Water Filters

everypenny

Hi guys.

Recently installed a domestic well and had the water tested.

The results were as follows:
Total iron 1.48 mg/l
Total manganese 0.80 mg/l


There's no organic material present and these are the only pollutants involved. The water is clear (absolutely no particles or iron visible even after being left to rest for a week), moderately soft and has a PH of 7.

We've been recommended different types of filter solutions, both in a 10x54 unit.

1. Crystal Right €1600
2. Ecomix A unit c/w volumetric valve control - €1305.00

I've read that each has its pros and cons depending on usage and whether the Iron is dissolved or not.

We'd want a flow rate good enough to provide water for up to four adults per day through a kitchen, utility, two bathrooms and an outside tap.

Any thoughts on which we should go for?

Hi EP,

did you ever put in a filter, if so which type? My circumstance is a bit different as we are on mains water but the quality is still poor here in Galway. I am looking to install a filter on the kitchen sink so we can drink the water in the house rather than using bottled water all the time.

aah yes

Hi everypenny,

I would factor out the information above from what is available and what is absent ...


1 New well drilled, hourly or daily water yield yet to be confirmed ?

2 Main problems - iron 1.48 mg/l (0.2 mg/l limit) manganese 0.8 mg/l (0.05 mg/l limit) moderately soft - 50 to 100 ppm ?

3 Supplier suggestions - Crystal Right €1600 / Ecomix A €1305

4 Flow rate required - 4 adults


The Crystal Right unit can be ignored, as the manufacturers of Crystal Right media, (WaterRight) do not recommend either CR100 or CR200 to be used on low hardness, i.e. less than 50 ppm hardness or 80 TDS conductivity, as it will dissolve.

Crystal Right is overly expensive to buy, to run and to service, it eats through large amounts of salt for no good reason, it is costly to re-service and re-bed the media once exhausted. It could be using 6 to 8 KG of salt every 4 to 5 days.

Ecomix is the modern replacement of CrystalRight (except for pH adjustment). At €1305, (odd figure) it is overpriced, it should be less than €1000 installed with 10 year cover. It could be using 4 to 5 KG of salt every 4 to 6 days.

Ecomix A or Ecomix C both would be fine (the C grade allows for higher colour removal in times of heavy rainfall). No issue with lower hardness, but then why get a media with softening and salt costs where the timer settings will probably be set for the iron levels and more frequent washes, wasting a lot of salt ?


The answer really has to be 42 litres of Lanxess S1567 media in a 10x54 with a Clack WS1CI valve control. Lanxess will polish away your level of iron no problem and manganese, no problems with low water hardness, except long wash cycles of up to 28 days, allowing for the iron value added to the hardness value on meter settings, still super efficient.

Lanxess would use less than a quarter the salt compared to the Ecomix unit and still much much less than the Crystal Right. Lanxess would have a 40 year service life with very little service needed maybe a mild check over once every 10 years. The Lanxess system in this example may use 5KG of salt every 2 to 4 weeks.

sorry to ressurect an old thread but im getting (obviously biased) information from Ecomix system supplier contrary to whats been said in the last post, perhaps 'aah yes' can comment? I am told that Lanxess is mainly used for softening but is somewhat effective at iron/manganese removal wherease Ecomix is specifically designed for this purpose. He agreed that Ecomix uses "slightly more salt" than Lanxess but Ecomix media will last longer and the additional cost of salt is minimal...
Thanks

aah yes

Hi PROJECT K,

It looks like you have been given a bit of wrangled info on the Ecomix.

Ecomix uses potentially A LOT MORE salt, it could be as low as 6 or 7 bags a year, but depending on settings and iron level, it could be 20 bags a year or more ?

With Lanxess generally, the salt use can be as low as 3 to 5 bags a year, with even a higher 7 or 8 bags in the more extreme cases with higher iron levels, depending on the levels. Lanxess can only handle a moderate level of iron and manganese, but there is more work to do beforehand to check on the water analysis, say levels of manganese etc, before considering the ideal media.

Ecomix actually does not last longer ! Check with the manufacturer code / spec / advice, and you will find out, even from the words of the mouth of the boss of Ecomix Andre Mitchenko that he advises changing Ecomix every 10 years.

Lanxess S1567 has a life of 20 to 30 years easily.

Aah Yes
