Optional features in RO system design

摘要

Optional features for a reverse osmosis (RO) system become a type of wish list. Dealers (or their customers) may say, "I wish I could have all the bells and whistles on the unit, but I don't want to pay the added cost."rnHowever, although they add cost, a few such features add value and save RO system maintenance time and expense. Here are features I clearly would not overlook and always include:rn1. Flowmeters. Last month, we determined that pressure is a byproduct of flow, and how can we determine flow without flowmeters? How many times have you tried to fill a bucket while timing it to determine flows (and got yourself and the area soaked)? Not having flowmeters is like driving your car at night without the headlights on — it doesn't make sense.
