How to Treat Well Water

03/05/2009 11:23 AM

Hey guys. This is for a home..

There is plenty of water pressure.. lots.

The outside spigots are fed directly, and the inside water supply is in need of an overhaul.

The old softener kicked the bucket, but it could have been better form the get go.

What can be done to eliminate this pumpkin pie colored water!?

ok.. it runs clear after a bit, but you get the idea.

___________________________________________________

there are some nice expensive iron removal systems, but how does one choose?

What about loss in water pressure when adding these systems.. It would be nice to maintain a decent flow rate (gpm)

..What has worked for you?

If it were up to me, I think I'd use a dual cannister (media and charcoal??) system AND and iron remover and a softener, but what goes first? last?

is softened water going to taste funny? what about reverse osmosis?

..I'm not very knowledgeable in the water treatment department, but it's important stuff to know.. so thanks!

oh yeah.. 1" supply pipes .. and it's about 60gpm!? way more than needed.

In the UK, private water supplies are monitored at intervals by the local authority, a service that is provided as part of one's local taxes as a home-occupier.

  • Let's hope the pH is not far off neutral, for starters.
  • The colouration might be iron. It might be decaying vegetable matter (which is one of the things that would correspond with a low pH). Both of these are OK up to a point, though one won't get washing white using water with 50ppm of iron in it. It might be "ochre", which is a short-hand way of saying "finely divided brown-ish solids".
  • Don't drink softened water. The lack of calcium and its substitution by sodium ain't what the body wants. Only soften the water that goes to the hot tank and the washing machine. Make sure that the stored hot water is kept at or above 60degC, for bacterial resilience.
  • Divide the new pipework into non-potable services, like for watering the garden and flushing toilets perhaps, and a treatable stream to be turned into potable (dividing the flow puts less strain on the process units that come next, for economic reasons).
  • For the pre-potable stream, try putting a 5μ absolute filter on it and downsteam of this filter, zap the bugs with a UV lamp before immediately consuming the water (a solution that works well enough here).
  • If there's a taste to the water, or if the colouration persists, or both, then activated carbon filters downstream of the above equipment on the route to the kitchen tap should be enough.
  • If the total dissolved solids is below 1000ppm (≈ 1500μS/cm at ambient) at the tap after that lot, then the water comes close to and may even comply with World Health Organisation criteria for Potable Water. Of course, to double check, the local authority's test analysis should be reviewed, and their advice sought as to what else to do, if anything, with more process units. Most individual ions have a maximum allowable level, which will be stated on the analysis: they will be high for Chloride and low for Lead, for example, and the local authority will advise.
  • If softening is attractive, then it needs to go on the branch feeding the heater/washing machine downstream of the carbon filter, and certainly not the kitchen tap.
  • If going away for a few weeks, consider adding a cupful of thin bleach (calcium hypochlorite solution) to the supply and flush it into the system before leaving: if the water tastes like a municipal swimming pool (yuk - bloody horrible) afterwards, then it is protected! Remember to flush it through again on arriving home!

And that's about all there is to it.

These days, the equipment needed to produce and maintain home potable systems may be had from major DIY home improvement stores, and a research trip to them might prove interesting, perhaps?

Hi JE,

First off from your description I'd checkout those old pipes. The odd colored water maybe from internal corrosion the pipes in the house.

So ascertain the cause then you can best apply a solution be it replace piping and filtration or a non-salt type water-softening filter like that of Crystal Quest.

What I did with mine was to install a softener, , add a coarse filter between the pump and the softener, feed it all into a UV system, then tap off to an under-sink reverse osmosis system. No point in reverse osmosis for the toilet, bathtub, and dishwasher!

I use potassium choride in the softener. Good for those on a sodium reduced diet. Posassium also won't kill the trees.

My water was foul and full of sulpher and iron and a certain amount of germs. It is now very good, safe, with no chlorine or other additives. However, visits to the dentist have gone up since I don't seem to be getting the minerals anymore.

I'm working on using a slow sand filter to offset that lack of minerals you mention.

Trying to determine the proper treatment for water without a complete chemical/biological analysis is a good way to spend money foolishly on unnecessary and ineffective systems.

Re: How to Treat Well Water

I suffered with the same problem. There is no inexpensive solution. I put in an ozone generator system that meters ozone into the water line by use of an ejector. That water then goes through two tanks of about 30 gallons each and thence to an iron filter. The iron filter is a simple machanical filter capable of being backwashed every night. The outlet of the iron remover goes to a conventional water softener and our water is now fine. The water is a little fizzy on occassion but otherwise good.

The ozone system cost me about $5000 installed. Previously I had used a similar system but without the ozone, that one pulled air into the water system, didn't need the two additional tanks and it worked great for about 10 yrs the the filter go so clogged it stopped working. I suspect that if I had backwashed more often that system may have continued to work.

The ejector is very simple and can probably be purchased seperately. The filter can be home built and even your water softener can be rebuilt unless it has just rusted ou or something. The bed can be either renewed by something like a treatment with Iron Out.

I use a rain soft brand water softener/filter on my well water. http://www.rainsoft.com

It has worked very well for about 4-5 years and all I have had to do is keep salt in it. The installed cost of the one I use was around 5000.00 and it filters to 5 microns. The one I have has a lifetime warranty on everything but the desiccant. Before I installed it we had the problem of reddish ring stains at all the drains in the house as well as premature failure of hot water elements from the iron in the water but that is all over now.

Hey guys...

thanks for all of the input.

First of all.. The pipes are all copper in this house.. and most of those are getting replaced in this overhaul.

The water was found to have high iron, but it's not off the charts.

It actually does run quite clear.. it will run reddish only if the well pump has been off for a while

would it be out of line to add a charcoal or other?? filter AFTER the softener, but before things like the ice maker and drinking / cooking water?

newer softeners don't fudge up the taste or composition that bad .. do they? Is that the only issue?

I drank a lot of soft water growing up.. but then hey.. look at how I turned out.

it's more slippery?

Soft water areas cause, amongst other problems, more heart attacks as you don't drink some important chemicals, missing in soft water...

Quite. Softened water is high in either potassium or, more likely, sodium, and low in calcium and magnesium. As such it's not what the human body needs.

Hi JE,

Non-salt softeners are more interesting I think

Re: How to Treat Well Water

03/24/2009 9:37 AM

I am thinking the same, but what do I know..

the iron max fx-125-10 is a couple hundred more than the one that is not "fx"

but my eyes are crossed trying to see why?

I like the idea that it's better for you to drink, and better for the septic field.

...I'm assuming there is a catch?

Is it the cost of the replacement media in 10yrs?

how likely is it that rust bacteria are in the water and need to be pre chlorinated?

Is that taken care of with a drip of bleach?

I guess that some fresh water should be sent in.

..Has anybody seen or used one like this?

..thoughts?

It's a pretty fair investment

I have known those whom were satisfied, some where very satisfied and a few were ecstatic. The expense of replacement media conforms to norms; contact and request from manufacturer pricing for the past fifteen years for comparison.

I don't have answers for product specifics; contact them.

A better idea yes...a catch I'm not thinking so...No chlorine iron bacteria treatment with the Hallet UV...

Yes I intend installation this year to filter the rural water we receive which though chlorinated, we want good quality on and in our bodies so the body can function without the chemical/bacterial/viral burden, yet benefit from mineral content.
