| Abstract | The principal objective was to demonstrate, on a pilot plant scale (65,000 gallons per day), that a combined biological-chemical treatment scheme can effectively remove organic carbon, phosphorus and nitrogen from wastewater. The treatment scheme consisted of: Organic carbon removed by activated sludge type processes; Phosphorus removal by chemical precipitation with aluminum, and Nitrogen removal by biological-denitrification techniques. Process design loading factors were developed. The total cost of wastewater treatment was estimated. |
