Whether to use sodium polyphosphate washing machine / dishwasher filters

filters for washing machines and dishwashers with a bed of removable sodium polyphosphate.

Is it worth using such filters?
(It looks like this:



Is there any sense in using filters in the dishwasher, since it softens the water itself?

Will using the washing machine have a positive effect on washing results and the possibility of using less detergent? Will such a small in-line filter with only 100 g of active substance really give a noticeable effect?

I have hard water (kettle in stone all the time).

Attachment corrected!

It doesn't really make sense for a dishwasher - it has exactly the same thing already installed.

As for the washing machine - in my opinion it has a very poor performance. The dishwasher has a large bed, and notice how slowly it takes in water. The washing machine does this very quickly. The efficiency of this would probably be too small.

In addition, such a bed must be regenerated - note that you pour salt into the dishwasher, and she rinses the bed with brine.

Well, yes, but the dishwasher has a different bed. From ion exchange resin - the kind that can be regenerated with salt (from what I have already learned). And here is some sodium polyphosphate - after use it is thrown away and another one is poured.

It's just that I wonder just like you - high flow - and these crystals are large after all and not such tiny balls as in the dishwasher. So I don't know if it will react so quickly?

Same as Calgon or other Auchan antiKALK for 6 lines. These crystals do not catch anything, but only slowly dissolve and soften the water by binding Ca and Mg ions e in the washing bath.
Advantage
you wear it once and you don't worry about pouring something into the washing machine

Defect
-you don't know how quickly it dissolves
-you cannot set the dosage according to the hardness of the water
-accepts sodium polyphosphate ALWAYS even for rinsing in which no limescale precipitates
-possibly but bordering on it will surely not dissolve enough of these crystals to really soften the water

Write down your water hardness and I will tell you how much you would have to add to each wash. You can find out about the hardness from your local water supplier by phone or on their website.

Using it in a dishwasher is a total misunderstanding and stretching people, and in my opinion, too.

If you think it will be too small, buy something bigger

I have water with a hardness of around 16-19. A lot of limescale is deposited on everything that heats up.

1 ° n = 10.00 mg CaO in 1 liter of water and 1 ° n = 17.86 mg CaCO3 in 1 liter of water

So you have 160 - 190 mg CaO per liter of water (medium hard water http://pl.wikipedia.org/wiki/Twardo%C5%9B%C4%87_wody).
The washing machine heats up some 5 liters, i.e. 5 x 0.19 g = 0.95 g CaO.
1 g of polyphosphate binds about 0.15 g of CaO, i.e. 0.95 / 0.15 g per wash = 6.33 g of polyphosphate
Theoretically not much. But this is all you need to do when heating water.
How much polyphosphate does it contain?

If you can afford it, buy something like this http://darowoda.bazarek.pl/opis/171154/zmiekczacz-clackei10.html but the water is not suitable for drinking, but for washing and washing it is great.

100 g of polyphosphate ... well that sucks ... Assuming it has time to convert it to 75 liters of water ....

The one you write looks great with a bed of 25 kg. It's just very expensive.

But for years.
Look on the net, maybe you will find something cheaper.

Another option is to descale kettles from time to time and pour a Calgon water softener or something cheaper, such as antKALK, into the washing machine. Work the same, but the price ....

There are also reverse osmosis filters, but there is a lot of water loss on them.

And by how much is the consumption of washing machine detergent reduced?

If you use Calgon, it will not pay off. If you use another, cheaper one, then yes.

I have a filter installed in the washing machine. And you can see that the clothes are washed better, it smells nice, but the downside is that the washing machine works 5-10 minutes longer because the water flows into the washing machine slower. I bought this washing machine filter for PLN 20 and normally they cost over PLN 40

So is there any sense? A total of 20 not a fortune - I will look for the allegro and also buy - I will tell you whether something worked for me or not.

Another question - the washing machine takes it for washing - where softening is advisable, and for rinsing - where it is probably not needed - maybe except for the last rinse - so that stains do not form.

How long will this filter last for you?

There are also a washing machine filter for PLN 18, but it was about six months ago and I do not know how much they cost now. I bought this filter from me in Poznań in a store where they sell water filters. I have this filter for half a year. The filter softens the water and sweat to the washing machine, but be careful not to add too much washing powder. You just have to watch out for the dealers who sell these filters, for example, the photo you put in (these two washing machine filters) are not original because there is no foam there, which indicates whether it is worn. For me, it is partly used up, but I think it will be enough for maybe 3 months. Water is not medium hard and it used to be very hard.

adds the store where I bought:

http://www.sklep-rainbow.pl/index.php?p445,filtr-pralkowy-zmywarkowy

How does this foam work? Where to get it from? How will I know when they are used up?

I have quite hard water. For example, as on the filter, Brita writes that he can filter 300 l of water, I can use it half of it or less - because the beginnings of the stone in the kettle are already beginning and the tea looks non-original even after descaling.

Well, I have just ordered the ones from the photos - because they were PLN 18 each. Plus 0.5 kg of this polyphosphate to spare. And some ion exchange resin - I don't know what for - probably for experiments Such a curiosity - this ion exchange resin is very cheap. Even cheaper than polyphosphate. And I always thought it was a very expensive thing.

Well - we'll see what happens. At most a few dozen gold coins that I could spend simply on washing powder. But if I do the same financially, at least I will not poison the environment as much by using less powder.


There is no point in using it for the dishwasher, does it? I have the impression that the deposit contained in it performs this function much better and cheaper - because it is enough to add salt once in a long time.

I'll take a picture tonight or tomorrow morning where I have some signs of wear.

Added after 10 [minutes]:

All available in Poland, powdered water softeners in washing machines contain polyphosphates, be it Calgon, other antiKALK, or "filters". Whether you pour it directly into the washing machine or put a "filter" on the inlet, it will come out the same. It is important how much to use for a certain water hardness.
And wholesale sodium polyphosphate alone costs about 5 zeta / kg.
You want to sell you kg for a test (with information on the qualitative test and the place where I bought it). It is in an anhydrous form, i.e. a white loose powder that slightly clumps under the influence of air humidity.

I don't know how you will do with this resin.
When you prepare aqua water, you pour water over the resins in a bucket overnight. In the morning you can change the water to aqua.
The resins are regenerated with hydrochloric acid.

More like a saline solution ...

Arbites - but what is that white? Does it change color somehow or what? Can you buy it?

Serval - I'd like to buy with kg. I will try in different ways.

Will throwing such crystals into the washing machine have the same effect as running water through them?

Is sodium polyphosphate soluble in water or does the reaction take place at the interface between it and water?

It is soluble in water, it works by complexing Ca and Mg ions in a solution, responsible for water hardness, the so-called carbonate. It binds with these ions in a soluble and temperature-insensitive form, the bond is so strong that it almost "removes" them from the solution.
Here you have a pdf. description and analysis and safety data sheet
http://www.brenntag.pl/lista-produktow/widok-...ktu/?produkty[single]=502998&cHash=3ceeeb9470
It has the form of a white powder that you sprinkle directly into the washing machine, about a teaspoon of tea per wash.

Contact us if you are interested, about a kilogram of polyphosphane from the parcel will be 11 - 12 PLN.

ee, this is the foam, it is factory-inserted.
For me, the foam is a different color instead of white, i.e. it is worn out:

This foam is the sponge that holds these crystals. And the color shows the iron / manganese deposited in the water, it will brighten after an acid bath.

that is, it is worn out not?

As far as I know about the effect of polyphosphates (and I have been working with them for about 9-10 years), it will be used up when these crystals completely dissolve. And if you want to discolor, just take the sponge out and rinse it in a solution of citric or acetic acid. As a last resort, it may be an acidic toilet cleaner, i.e. one containing acid or kamyx. a pebble or another descaler for kettles.

You can degenerate it!

Technical hydrochloric acid 33% at a dose of 180 g per 1 liter of resin should be used for regeneration.
