Pioneering Research in Wastewater Treatment

Research conducted at the Station laid the foundation for modern
methods of wastewater treatment used throughout the world:
 

• Use of sand filters
• Use of trickling filters
• Use of contact filters
• Activated sludge process
• Coagulation and sedimentation

• Septic tank design, operation and performance evaluation
• Percolation through soils
• Industrial waste treatment
• pH adjustment
• Toxicity reduction

Shown above are pilot wastewater treatment experiments at the Station.
 

Pioneering Research in Drinking Water Treatment

Research conducted at the Station also laid the foundation for modern
methods of drinking water purification used throughout the world:
 

• Slow sand filtration
• Intermittent sand filtration
• Rapid sand filtration
• Coagulation
• Aeration

• Disinfection (lime and chlorine)
• Taste and odor removal
• Corrosion control
• Iron and manganese removal
• Fate of radioactivity during treatment
