Combined aeration and mixing system and its use in practice

Abstract

The article deals with combined systems, which are mainly used in wastewater treatment plants for the purpose of aeration and mixing. These systems are mainly installed in activation reactors, but their use is also possible, for example, in sludge storage tanks. The combined systems are capable of guaranteeing the required values of relevant monitored pollution indicators at the WWTP effluent. The aim of this article is to describe the activation reactor control algorithm with the combined system. Reliable functionality is proved by the presented average values at the WTP effluent, which meet the required emission limits set by relevant permits.
