Using Baseline Monitoring Techniques to Assess Filter Run Performance   WWDmag.com January-December 2005   Michael J. Sadar and Kathleen Bill
Determining if a filter run is approaching a breakthrough condition is a daily challenge for water treatment plant (WTP) operators. Current techniques look for upward trends in either turbidity or particle counts of the filter effluent. However, this does not consistently predict actual filter breakthrough. This study’s objective is to determine if data from different particle detection technologies can be better utilized to characterize filter performance.

The Application of Simplified Process Statistical Variance Techniques to Enhance the Detection of Filtration Integrity Loss   WWDmag.com January-December 2005   Mike Sadar
Process monitoring for loss of filtration integrity is often performed using basic light scatter detection methods such as turbidity and particle counting. These methods monitor for the presence of particles in the filtration effluent (permeate). The industries where these parameters are most widely used include drinking water and ultra-pure water production. The recent upward trend in the application of membrane systems for drinking water production enhances the need for technologies with higher sensitivity and greater reliability because the loss of filtration integrity could directly impact human health.
