The Oxydatorbox is an oxidation air supply box that is a ready-to-connect system for automated, correct oxidation air metering. It is suitable for use in the treatment of municipal drinking water and all applications where gaseous media have to be controllably metered into a liquid flow.
It is designed to control the airflow, independent of pressure, via a Bürkert mass flow controller (MFC), type 8626, which is a compact system consisting of a flow sensor, a controller and an actuator. The MFC is configured using the software supplied, which can also be used for diagnosis and communication with fieldbus systems such as Profibus and Devicenet. This extremely flexible system allows target points to be set as well as read from a remote station.
It can automatically regulate the gas quantity needed for oxidation based on different process parameters to achieve optimal results with minimal gas consumption.
The incoming air pressure is controlled by a pressure regulating valve, with a secondary valve designed to protect the Oxydatorbox from back pressure in the event of a loss of air pressure. There is also an option to have a solenoid valve, designed with a slow opening characteristic for opening the air inlet safely via an external signal. The control system can be configured for use with air or pure oxygen, depending on the process requirements.
Automated metering of oxidation air ensures constant water quality and documented and traceable processes, which removes the reliance on an experienced process supervisor to monitor the quality of water (or other liquid) and supply the necessary level of air manually via mechanical valves.
The low oxygen consumption and optimised operation of the compressors in the metered supply of air offers substantial economic benefits.
