A sewage treatment plant is a system that removes contaminants from urban wastewater, which mostly comprises household and industrial waste. Physical, chemical, and biological methods are used in this treatment plant to eliminate pollutants and produce treated wastewater that is safe to drink. Sewage sludge is a semi-solid waste that is generated as a byproduct of sewage treatment. Sewage treatment is also known as wastewater treatment, and may also be referred to as industrial wastewater in a wider context. Sewage can now be handled close to where it is produced, which is referred to as a decentralized method. If this method of treatment is not carried out, it would be extremely difficult to keep wastewater under control and to deal with any problems or illnesses that will occur as a result of air and water contamination. The semi-solid waste or slurry known as sewage sludge is a by-product of sewage treatment. Until it can be disposed of or applied to soil, the sludge must be treated further.
APPLICATIONS OF SEWAGE TREATMENT PLANT :
A sewage treatment plant is driven by airflow, which encourages bacteria to expand and break down sewage. This treatment aims to create effluent that is much cleaner and more environmentally friendly. Main, Secondary, and Tertiary Water Treatment are the three primary stages of the waste treatment process. The following are the levels of sewage treatment plants: 1. Screening & Pumping, 2. Grit Removal, 3. Primary Settling, 4. Aeration / Activated Sludge, 5. Secondary Settling, 6. Filtration, 7. Disinfection, 8. Oxygen Uptake, 9. Sludge Treatment.
COSTING OF SEWAGE TREATMENT PLANT :
With just routine maintenance, these Sewage Treatment Plants are reliable and unlikely to break down. Also on difficult or constrained sites, it can be mounted. Over time, it'll save you money because you'll just have to pay for installation, fuel, and maintenance. Sewage Treatment Plant is necessary to treat water at many places and its investment is worth making it as it gives a good return for its usage within a period of time. Depending on various cost factors and other requirements its costing may vary from Rs. 3,00,000 to Rs. 45,00,000 or even more.
