Online and real time bacteria monitoring

Sep 21 2018

Today, microbial drinking water quality is monitored through either time-consuming laboratory methods or indirect on-line measurements. Results are thus either delayed or insufficient to support proactive action. Grundfos has developed a novel, optical, on-line bacteria sensor with a 10-minute time resolution. The sensor is based on 3D image recognition, and the obtained pictures are analysed with algorithms considering 59 quantified image parameters. The sensor counts individual suspended particles and classifies them as either bacteria or abiotic particles. The technology is capable of distinguishing and quantifying bacteria and particles in pure and mixed suspensions, and the quantification correlates with total bacterial counts. Several field applications have demonstrated that the technology can monitor changes in the concentration of bacteria, and is thus well suited for rapid detection of critical conditions such as pollution events in drinking water.

Grundfos Pumps Ltd is a UK leader in the supply of pumps and pump systems for domestic, commercial building services and process industry applications. Additionally, the company supplies a broad range of equipment and solutions designed specifically for water utility applications.
