A Sewage Treatment Plant (STP) is a system designed to treat wastewater and remove contaminants from it. Sewage treatment plants are typically used in homes, businesses, and industrial facilities to treat wastewater and remove contaminants such as solids, oils, and metals. The treatment process involves a series of steps that are designed to reduce the number of pollutants in the wastewater, allowing it to be safely discharged into the environment. The most common type of STP consists of a series of tanks, filters, and pumps that are designed to remove pollutants from wastewater before it is discharged. The package STP typically includes the following components:
1. Flow Equalization Tank: This tank is designed to store and equalize the flow of wastewater entering the STP. The tank helps to ensure that the wastewater entering the STP is evenly distributed and of consistent quality.
2. Preliminary Treatment Tank: This tank is designed to remove large debris such as rags, sticks, and other solids from the wastewater.
3. Primary Clarifier: This tank is designed to separate solids from the wastewater. A settling process is used to separate the solids from the wastewater.
