Salt water chlorination for commercial pools

Posted by Gary Daniel on August 5, 2009 at 4:55pm
We have a commercial swimming pool management company, and are trying to get away from the liquid chlorine system. You can't beat a CAT controller, but the problem is getting the chlorine delivered to the pool. We have converted some pools to salt but seem to see problems develop after the first season. Any suggestions on system that last.

    States are mandating Ultraviolet Santizers for many commercial pool applications! Science has proven UV is the most efficient system for eradication of bacteria, germs, virus and algae. UV does not genrate any Disinfection By Products and simplifies pool chemistry maintenance. UV is the solution!

    Our web site isn't much, but it is www.ozonejoes.com where some info can be found. We do not sell product on the web. Liquid feeders are fine with ozone but liquid is not always available in some markets. Other markets it is the mainstay. Just remember if you add an ozonator you will have to treat your CAT controller differently. Settings will have to be increased. You will find you also use a bunch less chlorine. Some say 60%, some say as high as 90%. All depends on bather load and correct sizing of ozonator. Ozonators are often the least expensive piece of the puzzle. If you do use salt chlorination which is the premise of this forum, the best recommendation is again--add an ozonator to help the chlorinator keep up.

    Thanks for the advise. In the past eight years of doing what I do, I have avoided using erosion feeders, if at all possible. Liquid has worked great, it's just getting the chemicals delivered, is the headache. I would like to find out more about your ozone. Hope to see you at the NSPF meeting in October, in Atlanta.

    By all means, keep the liquid feeder if you have one. I also agree with another comment in this string. The proprietary tabs and exclusive territories for sales is a bust. Ozone works wonderful with either feeder, you just have to set your ORP at a much higher setting for the chlorination feed or you will never feed chlorine as the ozone makes the water much better. I have seen settings as high as 775 mv for the start chlorine feed just to keep the chlorine at the minimum level of 1 ppm. Anything lower the chlorine will not feed enough to hit 1 ppm as it may never feed.

    Why go away from Liquid? You can replace the entire system for next to nothing, its virtually maintenance free and its the most reliable feed system. It does sometimes, like a lot of things, not get used in a manner best suited for the pool, system and water though.

    And 110% agree with Dennis, add Ozone. **Properly** done you will see a massive improvement in water quality, chemical costs and therefore time spend trying to solve those issues. But an brutally expensive puck feeder that uses brutally expensive proprietary pucks? Not in my lifetime as far as I can see.

    I am using AP now. Rep coming in on Wednesday to try to address some of the problems. Hope to see you where all the industry leaders meet at the NSPF conference, October, in Atlanta.s.com

    Auto Pilot has various commercial systems that have a proven track record. They are 'sizable' to most any pool. Auto Pilot can provide a list of hundreds of successful commercial applications and testimonials. They can easily be adapted to CAT or other controllers. Due to decades of experience, Auto Pilot is not only extremely dependable but provides affordable chlorination to commercial pools.

    Another option is to combine Auto Pilot with ozone systems. The ozone does much of the heavy lifting and the salt system provides a suitable chlorine residual. The Auto Pilot / Co-Pilot system can do 80K gallons for residential pools by combining salt and corona discharge.

    It should be said that the gallonage of the pool is only one component in sizing. Bather Load / Chlorine Demand issues are key factors and critical in properly chosing the right size system.

    Hope this helps...
