An operating logbook is a central component of the documentation and monitoring of water treatment and wastewater treatment plants. It serves to seamlessly record all relevant operating data, events and measures that occur in the daily operation of a plant. These records are not only important for optimizing plant operation and planning maintenance work, they are also often a legal requirement in order to be able to prove compliance with environmental and safety regulations.

Technical background
The operating log is kept to document the operating status of the system as well as its performance and compliance with legal regulations. These records are crucial in order to be able to carry out a well-founded process analysis and to detect and rectify faults or anomalies in plant operation at an early stage.
An operating diary usually includes the following contents:
Operating data: This includes all operating parameters recorded during system operation. Typical data includes:
- Flow rates of water or waste water
- Temperatures and pressure values in the systems
- pH values, conductivity, oxygen content and other chemical parameters of the water
- Sludge volume and solids content in the case of wastewater treatment
- Data on consumables such as chemicals, filter media or membranes
Operational events: The operating diary is also used to record unplanned events, such as
- Malfunctions or anomalies in system operation
- Failures of system components, pumps or control systems
- Emergency measures or repair measures taken to restore normal operation
- Unscheduled shutdowns or production stops
Maintenance work and servicing: All maintenance work or servicing measures carried out are documented in detail to ensure that all system components are regularly checked and serviced. This includes:
- Cleaning filters, membranes, pumps and aeration systems
- Replacement of wearing parts
- Calibration of sensors and control systems
- Testing of safety-relevant components
Process optimization and adjustments: If process adjustments are made during operation, e.g. changes to the dosing of chemicals or operating parameters, these measures are recorded in the operating log to track the effects on plant operation.
Reporting: The plant logbook is often used to create regular reports for environmental authorities or internal quality management systems. These reports contain the most important operating data and serve as proof of compliance with environmental regulations and limit values.
Importance of the company diary in practice
In industrial water and wastewater treatment, the operating log fulfills several crucial functions:
Monitoring and control: The operating logbook helps to closely monitor the operation of the system and quickly identify faults or inefficient operating modes. By documenting operating parameters, anomalies can be detected and rectified at an early stage before they lead to serious problems.
Analysis and optimization: The collected data makes it possible to analyse system operation over a longer period of time and identify potential for optimization. This can relate to the adjustment of process parameters or maintenance planning.
Legal protection: In many industries, keeping a logbook is a legal requirement. Compliance with environmental regulations and emission limits must be regularly documented and proven to the relevant authorities. The logbook therefore also serves as legal proof that the company complies with the regulations.
Safety management: The operating log also contributes to plant safety by ensuring that maintenance and safety checks are carried out and documented properly. This is particularly important in areas where hazardous substances or highly contaminated wastewater are handled.
ALMAWATECH and the operating logbook
At ALMAWATECH, the operating logbook is an essential part of operational management. ALMAWATECH supports its customers in keeping and maintaining operating logbooks to ensure complete documentation of plant operation. This includes
Automated acquisition and evaluation of operating data using modern SCADA systems (Supervisory Control and Data Acquisition), which enable remote monitoring and automatic reporting.
Regular reports and analyses of operating data that enable the condition of the systems to be continuously monitored and optimization potential to be identified at an early stage.
Compliance with legal requirements through careful recording of all relevant operating data to ensure conformity with environmental regulations.
Training of operating personnel with regard to the proper management and maintenance of the operating logbook so that all operating events and data are correctly recorded and documented.
Conclusion
The operating logbook is an indispensable tool for monitoring, documenting and optimizing the operation of water and wastewater treatment plants. It not only serves as a basis for process control, but also as legal proof of compliance with environmental regulations. By carefully and continuously keeping an operating log, faults and inefficiencies can be identified and rectified at an early stage, thereby optimizing plant operation and reducing costs.
With the support of ALMAWATECH, companies can ensure that their logbooks always comply with legal requirements and are used as an effective tool for process optimization.
