PROCESS AND APPARATUS FOR RESTRICTING THE GETTING INTO THE OPEN OF THE ODOUR EFFECT OF SEWAGE IN SEWAGE SYSTEMS HAVING VARIOUS ENGINEERING STRUCTURES, OR POSSIBLY FOR SIGNALING THE ODOUR EFFECT

摘要

The method involves the measurement of the oxygen demand of the waste water, in the pipeline and/or at equipment such as pumping stations. If the oxygen demand exceeds a certain level, air is added e.g. at a pumping station. Alternatively or coincidentally polluted air may be diverted to a de-odoriser. An alarm may also be initiated. - The equipment comprises a probe for the measurement of oxygen demand, a signal processor, air injection and/or air deodorisation
