1. Used to prevent biological fouling of an R.O. membrane during storage.
2,3,4. Essentially "detergents" used for membrane cleaning of mineral and biological deposits.
5. Assists in keeping "desolved salts" into groups large enough for the membrane to filter out. R.O. membranes will filter out particals down to the size of a virus.
6. Ph adjustment of product water.

Hope this helps...

Thanks, I agree with you. I'm new at this... I did a job in Angola, Africa, once. There the R.O. plants' chemicals had been stored in direct sunlight, and the lables badly faded. The result was the operators (whose english wasn't fluent) weren't sure what they were doing. I was sent in to "clean up the mess". I suppose a "knee jerk" reaction caused my answere.
