Dear partners,
Thank you for having chosen the water treatment systems with ion exchange resins aquaPUR
manufactured by SC Valrom Industrie SRL.
Prior to utilization, please read carefully these guidelines for installation and operation.
For other information please refer to the site www.valrom.ro or www.aqua-pur.ro
1. SYSTEM TYPES AND TECHNICAL CHARACTERISTICS
The treatment/filtering technology with ion exchange resins is one of the simplest and most convenient
methods to improve water quality. The water treatment system with ion exchange resins is improved by
adding other agents aimed to reduce other pollutants from water as for instance iron, ammonium.
The mounting and operation of the following treatment systems is shown in this handbook:
- <aquaPUR>SOFT softening stations based on ion exchange resins,
- <aquaPUR>MIX treatment stations – a mix of various filtering agents.
<aquaPUR> SOFT softening stations
Water hardness is the frequent cause of defects in the heating installations, especially, stations,
boilers, electric household appliances (washing machine, flat-irons, coffee machines etc.) which lead to
additional expenses and even a depreciation in comfort. Another effect of the hard water is a reduced foam
formation of detergents and soaps which leads to an increase in the house maintenance costs. Other
effects of hard water are those of an aesthetic type such as deposits on sanitary appliances and those
related to comfort such as clothes depreciation, skin and hair drying.
Softening through an ion exchange is the simplest and most convenient method to reduce water
hardness. Ion exchange resins attract and retain calcium and magnesium ions diluted in water to be
replaced with sodium ions. When the water volume is consumed between two regenerations, the resin
will be regenerated with sodium chloride solution (brine). The regeneration cycles are: Backwash, Brine
draw, Rinse and Refill
<aquaPUR> MIX treatment station
<aquaPUR> MIX treatment stations achieve a reduction in concentration of several substances based on
only one step in Ecomix filtering agent.
The filtering agent from MIX stations is a mix of agents that includes ion exchange resins with
synergic properties. Inside the treatment system, the filtering agent bed is stratified on levels that work in a
complementary way, reducing hardness from water, iron, manganese, ammonium and organic
substances. The medium regeneration is carried out with a sodium chloride solution in an identical way
as that performed by softeners.
