Need help?Do you have a question about the Grundfos BACMON and is the answer not in the manual?
The GRUNDFOS BACMON is a bacteria sensor designed for real-time monitoring of bacteria in water. It utilizes a specially developed imaging technique for analysis, making it suitable for indoor, frost-free waterworks buildings and pumping stations. The product is intended for this specific use, and for any other applications, Grundfos should be contacted.
The BACMON operates as an automatic intelligent microscope, employing 3D scanning optics to measure total bacteria count per milliliter and total non-bacteria count per milliliter. Its measuring range spans from 0 to 1,000,000 objects/ml (bacteria and non-bacteria). The device performs batch sample taking through a flow cell with wide channels (2 mm width) to prevent clogging. Each sample involves a scanned volume of 6 µl and uses 150-250 ml of water (with standard settings). The automatic continuous sample taking has a cycle time of approximately 10 minutes.
The product features built-in system diagnostics, including a flow cell pressure sensor, a sample temperature sensor, and flow cell fouling monitoring. It provides real-time data and status updates through its operating panel, which includes a display, alarm and status LEDs, and control buttons. The device can communicate data online via web/app, offline through download, and supports SCADA integration via API. A GSM connection with a SIM card connected to a 3G network is installed for internet connectivity.
The BACMON is designed for ease of use with a clear operating panel. The menu structure includes "Home," "Status," "Service," and "Settings" tabs. The "Home" screen displays current status and results, including bacteria and non-bacteria concentrations, and flow cell status. The "Status" menu allows users to view last results, sensor data (board temperature, flow cell temperature, flow cell pressure), current alarms, and warnings related to hardware and water quality.
The device is largely automatic, requiring minimal manual intervention during normal operation. It starts sample taking automatically when the main switch is turned on. The "Service" menu is accessible for maintenance tasks, and entering this mode will temporarily stop sample analysis. The display uses color-coded indicators for flow cell status (e.g., yellow for fouling) and alarm/warning backgrounds (red for alarms, yellow for warnings).
Regular maintenance is crucial for the product's expected lifetime of 5-8 years. The manual outlines several maintenance tasks:
Alarms and warnings are indicated by LEDs and displayed with error codes. Hardware alarms stop the product, while water quality alarms allow it to continue operating. Alarms can be manually cleared via the operating panel or the water quality server interface by Grundfos service specialists. Warnings disappear automatically once their cause is resolved.
The product must be drained before transport or storage for extended periods. When taking the product out of operation for disposal, it must be returned to the manufacturer for scrapping and not disposed of as unsorted household waste.
