ABOUT MALVERN PANALYTICAL
Malvern Panalytical has been developing and supporting the use of Zeta Potential for the monitoring, control and optimization of coagulant dosage in water treatment plants for over ten years. This enables quantitative results to be used in place of rudimentary and subjective jar testing or similar less reliable methods. As a first principles technique, Zeta Potential promotes confidence in its use as a key indicator of coagulant dose effectiveness, and offers continuous real-time data to the SCADA operations team. Operators and plant engineers are then able to clearly stay a step ahead of seasonal or sudden storm water run-off effects that require swift action to keep the process running efficiently. Bench-top lab or automated online solutions make this a technology suitable for every surface water treatment plant, from the smallest rural plants to the largest high-capacity urban facilities.
Malvern Panalytical is a leader in materials characterization, creating expert solutions for the challenges associated with maximizing productivity, developing better quality products and getting them to market faster. We provide superior, customer-focused solutions and services which deliver tangible economic impact through chemical, physical and structural analysis of materials.
Our products reflect Malvern Panalytical’s drive to exploit the latest technological innovations and our commitment to maximizing the potential of established techniques. They are used by both industry and academia, in sectors ranging from pharmaceuticals and biopharmaceuticals to bulk chemicals, cement, plastics and polymers, energy and the environment.
Malvern Panalytical systems are used to measure particle size, particle shape, zeta potential, protein charge, molecular weight, mass, size and conformation, crystal structure and phase identification, mineral identification, elemental analysis, nanoparticle size and count, and for chemical identification, advancing the understanding of materials across many different industries and applications.
Headquartered in Malvern, UK and Almelo, The Netherlands’ Malvern Panalytical has additionally research and manufacturing locations in USA, Canada, and China, as well as applications laboratories around the world.

![zetasizer]( "Calculating ROI When Adding Zeta Potential To A Water Treatment Facility")
The application of zeta potential for the diagnosis and control of water treatment processes is not new. Research papers regularly cited on this subject date back decades and in fact most of the basic understanding of how zeta potential can be used to control coagulant dose remains similar to those early investigations.

![Malvern Panalytical]( "Upcoming Webinar: Cost Saving Advantages In Optimizing Coagulants In Your Water Treatment Process")
Surface water treatment, water remediation and waste water treatment are critical issues in providing safe drinking water. Control of turbidity and removal of NOM remains one of the main challenges facing water utilities. Control of the flocculation process and adjustment of coagulant dose during the course of water and waste water treatment is often a challenging step in the water treatment process.

![Malvern]( "Jar Testing Gets An Upgrade")
Jar testing is a common laboratory procedure used at water and wastewater treatment plants to determine optimum conditions for the coagulation / flocculation process. In a set of beakers a defined amount of water is mixed with varying amounts of coagulant, and through observation by a trained operator the optimal amount of coagulant can be determined.

Turbidity and natural organic matter (NOM) in the source water feeding a drinking water purification plant, particularly a surface water source, fluctuates over time. This continual change may require adjustment to the coagulant dose, pH, or polymer addition to enable the flocculation process to work efficiently. Careful management of the coagulant dose with accurate and timely monitoring can impact the overall plant performance.

![The role of zeta potential in water treatment process control]( "The Role Of Zeta Potential In Water Treatment Process Control")
Physical processes such as sedimentation, flotation and filtration remain at the heart of most process trains for the treatment of water and wastewater flows. All these processes depend on the principles relating the size, density and the charge of the particles to be removed.

![INJarTest]( "Relating Zeta Potential To Jar Testing: A Comparison Of Two Methods To Optimize Water Treatment Plant Operation")
In a water treatment plant, raw water is treated with a coagulant or flocculant. This added component leads to sedimentation of the floc. For optimization of this process, a minimal amount of flocculant should be added for optimal clarification of the water. The traditional routine has been jar testing. We compare zeta potential results to the traditional testing.

This talk is on coagulant dose management and focuses on the challenges facing those watershed areas impacted by wildfires. Keeping up with the pre-treatment process can be difficult and changes to source water run-off may last for some time. Several factors impacting water treatment during and after wildfires are discussed.

Gary Fox from Tacoma Water talks about the value that the zeta potential measurement has added to plant operations both on-line and in the lab. By installing the Zetasizer WT, from Malvern Instruments, to the water treatment process, you can make significant savings on chemicals. At Aurora Water in Colorado, United States, use of the on-line zeta potential system decreased coagulant costs by 17%, while also eliminating the needs for a rapid mixer.
