I am doing research for a story and I wonder if anyone can point me to research on turnover? In particular, has any research been done that demonstrates what percentage of a given pool's water actually goes through the filter during "a turnover?"
Near as I can tell, "turnover" is theortical, and the proof that the correct turnover rate has been chosen is in the clarity of the pool?
Any citations, links, explanations, graphs, charts, drawings on a napkin, etc. would be most appreciated!
Thanks for your help,
