Iron removal filter for well water, refilling pool

[Jeffdha]

Pool builder suggested I hire a water service for Initial pool fill, as I'm on well water. $280 they test water and drop off filter system. I asked about filtering water when I add water to pool, company offers filter for $200, and suggested I have medium changed yearly for $70. Does this sound reasonable, does anyone have a better idea for filtering the heavy metals out when I add water?

Thank you in advance,

What exactly are you trying to filter out (I'd assume you're talking about iron but I'd rather be sure) and what kind of filter are they offering you for top-offs?

Details are important in order to know if they are selling you a real water filter or one of these high-priced "fairy-tale" systems that promises to remove everything from your water but in reality is just a paper filter...

If the sole purpose of that filter is the removal of oxidized iron then they are over charging you. A 10" Pentek 25 to 1 micron whole house filter will take care of the majority of it. There will still be some ferrous iron in the water, but you cannot filter that out.

Here is a great thread about iron. Filling now with FL well water. Iron!!! - Page 2

Here is what my set up looks like for filling or topping off the pool.

I believe it is mainly iron, not sure what else would stain the pool. Filter is sand or iron attracting medium. No paper. I hope that helps I am new to this.

Jeffdha, would you please add your state to the Location on the left side as its easier for us to answer when everyone knows your climate, etc.

Thanks in advance

Jeff,

More information please. Need an analysis of your well water including iron plus other metals, total hardness, and ph. There are some reasonably priced units that can remove iron pretty cheap but they need ph above 7.8 or so. We also need more details on what they are offering you specifically. You're the buyer so ask them to tell you specifically what they are selling you... model number, brand, media etc.

Did they by any chance call it a "green sand" filter? A green sand filter can remove a large portion of the iron from the water especially if it comes with a Potassium permanganate oxidation chamber. The filters aren't cheap to buy or maintain.

This is what one looks like.

Ok, finally got all the info together

Well water
Iron 3+ppm
Other metals all 0
PH 7.5
Alkalinity 210ppm
Hardness 525ppm
Total dissolved solids 1100ppm

This is the response I got when I asked for Specifications for the filter

I use an 8 inch times 44 inch fiberglass filter tank with a in and out valve. I use a blended media of carbon. Purchase price is 200.00 when the media is used up I charge 70 to pick up the tank and deliver it back ready to use again. Depending upon how much staining mineral content your water has the filter can last from four months to a year before it needs to be changed out.

Also water has tannins, this filter is supposed to take tannins out

If your reason for getting the filter is to remove iron, the granular activated carbon (GAC) is really the least effective way to do it. Carbon is not that great at filtering out iron and can only do so at relatively small concentrations. An active carbon filter can remove kits of other contaminants well (THMs, chlorine, organic taste and color compounds, etc). For iron though, you really need a green sand filter.

Jeffdha,
Not to offend you or get off topic but your house reminds me of Walter White's house from Breaking Bad.

No offense taken, and I will check in to the green sand filter today.

The filter's gonna take a beating when you fill your pool, but will likely be used sparingly after that. I'd be concerned first of all that whatever you get has enough capacity to filter the 19k gallons it will take to fill your pool. After that, any old filter should do for the occasional topping off.

At first I looked up the type of filter and media you described and at first read though yea I guess that could work or at least they claim it will.

Then I thought about it again. And remembered that activated charcoal is primarily used to remove chlorine from drinking water. Not really what you want in a swimming pool. The use of a blended charcoal media is a complete waste on chlorinated pool water.

Tannins which you say you have are oxidized and removed by chlorine as well so again really a non issue in chlorinated pool water.

The type of filter you are looking at and should be able to handle at least 10gpm of flow if not more. It's a good size for a side stream filter. Ask the guy you are renting it from for an iron specific media and stay away from the charcoal.

Update, this is the system used to fill the pool, I had water tested along the way. 0 iron in pool water! So I went ahead and purchased to filter they sold, it is similar to one of the ones in pic but larger, should work for a year of adding water to pool I will continue to test and post updates. The use of the filters in pic cost $285 filled over 19k with 0 iron. Expensive but I'm happy with results.



Took over 64hrs to fill because filter system reduced fill rate to 5gallons a minute. I guess I was having to much fun to take picture after it was full=)
