Sewage Treatment Plant (STP)

Description

Preliminary Treatment: Removes large solids like debris, stones, and plastics using screening or grit removal techniques.
Primary Treatment: Eliminates suspended solids and organic matter through sedimentation or flotation processes.
Secondary Treatment: Degrades organic pollutants using biological methods like activated sludge systems or biofilters.
Tertiary Treatment: Ensures water meets stringent quality standards by removing residual contaminants such as nutrients, pathogens, and fine particles through filtration, chemical treatment, or advanced methods like membrane filtration.
Each stage is critical for effective industrial wastewater treatment, ensuring the water is safe for reuse or environmentally compliant discharge.
