Microbial Control for Waste Water Reuse

Industrial Process Water

Water resources worldwide are increasingly coming under pressure, leading to water scarcity and a deterioration in water quality. In particular, climate change, unpredictable weather patterns and drought are contributing significantly to the strain on the availability of freshwater, arising from urban development and agriculture.

The ability to respond to these pressures can be improved by wider reuse of treated waste water, limiting extraction from surface water bodies and groundwater bodies, reducing the impact of discharge of treated waste water into water bodies, and promoting water savings through multiple uses for urban waste water, while ensuring a high level of environmental protection.

The European Parliament enacted regulation 2020/741 that defines the necessary quality controls and quality requirements for the reuse of urban waste water, primarily for agriculture.

The requirements towards microbial controls are based on a risk assessment from the perspective of the downstream use of water. Required tests always include a quantitative detection of E. coli and, if a possibility of aerosol formation exists, the quantitative detection of Legionella.

Wate Water Reuse

rqmicro.COUNT enables effective quality control in waste water reuse applications through:

  • Very fast and quantitative detection of Legionella and E. coli in treated waste water
  • Actionable results based on single-cell counts of viable bacteria that support treatment optimization and validation
  • Implementation of effective procedures based on on-site monitoring of microbial risks
