Key operating components of the water softener

BNT7650 control valve

The water softener is equipped with a BNT7650 series controller with a Polish-language menu, which makes configuration and later system operation easier. This solution is valued for stable, reliable operation and intuitive settings.

The valve head features a MIXING residual hardness valve, allowing precise adjustment of the outlet water hardness. It is a practical solution for users who want to match water parameters to the needs of the installation and everyday use.

PUROLITE C100-E ion exchange resin

The heart of the unit is polyspherical PUROLITE C100-E ion exchange resin. During the softening stage, calcium and magnesium ions are exchanged for sodium ions, so the water entering the installation becomes soft.

The ions responsible for water hardness are then discharged into the sewer during the unit regeneration process. This method of operation helps reduce deposit buildup and supports protection of the household installation.

2-stage pre-filter included

The set includes a 2-stage pre-filter with a reusable mesh cartridge and an antibacterial cartridge. The set is installed before the softener to improve the quality of water flowing into the unit and thereby protect the resin bed inside the softener.

Such a water filter plays an important role in the entire treatment system. It retains mechanical impurities and supports longer, stable operation of the unit. Although it is not a system such as reverse osmosis, an osmotic filter, or a reverse osmosis filter used for drinking water, it is an effective protective stage for the installation and the softener against solid contaminants.

Filter housing design

The housing features a 3-piece construction. This practical solution makes cartridge replacement easier, because to unscrew the housing you only need to unscrew the ring itself. There is no need to rotate the entire sump, as is the case with 2-piece versions.

Full pre-filtration process

1. Stage I filtration: Aquafilter FCPNN50M
   The reusable mesh cartridge is used to remove mechanical impurities such as sand, rust, or suspended solids. Its advantage over many other solutions is the ability to clean it and reuse it for water filtration.
2. Stage II filtration: Aquafilter FCPS20-AB
   The 10-inch cartridge made of AQUAFILTER polypropylene foam in Melt-Blown technology captures mechanical impurities such as sand, rust, and silt with an accuracy of 20 microns. BACinix™ nanosilver technology involves the use of nanosilver particles in the cartridge structure, which create an environment that limits the growth of microorganisms, has a bacteriostatic effect, and helps extend cartridge lifespan.

Benefits in everyday use

Soft water throughout the home means not only greater comfort, but also real support for installations and appliances. The softener helps reduce limescale buildup in pipes, fittings, heating boilers, and central heating systems, which can translate into more efficient operation of the entire system.

In practice, this also means better conditions for home appliances such as washing machines and dishwashers, lower energy consumption, and more effective detergent performance. Soft water is also more pleasant in contact with skin and fabrics, which is appreciated every day during bathing, washing, and cleaning.

Set contents

• WodaRO ECO 25 BNT MAXI water softener.
• 25 liters of PUROLITE C100-E ion exchange resin.
• BNT7650 volumetric control valve with a Polish-language menu.
• BY-PASS valve.
• MIXING valve for setting residual hardness.
• 2-stage pre-filter installed before the softener.
• Aquafilter FCPNN50M reusable mesh cartridge.

Additional important information

• PUROLITE C100-E ion exchange resin After passing through the carbon bed, the water comes into contact with the softening bed. At this stage, calcium and magnesium ions are exchanged for sodium ions. Ideally dechlorinated, safe, and soft water is discharged into the water installation. The “hardness” ions (calcium and magnesium) are discharged into the sewer during the unit regeneration process.
