Zeta potential or particle charge is the driving force responsible for the stability and flocculation of particles in a water treatment plant. Neutralization of this charge by oppositely charged coagulants is key for formation of stable, easily filterable floc. The difficulty faced by water treatment plants is that decisions regarding the required dose of coagulant are often based on very rudimentary measurements and tend to be operator dependent, resulting in frequent over-dosing and potential for plant upsets. Measurement of zeta potential by Laser Doppler micro-electrophoresis has been used as a laboratory method for many years and has proven to be an accurate, reliable and robust means of understanding the dosing demand. Now this technology moves on-line and delivers previously unattainable information as well as significant financial benefits to the user. Join us for this presentation launch of the Zetasizer WT – new on-line system developed specifically for water treatment plants.
