Sewage Treatment Plant Manufacturer In India
Kelvin Water Technologies a prominent player in the STP market in India. The company offers a wide range of wastewater treatment solutions, including sewage treatment plants. STPs are designed to treat wastewater using advanced technologies such as:
- Activated Sludge Process (ASP)
- Membrane Bioreactor (MBR)
- Sequencing Batch Reactor (SBR)
- Moving Bed Biofilm Reactor (MBBR)
Components of a Sewage Treatment Plant
An STP typically consists of several components and processes designed to treat sewage in stages. These stages can be broadly categorized into primary, secondary, and tertiary treatment.
1. Primary Treatment
Primary treatment is the initial stage of sewage treatment, focusing on the removal of large solids and particulate matter. Key processes include:
Screening: Large objects such as sticks, rags, and plastics removed using screens.
Grit Removal: Sand, gravel, and other heavy particles are settle out in grit chambers.
Sedimentation: Suspended solids are allowed to settle in sedimentation tanks, forming sludge at the bottom.
2. Secondary Treatment
Secondary treatment aims to biologically degrade dissolved and suspended organic matter. This stage involves microbial processes to break down organic pollutants. Common secondary treatment methods include:
Activated Sludge Process (ASP): Aerobic bacteria used to decompose organic matter in aeration tanks, followed by settling in secondary clarifiers.
Trickling Filters: Sewage is sprayed over a bed of media (such as stones or plastic) covered with biofilm, which degrades organic matter.
Sequencing Batch Reactors (SBR): Wastewater treated in batches through a series of fill, react, settle, and decant stages.
Membrane Bioreactor (MBR): Combines biological treatment with membrane filtration to produce high-quality effluent.
3. Tertiary Treatment
Tertiary treatment is an advanced stage that further purifies the effluent from secondary treatment. It involves the removal of residual nutrients, pathogens, and trace contaminants. Tertiary processes include:
Filtration: Sand, activated carbon, or membrane filters remove fine particles and dissolved substances.
Disinfection: Chlorination, UV irradiation, or ozonation used to kill pathogens and ensure the effluent is safe for discharge or reuse.
Nutrient Removal: Specific processes such as nitrification-denitrification and phosphorus precipitation remove excess nitrogen and phosphorus.
Importance of Sewage Treatment Plant
Environmental Protection: STPs prevent the release of untreated sewage into water bodies, reducing pollution and preserving aquatic ecosystems.
Public Health: By removing pathogens and harmful contaminants, STPs help prevent waterborne diseases.
Water Reuse: Treated wastewater reuse for irrigation, industrial processes, and even potable applications, addressing water scarcity.
Odor Control: Proper treatment reduces unpleasant odors associated with raw sewage.
Nutrient Removal: STPs help in the removal of excess nutrients like nitrogen and phosphorus, preventing eutrophication.
Resource Recovery: Advanced STPs can recover resources such as biogas and fertilizer from sewage sludge.
Economic Benefits: Reduces the costs associated with water pollution and health care due to diseases.
Sustainability: supports sustainable urban development by managing wastewater efficiently.
Improved Quality of Life: Clean environments contribute to overall better living conditions for communities.
