I’m doing a research in college to find a method safer then chlorine to disinfect a swimming pool. Chlorine reacts with organic products to make chloramines while other popular methods found don`t seem as effective without the use of chlorine.
I have found some sites, such as azurwater.com, claiming that electroperoxydation does not use any chemical and there is no direct or indirect pollution involved. The concept is patented in France and could be applied to swimming pools as well as anytime you want to disinfect water. But I wonder if the titane electrode used is stable and the ions OH- and the hydrogen peroxyde (H2O2) produced, both helping for a lasting disinfection power, could have reverse effects on us, humans.
Explanations and sites are all welcome!
A few points:
-Chlorine is used for pools yes, but Bromine are also popular, and I see some lithium products being sold… you should look at an on line pool store to see what is currently available.
– The electro..what ever, is just another way to kill bacteria.. perhaps it could work, what is the amount of the H2O2 that will be created? when you add that to pool water (assume a 40,000 gallon pool) what is the concentration? is that enough to harm humans?… well if this machine constantly kicks out the H2o2 then the pool will (eventually) become a pool of Hydrogen Peroxide, and everyone will have blond hair.. so you will have to remove the peroxide somehow..(see if the french found a way to do that… they all seem to still have dark hair) you probably have to add another chemical, or change the water so often…
So how else could you remove bacteria from a pool? … Find out how you kill bacteria from other places, and see if you can apply that technology to pools… (extreme heat and UV come to mind)
I am appearing for my CCNA exam on 21st. I read somewhere in a forum that whenever the Pearson VUE sites goes under maintenance, new questions are added to the CCNA pool. Currently Pearson VUE site is under maintenance. Is the information of the forum true?
Can anyone also tell me if the test engine of cisco is web based which is operated the Pearson VUE or is it a kind of desktop application or something else?
Please answer ASAP.
Thank in Advance
Pearson VUE offers innovative computer-based testing solutions through secure, electronic test delivery. Pearson VUE provides licensure and certification. It is myth that site goes under maintenance n bla bla. CCNA questions are different every time exam. so its better don’t think about it n prepare for ur exam.
I have an above ground pool, we haven’t used it in weeks because of the weather, but we’ve kept chemicals in it. Today, there is a wide green circle all the way around the pool and even on some of the pool walls. I have vacuumed it, back washed it, took a rag and literally wiped the walls down. Then I loaded the dispenser up with chlorine tablets and used 1 gallon of shock.
When I used the testing strip (before putting the chemicals in) it said the PH was normal, the CL was normal and the Alkalinity was super low. Now after putting in the chemicals, the water is super cloudy. Did I do everything I was suppose to, and is there something else I could do to clear up the problem?!?!??
It sounds like algae. Algae causes the slimy green stuff on the walls and ladder and floor, and it can also cause cloudiness. When you vacuum it and scrub it, you are stirring it up in the water and that’s what makes it cloudy. It’s good that you shocked it first of all, and now your next step is to buy an algaecide. Buy one from your local pool store that is at least 60% or 100%…you can get the 5% stuff for like five bucks but that stuff won’t do much for an existing algae problem, trust me. Put in the algaecide about 24 hours after shocking your pool. If it’s been a few days since you shocked your pool, you’ll want to shock it again, wait the 24 hours and then put in your algaecide. Keep up with the vacuuming, etc. Algae is common when the pool has not been used for a while. I work at a pool store and at this time of the season the algaecides are flying off the shelves like crazy.
