STP Plant is a sewage treatment plant designed to remove contaminants from wastewater, including household sewage and industrial wastewater. STP Plant typically involves several stages of treatment, including primary treatment, secondary treatment, and tertiary treatment, to remove solids, organic matter, nutrients, and pathogens from the wastewater.
The primary treatment stage involves the use of physical processes, such as screening and sedimentation, to remove large solids and organic matter from the wastewater. In the secondary treatment stage, biological processes, such as activated sludge or trickling filters, are used to further break down organic matter and remove nutrients from the wastewater.
The tertiary treatment stage is used to further purify the water and remove any remaining contaminants. Tertiary treatment processes can include filtration, disinfection, and nutrient removal.
STP Plants can be designed as package plants, which are compact and easy to install, or as larger, centralized plants that serve a larger community or region. They can also be designed for various flow rates and levels of treatment, depending on the specific needs of the application.
STP Plants are essential in preventing the discharge of contaminated wastewater into the environment, protecting public health, and conserving water resources.
