Wastewater Treatment Optimisation Provides Cost Savings
Aug 19 2010
Author: Dr Michael Haeck on behalf of Hach Lange GmbH
The operators of wastewater treatment plants constantly seek new opportunities to improve plant efficiency and environmental performance. In order to achieve this they need to be able to maintain the effectiveness of the treatment process, producing a consistent discharge within consent limits, whilst minimising inputs such as energy, labour and raw materials.
As technology advances new opportunities materialise and this article will outline the considerable benefits that can be obtained from the latest sensors coupled with a new breed of realtime controllers. Improvements in
the accuracy and reliability of sensors, coupled with a new facility providing information about the sensors’ performance, in addition to the measurementitself, means that real-time control (RTC) has become very reliable which means that it has become an attractive option in a large number of applications.
HACH LANGE has developed a set of standardised control modules, enabling the application of processes improvements and optimisation strategies without the need for complex programming and expensive
customisation.
In combination with HACH LANGE sensors, Nutrient Removal and Sludge Treatment Processes can now be easily optimised in order to achieve savings in aeration energy and chemical consumption, even
on small waste water treatment facilities.
