Large amount of data is available from various sources in a wastewater treatment plant, such as process variables and parameters, equipment maintenance logs, and lab measurements. Nevertheless, this data (if stored) is often scattered in diverse formats and its full potential is often left unexploited. Thus, assessing the plant performance in a less or semi-structured fashion can be often quite challenging. Inefficient operation or even maloperation may go on unnoticed for long periods of time creating higher operating and maintenance costs or leading to safety hazards. Early signs of equipment or process failures are often difficult to detect, leading to unscheduled operational disruptions. In the absence of a plantwide perspective that could be drawn from the integration of the available data, operational improvements are often focused on the individual unit operations overlooking the performance impact arising from their interactions.
As a technology supplier and the market leader for thermal hydrolysis process (THP) with more than 50 plants in operation, Cambi is actively engaged in operations support. We are aiding our clients in taking optimal operational or business decisions. As part of our continuous effort to improve our services, we have developed the Cambi PLUS platform, a real-time plantwide condition and performance monitoring system, to address the above-mentioned challenges. PLUS relies on integrating and analysing the real-time and historical plant data and provides data-driven insight into the plant performance.
One year after the implementation of Cambi PLUS in two WWTPs, this talk aims to review and exemplifies the operational benefits of the system, including plant availability, monitoring of critical equipment’s health (lances, valves, and pumps), operation stability and energy consumption. It will include a use case report from one of the WWTPs – in Tarnow, Poland, that currently uses the platform and who has been an active participant during its development and testing phases. We will showcase their perspective on the benefits of a multi-timescale operational overview of the plant data via the Cambi Plus platform. In particular, how the various multi-timescale plant performance dashboards and the autogenerated reports can provide a valuable data-driven basis for bettering the decision making for all, from the operators to the highest levels of the plant management. Furthermore, how the built-in notifications system, that can be easily programmed to monitor 24/7 sets of logical conditions involving process variables, soft-sensors and/or KPIs, can provide automated warnings for early signs of abnormal or inefficient operation thus offering a piece of mind for their operators and plant managers.
It is worth mentioning that Cambi PLUS does not contradict the existing SCADA system in the WWTP, but is a detailed supplement to it in terms of parameters essential for maintaining continuity and reliability of technological processes. It’s adaptable according to the user’s needs and enables monitoring of the installation from any place with Internet access. Creating detailed reports and visualizing process data helps to make critical decisions to ensure safe use of the technology while maintaining the required quality.
