Deauville Posted April 10, 2007 Share Posted April 10, 2007 Before attcking the ground with the mini-pelle I thought I'd best do some research and have now got to No.3 on the list - 'what filtration system?' It will be a modest sized, semi enterée, unheated pool with very light use and we don't fancy the idea of smelling of chlorine, or depleting the ozone layer or breaking the bank. Any advice greatly apreciated, Thanks Link to comment Share on other sites More sharing options...
Poolguy Posted April 11, 2007 Share Posted April 11, 2007 DeauvilleDon't particularly understand your question - don't think that swimmingpool filtration has any effect on the Ozone layer (I could be wrong)For designing a good filtation system you should caluclate the volumein meters3 of water in the pool and size your pump and filter to moveall of it through every 3 hours.I have written a piece on the different filtration methods earlierwhich I refer you too. So I suggest you buy a quality pump, sand filtercombination and fill it with Zeolite to get the best filtation results(1 micron)If your sanitization regime is working correctly then there will be nosmell what so ever, it only smells when you have neglected your pool.If you need specific help in the design of a pool water quality system then PM me and I woud be happy to help.Andrew Link to comment Share on other sites More sharing options...
Deauville Posted April 11, 2007 Author Share Posted April 11, 2007 Thanks Andrew, the ozone reference was in relation to the debate on the merits of saltwater systems and their possible environmental issues. Saltwater appeared to be the way forward until recently but would now appear to be dropping out of favour, or has my research reached the wrong conclusion? Are saltwater systems a good alternative in your view? Link to comment Share on other sites More sharing options...
Poolguy Posted April 11, 2007 Share Posted April 11, 2007 DeauvilleSo its sanitization systems that you were concerned about, not filtration.Using a saline solution as a method of generating chlorine is many decades oldbut has recently drawn flack from Environmental legislation, which prohibitsthe dumping of backwash water from pool using this system. As I have postedmany times, as a consequence of growing water shortages in many countries, thenotion of destroying 75 cubic meters of water by dumping salt into it isunthinkable and delinquent to the extreme. And so the system is becoming lessfavoured in exemplar countries In this climate of concern for theenvironment, more modern systems of using liquid chlorine in minimal quantitieshas grown in favour and delivery systems are now at a very sophisticated level,in all providing many times better pool management performance that the oldantiquated salt electrolyser. Your reference to the ozone layer therefore I presume is a side comment to theeffects of chlorine in ozone depletion. Its worth noting that manualsanitization using gallettes, chlorine direct injection and salt electrolysesproduce chlorine in much the same quantities, and therefore has much the sameeffect on the ozone layer. None of this is particularly significant in thecurrent ozone depletion debate as there are countless other contributors tothis phenomenon which do many times more damage - cow and sheep farts to nameone.So as a consequence, my position which I have maintained throughout 3 years ofcontributions to the forums is that the use of salt as a sanitisation method ofchoice is unsustainable, impractical and unenvironmental in the face ofalternatives which are proven to be superior in every aspect of theirperformance and their consequences.Andrew Link to comment Share on other sites More sharing options...
