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.
Optimization Of Water Treatment Using Zeta Potential
Drinking water in the US and developed nations of the world is treated to remove contamination of foreign materials, both mineral and organic.
Controlled Coagulant Dosing Utilizing Zeta Potential In A Direct Feed To UF Approach
San Jose Water (SJW) decided to implement a novel coagulant dosing control approach for purposes of achieving the following: limit UF membrane fouling, mitigate rain event turbidity spikes, and conserve operating costs.
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.
Upcoming Webinar: Zeta Potential And Optimizing Coagulation In The 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.
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.
What Facility Managers Are Saying About Online Zeta Potential
A chat with Larry Wilt of American Water/ Tolt Water Treatment Plant in Seattle, WA.
On-Line Zeta Potential For Water Treatment
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.
