Hi Thanks for your reply. I am aware of projected effective surface area calculations based on settling / rise velocity. But I am unable to get any information as to the relationship between feed TSS and projected surface area requirement. General recommendations for plate spacing is 2" but when when we handle 6000 ppm feed TSS what should be the plate spacing. How is it decided? How much TSS lamella can handle?

Hi K.V. 2 inch plate separation is fine, At 6,000mg/L TSS using the flow rate will provide you with a mass of solids i.e., 10,000L/hr will yield 60kg/hr of settled solids all things being equal. if you remove 60kg/hr of settled solids from the cone of the plate separator, you will have the ideal operating scenario.
