Equipments to process water from wells and brackish water,
suitable to treat up to 2.500 mg/l (low salinity) and 9.000 mg/l
(high salinity) of TDS, respectively.
It can be mounted in a small cabinet Mod. 4045500
Optional production capacity increase with adittional
membranes (1-4)
Options: Chlorine remover filter, silex filter, iron remover
filter, organic matter filter. Biocide doser, Bisulfite and water
softener for boilers.

RO Demineralisers Medium
Models 4DAXX00. Main Features:

Antiscalant doser instead of a water softener with salt.

Antiscalant automatic mixture preparation.

Backwash with demineralised water instead of feeding water.

Advantages due to the use of antiscalant:


Ecological: No brine from the water softner regeneration



Logistics and easy use: no need to stack salt bags and simplicity
Cheaper: antiscalant is cheaper than salt consumption
Expansion of the action capacity: wide espectrum
Balance in the ratio production/surface & reject/surface of the membrane
compared with the old existing equipments.

Models 4DAXX00. Example of anomaly
Just like a car, the models 4DA have two types of alarms to inform us about any
possible failure and its seriuosness.

Buzzer included to alert the customer about
the failures.

•
The equipment must recognize the
adverse conditions to assure a long
operational life.
The demineralisers are equipments
overlooked by the customer (is a non
productive equipment) and usually there
is not a preventive maintenance of these
installations.
The equipment will stop only if there is an
imminent risk to its operating life,
avoiding irreversible and expensive
damages.
The customer must be informed of any
anomaly (critical or not) without
decreasing the business.

Maintenance of Demineralisers 4DAXXXX
1.- Daily maintenance
2.- Every week
To check the level of chemical
product.
To check and to take note of
pressures and flows.
3.- Every 3 months
4.- Every 6 months
To check the condition of the filters (FS1
& FS2), if necessary they should be
changed.
To clean the small tanks of
anti-scalant and backwash
water.

Example of calculation of Antiscalant vs Water Softener
Antiscalant dosage
Water softener 2x100 litres
Consumption of antiscalant product:
Salt Consumption:
– Daily need of water: 21 m3 at 70 ºHF
(39,2ºHD).
– Necessary regeneration of the water softener
every 9 m3
– Number of regenerations per day: (21m3/day)
/ (9m3/ regeneration) = 2.3 regenerations /day
– Consumption of salt per litre of resin in every
regeneration: 0,2 kg/Litres of resin
– Consumption of salt in every regeneration: 0,2
kg/Litre of resin x 100 Litres of resin = 20 kg of
salt per regeneration
– Salt consumption per day: 2.3 regenerations /
day x 20 kg of salt/regeneration = 46 kg/day
– Salt consumption in the same period of
time (124 days): 46 kg/day x 124 days =
5. 704 kg = 228 sacks of 25 kg
– Daily need of water: 21 m3 at 70 ºHF
(39,2ºHD).
– “High” dosage of product: 5 mg/L = 5 g/m3
– Daily product consumption: 21m3 x 5 g/m3 =
105 g/day = 0.105 kg/day
– 1 carafe 10 L = 13 kg
– So 1 carafe of 10 litres of antiscalant will
last: 13 kg / 0.105 kg/day = 124 days

Example of calculation of Antiscalant vs Water Softener
Conclusion: In 124 days of use:
5.704 Kg of salt
=
1 bottle of 10 L (13 Kg)
Make yourself your calculations:
Price/kg Salt x 5.700 kg salt = Euros spent on salt
versus
PVP 10 L Antiscalant carafe = 189 ,00 Eur
