Introducing the new Zetasizer WT - automatic, online monitoring for stable and cost-effective water treatment.

We are hosting an introductory webinar about the new Zetasizer WT on 17 June 2015. Register here: www.malvern.com/zetasizerwtlaunch

Clarification, a process of coagulation and sedimentation to remove suspended particles in raw water, is a critical step in drinking water purification. The Zetasizer WT continuously measures zeta potential, a parameter that directly quantifies the charge of colloidal particles in the water and predicts the likelihood of coagulation. Setting upper and lower zeta potential limits, beyond which floc formation is poor, provides the plant team with a defined target for safe operation and a simple and clear means of tuning coagulation. The technology reduces reliance on largely manual and user dependent alternatives which provide little insight as to how to alter operational parameters in response to changing conditions, and provides a level of confidence and specificity absent in other online techniques.

The Zetasizer WT is a standalone system that can be installed on either new or existing water treatment plants. It requires only a standard power supply, a pumped sample water feed and a covered site. Results are reported in [mV] and are displayed locally as well as sent to a central control facility. Zeta potential is measured at a user selected rate of up to one measurement every two minutes to provide data resolution that is sufficient for the control of rapidly changing processes. These data improve the effectiveness of manual decision making and, at the same time, provide a secure platform for automated coagulant dosing control.
