A major drawback of utilizing clarification/sedimentation ahead of low-pressure membranes is the issue of organic polymer addition (clarifier aid). Most membrane suppliers and design engineers restrict the use of this product to prevent potential accumulation within the membrane fiber and subsequent loss of beneficial use. Cationic polymers are s...

Automated zeta potential is rapidly expanding as a tool to regulate chemical dosing in water treatment plant processes. Zeta potential in combination with other inputs such as flow, pH, temperature and organics to minimize chemical cost and sludge disposal especially during rapidly changing conditions. This Presentation highlights incorporation o...
