8. How we arrived at the point?
5 typical problems of Ukraine’s well water:
• Iron
• Manganese
• Hardness
• Ammonia
• Tannins, Natural
Organic Matter
(by COD)
Insides of a dishwasher that
has run on raw well water
9. If we use conventional technology…
Raw
water
1. Catalytic media (Birm, MTM, Greensand) for Iron removal
2. Cation exchange resin for softening
3. Activated carbon for tannins removal
4. Zeolite for ammonia treatment
• Detailed water analysis is required
• Deep knowledge of water chemistry
and experience are necessary
• Limited effectiveness
• High cost
• Tricky in operation
10. IIff wwee uussee EECCOOMMIIXX……
• Market’s best solution for
Manganese and Iron
• One filter for 5 impurities.
No detailed water analysis

traditional softener.
• Proved effectiveness
for the majority of waters
worldwide
• Lower cost and higher gain

18. ECOMIX®
is a composition of FIVE
materials of different origin and
properties
Includes two patented
adsorption components
invented by Ecosoft.
19. Inert resin removes oxidized iron and ensures even flow
distribution in backwash
Modified sorbent FerroSorb binds Fe(II), provides formation of firm Fe(III)
oxides layer and autocatalytic adsorption of iron and manganese compounds
Modified sorbent HumiSorb retains
NOM through electrostatic interaction with
charged groups and hydrophobic binding
with aromatic fragments.
Cation exchange resin
exchanges Ca and Mg and residuals of Fe
(II).

21. Ecomix includes a tailor-made iron and
manganese sorbent FerroSorb
Cross-section of
FerroSorb
Outer active layer of the FerroSorb
allows to efficiently remove IRON
and MANGANESE from water
23. FerroSorb in Ecomix works to efficiently remove
iron and manganese
Common cation exchange resins take
iron too, but due to poor regeneration
become exhausted very fast
24. • FerroSorb is regenerated by Surface
Scouring Mechanism (SSM) in fluidized bed
• Other resins are exhausted irreversibly
Well-known oxidation-filtration is not applicable to
FerroSorb, because FerroSorb provides totally different
mechanism of action:
Adsorption → Oxidation → Layer Formation →
Multicycle Autocatalytic Sorption
25. Ecomix includes a tailor-made HumiSorb
that reduces level of Tannins and color of water
fresh HumiSorb HumiSorb after
Tannins adsorption
27. • HumiSorb is not just an anion exchange
resin
o Very efficient for aquatic tannins
o Regeneration with Cl-
• Due to irreversible binding of tannins
common anion exchange resins become
exhausted very fast
28. Ecomix production
technology is a know-how
of Ecosoft:
•Provides activation of the
surface modifiers in FerriSorb &
HumiSorb
•Homogenity
•Consistent quality and
composition
•Ecomix production is
ISO 9001:2009 certified
29. ECOMIX® is manufactured in:
Ukraine
(for ex-USSR
countries)
Germany
(for EU countries and
the United States)
Supplied in 25 L (0.9 ft3) and 12 L (0.4 ft3) bags
36. Genuine

Generic mixture1 Generic mixture 2
Mixtures of ion exchange resins that are sold at
several times the price of their ingredients
• Visual differences
• Generics do not contain FerroSorb and HumiSorb
• Not homogeneous → no guaranty for stable
product composition
• Become exhausted after iron sorption
37. Caution! Generics are dangerous
1. Lower retention capacity for
iron and hardness
2. Adsorption capacity
deteriorates after each
service cycle, generics do
not regenerate completely
3. There is a risk of releasing
retained manganese!

43. Exchange capacity and regeneration
Ecomix service cycle is neatly calculated from its ion exchange
capacity:
• ECOMIX A 0,75 eq/l = 15 200 grains/cft*
• ECOMIX C 0,65 eq/l = 13 100 grains/cft*

For successful operation ensure
adequate regeneration
50. Consequences and causes of poor regeneration
Accumulation
and aggregation
of trapped fines
Excessive volume of media
Insufficient or excessive
backwash flow rate
Too short backwash time
Loss of ion exchange
capacity
Insufficient brine volume and/or
concentration
Insufficient brine contact time
Poor/restricted brine percolation
due to buildup of fines or channel
forming in the bed
52. Restoring the media after improper use
1. Interval backwashing with 20-30 second periods of rest
2. Air scouring the bed (5-10 minutes)
5 - 10 times
3. Making brine in the filter tank (1,3-1,5 kg of salt per 10 L of the
media)
4. Air scouring the bed while resting it in brine (15-20 minutes)
5. Interval backwashing with 20-30 second periods of rest until the
brine is completely flushed away
3 - 5 times
