✦ Synopsis

Certain industrial processes (e.g. munitions manufacture) involve the generation of large volumes of waste with high nitrate concentration. Biological denitrification can be a very cost-effective means to deal with these wastes. and the hydraulic residence time. The mathematical model was tested experimentally, and the results indicated operating regimes that would minimize nitrite concentration. These operating and design parameters were then incorporated into the specification of a large-scale SBR system, treating 8,000 mg/l of nitrate at a flow rate of 1,022 ma/day, using four 340 ms reactors.

## Abstract A bioenergetic methodology was integrated with a modified activated sludge model No.1 (ASM1) to analyze the activated sludge process, with the treatment of soybean‐processing wastewater as an example. With the bioenergetic methodology established by McCarty and coworkers, the microbial
