Sewage Treatment Plant -
A sewage Treatment Plant is a machinery process to treat the waste and wastewater generated from households, offices, restaurants, hotels, factories, municipalities, corporations, and so on. In other words, Sewage treatment plants are generally used for the treatment of wastewater in order that they are often made fit use within the fulfillment of different purposes, even the wastewater beginning of varied manufacturing and supplying units isn’t fit to be released within the environment or within the water bodies.
Sewage is made up of wastewater from homes and businesses and perhaps pre-treated industrial waste. There are numerous sewage treatment processes from which to choose. Decentralized systems (including on-site treatment systems) to huge centralized systems incorporating a network of pipelines and pump stations (referred to as sewerage) that transport sewage to a treatment plant are examples. The sewers will also convey urban runoff (stormwater) to the sewage treatment facility in communities that have a combined sewer.
There have been numerous sewage treatment technologies created, the majority of which use biological treatment processes. When selecting an appropriate technology, engineers and decision makers must consider technical and economic criteria, as well as quantitative and qualitative characteristics of each option.
Sewage Treatment Process -
1. Preliminary Treatment: This is the first stage of the sewage treatment plant process and its main objective is the removal of coarse solids and other large materials often found in raw wastewater. Preliminary treatment operations typically include large filtering screens, grit removal, and, in some cases, the breaking of large objects. Excess grit causes severe pump blockages thereby affecting a range of subsequent treatment pumps.
2. Primary Treatment: The main purpose of this treatment is to reduce any heavy solids (organic & inorganic) that settle to the bottom by sedimentation while oil, grease & lighter solids float to the surface by skimming. The settled and floating materials are removed and the remaining liquid may be discharged or subjected to the next stage i.e. secondary treatment. Primary treatment removes about 60% of suspended solids from wastewater.
3. Secondary Treatment: The prime objective is the further treatment of the effluent from primary treatment to remove dissolved and suspended biological matter. The biological solids removed during secondary sedimentation, called secondary or biological sludge, are normally combined with primary sludge for sludge processing. Secondary treatment may require a separation process to remove the micro-organisms from the treated water prior to discharge or tertiary treatment. Secondary treatment removes more than 90% of suspended solids.
4. Tertiary/Advanced Treatment: Tertiary treatment generally follows secondary treatment and aids the removal of those wastewater constituents which cannot be removed in secondary treatment. Treated wastewater is sometimes disinfected chemically or physically (for example, by lagoons and microfiltration) prior to its discharge into the receiving environment (sea, river, lake, wetlands, ground, etc.)
The following are frequently used as selection criteria: desired effluent quality, anticipated construction and operation costs, land availability, energy requirements, and sustainability considerations.
