A Sewage Treatment Plant (STP) is designed to treat domestic and commercial wastewater by removing suspended solids, organic matter, harmful bacteria, and other contaminants before the water is safely discharged or reused. At Daichi Kurita Aqua-Air, our STP systems are engineered to deliver reliable performance, consistent treatment quality, and efficient operation for residential, commercial, and industrial applications.
Our sewage treatment plants use a combination of physical, biological, and chemical treatment processes to convert wastewater into treated water that meets environmental discharge and reuse standards. The system helps reduce pollution, conserve water resources, and support sustainable operations.
How It Works
The treatment process generally includes multiple stages to ensure effective purification:
Preliminary Treatment – Removes large solids, grit, and floating materials from incoming wastewater.
Biological Treatment – Uses beneficial microorganisms to break down dissolved organic pollutants.
Secondary Clarification – Separates biological sludge from treated water.
Tertiary Treatment – Further improves water quality through filtration and disinfection for safe discharge or reuse.
