New generation system with easy-to-program metered valve. This system is composed of a PRFV bottle with top and bottom distributors and polyethylene cabinet.
- Denver 959D valve, electronic programmer, delayed regeneration.
- Hardness mixer included.
- Connection 1".
- Floating valve included in the cabinet.
- By-pass included in the system.
By-pass valve is included in all Denver® water softeners.
In hard water areas, Scale and Scum come into your home because of the hardness minerals in your water supply. Scale coats the inside of your pipework with a hard, heatproof layer that makes your heating system burn more fuel, and Scum kills the bubbles in your bath and makes you use extra washing powder.
How Water Softeners Work
In brief, water softeners are designed to remove calcium and magnesium (the cause of scale and scum) from hard water. They are intended to treat the whole house, so are installed where the water supply enters the premises.
Hard water pumped into your home passes through a bed of resin crystal beads in the unit which capture the lime scale and minerals by an ionising process. When the beads become exhausted, they need to be regenerated by flushing through a salt water solution.
Ion Exchange softening is the only water treatment that effectively removes hardness salts (Calcium and Magnesium). These salts are replaced by sodium, whose higher solubility avoids salts incrustation. Feed water passes through a resin bed inside the softener vessel. In this moment hardness salts are captured by the Ion Exchange beads. When resin is completely depleted it should be started a regeneration. Regenerations are commanded by the control valve.
Water softening happens through a process called ion exchange, which uses an ion exchange resin. The resin comprises of tiny polymeric beads which are specially formulated so that they can be charged with certain ions. Calcium and magnesium, the causes of scale and scum from hard water, are referred to as ions, and as water passes through the resin, the calcium and magnesium ions swap places with the sodium ions on the resin. Sodium salts, unlike calcium and magnesium, are highly soluble so sodium does not cause scale or scum. When all the sodium ions have been exchanged for calcium or magnesium, the resin must be regenerated by recharging it with sodium ions. This is done by flushing the resin with salt solution (brine).
