the wastewater. Treated effluent can then be discharged directly to surface water or further treated for reuse (biogas facilities for gas production or for irrigation as fertiliser, aquaculture facilities).

The sewage treatment plant is a handling plant for separating and reducing the polluting load of untreated municipal sewage brought into it by sewers. The main treatment process consists of sedimentation, where suspended matter falls to the bottom, followed by clarification and filtration. After treatment, the cleaned water, called effluent or secondary waste water, is discharged, either into streams via surface drains or into artificial bodies of water like lakes or reservoirs.

• Pre – Treatment Screening : This is the first units of the plant in which large or floating materials in the sewage gets arrested and blockage or choking of the downstream equipments can be avoided. This arrested material will be removed manually and then will be disposed off suitably Equalization : To absorb variation in quantity and quality of sewage and to provide uniform flow at the downstream treatment process, a collection or equalization tank is provided. This will avoid shock loading and process upsets of the treatment plant. To avoid settling of suspended solids in this tank continues air agitation is provided. If at site, septic tank is provided then collection tank as well as air agitation is not required.
• Biological Treatment : This is the main section of the plant where degradation of organic pollutants with the help of aerobic micro-organism takes place. To provide higher surface area for micro-organism, floating media is provided. On which micro-organism growth takes place. This makes bioreactor is of hybrid concept in which both suspended growth as well as attached growth principal for micro-organism is achieved. Due to higher population of micro-organism, effective volume of bioreactor reduced drastically as compared to conventional aeration tanks. To maintain the aerobic condition in the bioreactor, air supply arrangement is provided by means of aeration equipment which has high oxygen transfer efficiency Tube Settler : Gravity overflow from the bioreactor is collected in the tube settler tank. In this settling tank, generated sludge from the bioreactor undergoes a gravity settling. Clear supernatant from settling tank will flow by gravity to a chlorine contact tank. To reduce the plan area of settling tank, tube modules are placed in this tank to increase the settling area of the tank. Since this tank is a hopper bottom tank due to which there is no need of sludge scrapping mechanisms.
  
• Disinfection : Supernatant from Tube settler, flow by gravity to the chlorine contact tank. To disinfect the harmful bacteria in the treated water as well as to remove the refractory organics from treated water, in this tank hypo chlorite solution is dosed with the help of dosing system. Sludge Handling System : Generated sludge from clarifier/tube settler is pumped to either sludge holding tank or any sludge dewatering equipment
• Tertiary treatment : Secondary treated water will be further passed through pressure sand filter followed by activated carbon filter. Filtered water will be collected in the Treated water Storage tank from where it will be for desired non potable application. Backwashed water from filters will return back to equalization tank.

Description:

• Untreated sewage if discharged in to river or water bodies pollutes these fresh water bodies due to its organic contents.
• If it is allowed to soak in to the soak pits then over a period of time surrounding underground water bodies such as bore wells, wells etc gets polluted.
• Harmful pathogens & microbes present in the human excreta gives birth to various epidemic diseases.
• To avoid this & to have hygienic living conditions, it is must to treat the sewage before discharging out from the complex or establishment.

Packaged sewage treatment plant is mainly used for the biochemical treatment of domestic sewage from urban and rural households, hotels, restaurants, schools, municipal departments and military enterprises. The treated effluent standard is generally A-Class (inland) at B-Class (coastal)
