Dear partners,
Thank you for having chosen the water treatment stations with ion exchange resins aquaPUR
distributed 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. STATION 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 softening station uses an ion exchange resin through
which retains calcium and magnesium ions in water.
During regeneration, the stations do not supply treated water, so the water that reaches the consumer
is untreated. Water should be used at all or as little as possible during this time to protect the heating
systems. Therefore, regeneration is automatically set at night and manual regeneration should be per-
formed when very little or no water is used.

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
