Monitoring and Maintenance of Oxygen Transfer Efficiency
To ensure consistently high performance over time, regular monitoring of the key parameters of the aeration system is essential.
At plant start-up, it is recommended to record the air line pressure, which serves as a fundamental reference for operational efficiency control and should be checked periodically.
An increase in pressure compared to the initial value may indicate the progressive clogging of diffuser pores due to scaling. When pressure exceeds 100 mbar, preventive cleaning actions are recommended.
A first intervention consists of blowing air at a flow rate approximately twice the maximum operating flow, in short cycles of about 15 seconds, alternated with 15-second pauses, repeating the cycle three times consecutively.
At the end of the procedure, the system should be returned to normal operating conditions and the pressure checked again: a reduction in the initial value indicates that the treatment has been effective.
In the case of more persistent scaling, in-line cleaning during plant operation can be carried out using specific acidic solutions such as formic acid, acetic acid, or citric acid, selected according to the type of deposits.
