Turbidity and temperature measurement for drinking water.

With an increasing effect of global warming, drinking water suppliers are confronted with hotter water at abstraction points (e.g., surface water from rivers, lakes, wells) as well as in the distribution network when transported to the tap. In certain areas water is stored in elevated reservoirs where especially hot temperatures during summer warm up the water before it is supplied to the end customer. But what effect does increased water temperature have?

The maximal cold water tap temperature cannot exceed 25°C (DIN EN 806-2:2005). While this value is not mandatory by drinking water regulators it is a typical value for cold water applications when hygienic tests are performed (e.g., KTW, WRAS). Microbial growth increases exponentially with temperature. The solubility of dissolved gases decreases with increasing temperature. Therefore, water temperature provides important qualitative information about water quality.

The Challenge

For this reason, Sigrist has upgraded the AquaScat S and introduced a temperature sensor embedded in the sensor head. With this feature Sigrist offers the customer an additional measurement parameter which can be used for qualitative statements about the water quality as mentioned above. Together with the high precision turbidity measurement one instrument gives the operator the possibility to map out the water quality in a semi-quantitative manner without expensive analysis equipment. The high accuracy of the Sigrist instrumentation can detect smallest changes in the water turbidity.

Customer Benefits

A crucial benefit is the measurement of turbidity with zero water loss across the entire drinking water treatment process.

Further Benefits

  • Two in one: turbidity and temperature integrated in one instrument.
  • Probe with hygienic design for direct use in drinking water.
  • Precise measurement with zero water loss.
  • A large variety of installation and interface possibilities address specific customer needs.
  • Easy re-calibration in the field without the use of toxic Formazine.
  • Easy and intuitive maintenance resulting in low operation costs.
