1) in my pool ALL the water goes through the cell. there is no bypass. Then it splits to spa and pool. Yes the super chlorination effect only happens when the chlorination is doing it thing. Still all the water goes through the cell and there is a greater chance of the super chlorination effect at any given time during the cells cycle.1: "All the pool water" is not run through an SWG cell. A small fraction is and is chlorinated and is returned to the pool where it is diluted. Really this is the same thing that happens when chlorine is introduced via a jug of liquid chlorine. In fact if the "super chlorination" thing is true then liquid chlorine would be better since it actually chlorinates the water it touches more than an SWG cell which really only raises the FC of the water flowing through it by a few PPM. For example: a T-15 cell produces 1.45 pounds of chlorine in 24 hours. That would be roughly 1 ounce per hour. 0.016 ounces per minute. The minimum flow rate for that cell is 11 GPM. So this means that at the absolute slowest operational speed you will see 11 ppm FC introduced to the water flowing through. That's not that much, really. A pool with 80 CYA and manually chlorinating might see the entire water reach that level for extended periods of time, not just a few seconds through the pipes and then diluted with the rest of the water.
2: This is the same argument made by UV advocates and falls short the same way. As mentioned above this only happens with the water inside the cell as it passes it is of little benefit when CC exists in the bulk water. CC is broken down quite readily by sunlight and maintaining proper chlorine levels and thus should be minimal in any TFPC pool, not just SWG ones.
3: The CYA is different because SWG's produce chlorine slower and more regularly and thus benefit from having more protection from sunlight.
4: "I was told this so I will repeat it as fact" is not a very good habit to get in to. Anyway, if it is true then the same effect could be accomplished by raising the salt level of a manually chlorinated pool.
5: Your claim was that, "The electrolysis process within the cell has a some beneficial side effects that you don't get by just dumping liquid CL in the water. " Point 5 is accurate but irrelevant to that claim.
As I have said and will continue to say, there are enough positive aspects to an SWG for them to be well respected pieces of equipment around here. They don't need misleading comments about their ability. Chlorine is chlorine.
2) Maybe.. I'm speaking of SWGs.. in a pool chlorinated with liquid chlorine the CCs are left to degrade over time.
3) There you go!
4) I am a physicist by training.. spent much time with chemists.. If you require a peer reviewed article I'm sure I can dig one up to provide a proper citation. I figured a discussion of molecular reactions involved was beyond the scope of this thread.
5) It is not irrelevant to the post I was commenting on.. The biggest difference between the delivery of chlorine to the pool between and a SWG, is I don't have to get the chlorine from the store and all the overhead that is involved with it, gas, time, effort.
Love the debate.. I'm sure the OP.. got a lot more information than intended.
