Some manufacturers offer "sea-water" range chlorination equipment. Works from 5,000ppm to 35,000ppm and above. You actually get longer lasting electrodes, as they get a lot less wear due to lover oxygen generation at higher salinity levels. Also, SWCG will consume less power to produce same...

It the pool fiberglass? Known issue with this type of pools, due to static charge build-up when pool pump operational. Chlorinator, water pump, water heater or any other electrical equipment in contact with the water can cause electricity leakage. Electrician will have to perform standard...

Few good advises here, generally calcium carbonate buildup on catalyst is result of CSI been positive. Addition of automated pH control tend to reduce the issue by large margin. Remember that amount of calcium carbonate buildup directly proportional to CSI and amount of current passed thru the...

OK, basically leave sanitation as is, with chlorination as primary disinfectant. But add chemical controller for system management.

I am playing with idea I had now for some years, what would Ideal Chlorine Generator look and work like? What is really needed by pool owners? Not the marketing ideas we all get sold but real needs? For example, let's go extreme here: Do we need chlorine at all or we need sanitation? It may...

There are few possible reasons. One I came across was on large commercial pool. It turned out that water had large amount ultrafine dust particles that filter could not pickup. It was coming from surface of the pool, old paint. When water was passing electrolytic electrode particles where...

Good advice mknauss Ru02 catalyst on titanium substructure specified for temps just below 100. Above this, you will experience accelerated wear. CSI is indirect issue, as electrode calcifies it calcium carbonate creates isolated parches on the anode coating. SWCG will see it as increase in...

VSPumps are not straight forward saving. Once you slow down the pump your power consumption reduces but so is pump efficiency due to pumping losses. You will end up running pump longer hours to compensate, if you still want to turn over pool water once a day. When you model VSP and hydraulics of...

AOP systems are known to be most effective for in-door pools for dramatically reducing combined chlorine levels. This is main reason they are used by commercial installation, to assist with water to comply with regulations. Installation normally looks like ->pump->filter->AOP-SWCG->outlet...

Agree, higher that recommended salinity levels force transformer based powersupply used in SWCG to shift thermal load from equal distributed to transformer or other components depending on electronics design. This cause parts to operate at elevated temperatures, over the long time this will...

From point of view of chlorine, it will just start generating some Sodium Hypochlorite, should not affect much apart from you needing to watch it over next few weeks and adjust output accordingly. What may have some affect is increase in pH drift but it minor, and effect salt may or may not have...

Hello bubblehead, got your charts and had a look at them today. ORP seem to be working correctly indicating ‘water oxidizing potential’. You can see how it rises in mid-night and drops out to mid-day (probably due to UV and bath load). So from electronics/software point of view there are no...

I will take at look at it : prodiction[@]autochlor.com.au

Re: R&D / ORP vs H2 H2 seemed to affect ORP readings only. The colorimeter indicated stable read out of both free and total chlorine. So did the chlorine demand test. All figures but ORP was OK.

R&D / ORP vs H2 In the tests we performed with ORP sensors VS H2 generated by chlorinator there was no solution found, other than use commercial cyclones (machine that removes H2 from the water flow). On the problematic installation we observed "unstable" ORP readout while chlorinator was...

Hello bubblehead, guys here covered topic well, not much to add. I can suggest you to come back to ORP system manufacturers and request them to 'alter" programming for the unit as the trial. What you need to try is to sample ORP after chlorinator been off for some time: 1. Chlorinator - off/...

I cannot comment long term exposure but I believe the health department guidelines for pool water sanitation take in to the account that swimmers do shallow some QTY of water while swimming and also have eyes and ears exposed. Therefore water quality should be acceptable for random / emergency...

Titanium, I work for chlorinators manufacturer. We perform a lot of R&D, some of the tests are long shoot projects that end users will see coming out in 5-6 years from now. Acid damp tests are normally used to test performance of chemical sensors and as well as electrode "cell". They are also...

On one of the test pools we have, some tests we done needed sharp change in pH of the pool water. We need to drop pH 8.2 down to 6.9 or about. The only way to do it quickly is to feed acid via skimmer. Some time we need to dump about 40 Lt of HCL in one go (under one minute). Based on the test...

Interesting data Cliffs, I have different test results on efficiency VS current density. Unless you are talking far extremes, I have tested variations in size of about 100% retuning stable, linear results of no change. Also, there is another variable which is speed of water flow thru the plates...

Poolsean is right. Most chlorinators manufacturers use secondary data such as cell's operating parameters to indicate "approx" salinity. You cannot rely on this system.It is only an rough guide and works only while cell has no calcium deposits and in good working order. So periodic water test...

cliff_s is right, you better off with oversized machine than undersized! In regards to how big machine do you need, you first need to answer " what is your chlorine demand". If you do not know, than take recommended average machine and go next size up. example: 25 gram chlorinator will do: 3000...

Sometime people refer to "muriatic" acid as a diluted form on HCL (hydrochloric acid). It is the same acid.

First of all, the best source of info is instruction manual or contacting SWG manufacturer direct, as ther maybe some specifics to cleaning electrode for your particular SWG / MODEL. The general cleaning procedure is to dip electrode in solution of HCL (diluted to safe levels). Normally...

lsbarkley, do you have kids at home? I wonder if they damp some water soluble paint :roll: :roll: Algae can survive at 7.5ppm FC if it held steady over the time as it develops immunity to FC. So if you really want to stress it, it must be a very high rise in FC in very short time. Like 15ppm...

Depending of momentary water chemistry deposits of calcium can be both weak / soluble and hard / unsoluble.

Body waste is a nasty compound and it takes a lot of chlorine to neutralize. Our company have sold number of large commercial chlorinators like this one : http://www.autochlor.com.au/details.asp ... l=SMC-3000 to the water parks or dolphinariums I must say. Due to waste animals generate the...

OK, here is the hint if i understood your set up correcly. Do you happen to have self cleaning chlorinator? 8) As electrolytic cell is an last part of filtration system the calcium flakes that it produces when selfcleaning will not get trapped by filtration system. This is normal. As water...

I would guess that when you compare the same quality chlorination system and CU/AG system, SWG will cost more due to higher cost of anode material used. CU/AG electrodes are cheaper and powesupply module for them can be less sophisticated due to simplicity of driving sacrificial anode. But...

One important comment about driving cell with AC voltage is it's lifespan. Every time you revere the anode you damage it. Reversing cell every 1/50th of the second will kill it very quick. Anode material manufacturers usually state maximum reversal rate when the supply anode to SWG...
