So I have been in a discussion with a good friend about diatoms, Dino’s and silicates. Lots of info about those things in previous threads but cause of diatoms and Dino’s not really at issue here. The basic question was if DI media dwell time had any effect on DI exhaustion rate. This was prefaced with the understanding that 0 TDS is not an indicator of exhaustion.
It is my understanding that colloidal silica is mechanically filtered and ionic silica, along with any other ionic contaminants, is addressed with DI media. Since that exchange process happens on an atomic or molecular level, It would seem pretty linear for the main method of DI media exhaustion to be volume with a minimum requirement for dwell time at best. I was wondering if anyone had any input on that subject. Thanks.
