✦ Synopsis

The application of digital computer control to municipal wastewater treatment processes is steadily gaining popularity. Within the next few years this mode of control is expected to become a standard feature of larger wastewater treatment plants. The purpose of this paper is threefold: first, to acquaint those outside the wastewater industries of the general concepts of wastewater treatment so they may appreciate some of the requirements imposed on the control computer; second, to present the overall control laws that regulate the feedback control of pure oxygen activated sludge and anaerobic digestion processes; and third, to describe the control system architecture and present the general philosophy of on-line closed loop control of Metro Denver's high purity oxygen activated sludge process.

## Abstract Various measures were tested at a full‐scale wastewater treatment plant to control sludge bulking by type 0041 and 0675 filamentous microorganisms, instigated by highly variable wastewater loadings from a food‐processing facility. Intermittent aeration on a 1‐h on 1‐h off basis was foun
