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.

Under the Bioterrorism Preparedness and Response Act, all emergency response plans, at a minimum, should include plans, procedures, and identification of equipment that can be implemented or used in the event of an intentional attack on a water treatment system. One fast-testing method for evaluating water pollution is Severn Trent Services' Eclox Rapid Response Water Test Kit, which uses chemiluminescence, which is used to measure the amount of light generated when a water sample is combined with reagents.

Pump Up the Volume   Water & Wastes Digest October 2003   G. Michael Strombach
The Grand Coulee Dam releases, on average, 110,000 cubic feet of water per second, primarily for generating electricity. Controlling huge volumes of water requires giant-sized equipment, which can sometimes face giant-sized problems when problems occur. Three of the 24 turbines are rated at 805 megawatts and are some of largest turbines ever built. Making sure they consistently function in a reliable manner can present significant hurdles for maintenance engineers and mechanics.

The O-Zone: Today's Lesson: Ozonation of Cooling Towers   Water Quality Products June 2003   Roger Nathanson
The objective of ozone use with cooling towers is to maintain the highest purity of water with the least amount of water waste and chemical use. Chemical use in cooling towers leads to ever-increasing total dissolved solids (TDS), which must be reduced by eliminating water (blow down/bleed off) and then refilling with raw/lower TDS water. This is a vicious circle that will never end unless one
