I'm working on the design of an equalization basin for recycling backwashed water (this includes filter to waste as well) to the headworks of a traditional water treatment plant. Public health requires the recycled water to be no more than 2 ntu when sent back to the headworks.
I need to determine the detention time of the eq tank in order to avoid under sizing it...
What kind of correlations between turbidity and settling rates can I assume?
Thanks in advance
