Water softening system Aqmos BM-32

Aqmos BM-32 water softener for households up to 3 people

Efficient product overview

The Aqmos BM-32 water softener was specifically designed for households with up to three people and reliably removes limescale through ion exchange. With an incoming water hardness of 10°dH, up to 3,200 liters of softened water can be produced per regeneration cycle. This ensures long-term protection of your plumbing and reduces detergent consumption.

Compact design and high-quality components

The system is housed in a robust cabinet with a removable lid. Inside is a fiberglass-reinforced (FRP) pressure vessel filled with durable ion exchange resin. The cabinet also serves as a regeneration salt container and can hold up to 40 kg of table salt.

The system is completed by the water volume-controlled valve BNT 1650, which is mounted directly on the pressure bottle and controls the regeneration process fully automatically.

How ion exchange works

At its core, the high-quality resin exchanges the calcium (Ca2+) and magnesium (Mg2+) ions in the water for sodium ions (Na+). This process effectively removes limescale and ensures soft water in the kitchen and bathroom.

The ion exchange resin is designed for a lifespan of over 20 years and remains permanently efficient through regular regeneration.

Intelligent flow control with valve BNT 1650

The integrated valve monitors softened water consumption via a water meter. Once the preset volume is reached, regeneration does not start immediately, but only at 2:00 AM. This optimizes the availability of limescale-free water.

Before regeneration, a reserve capacity is available to absorb any peak consumption. The factory preset adapts to your water parameters and consumption patterns.

Automatic regeneration for sustained performance

Once the resin is fully saturated with calcium and magnesium ions, the system automatically passes a concentrated saline solution (NaCl) over the resin. This rinses away the calcium ions and re-saturates the resin with sodium ions.

The resulting salt solution, including the dissolved hardness minerals, flows into the wastewater via a separate drain, while the integrated bypass carries on untreated tap water. This ensures an uninterrupted water supply during regeneration.

Security regeneration after inactivity

To prevent bacterial growth in the resin bed, the BM-32 automatically performs a forced regeneration after ten days without resin consumption. This safety measure ensures consistently hygienic resin.

Practical salt filling and maintenance

The integrated salt container holds up to 40 kg of table salt, which is sufficient for approximately three to four months, depending on water hardness and consumption. A float valve with a safety cartridge prevents the housing from overflowing.

Once the salt supply is depleted, it can be easily refilled. This ensures your water softener remains ready for use at all times, allowing you to enjoy consistently soft, limescale-free water.
