Analysis of possibilities of the existing urban waste water treatment techniques has been presented. It is mentioned that the problem of the beat available techniques choice is inseparably linked with correction of the current normalizing system in terms of composition of not only treated waste waters but also in terms of requirements to enterprises that dispose water into a sewage network.

The physico-chemical treatment of sewage requires the addition of costly reagents. The quantities added are generally proportional to the flowrate treated. Recent progress in pollution detectors now makes it possible to measure sewage concentration continuously. This makes it possible to match the quantity of reagent added to the treated-water quality objective set. COD-SM-Turbidity relations have been determined at various sites. An assessment of the performance of a servocontrol device during the summer of 1983 is presented.
