The FLECK9100 water softener control valve, sodium ion exchanger, and FLECK9100 fully automatic water softener use a fixed bed sodium ion exchange softening method. When the fixed bed is running, the water flows through the sodium ion exchange resin layer from top to bottom, and the calcium and magnesium ions in the water exchange with the sodium ions in the resin, softening the raw water. The resin used is 001 × 7 strong acidic styrene cation exchange resin. After the sodium ion exchange resin fails, in order to restore its softening ability, sodium ion regenerators are used for regeneration, including both co current and counter current regenerators. The regenerator is generally a salt (NaCl) solution.
The Fulaik fully automatic water softener is mainly composed of a control valve, a resin tank, and a salt tank. The control valve can automatically complete all the working processes of the softener according to the set program. The resin tank is used to fill sodium ion exchange resin and serves as a container (i.e. exchanger) for softening and regeneration reactions. The salt tank is used to dissolve the saturated salt (NaCl) solution used in the regeneration of the softener.

General requirements for the installation of Fulaik water softeners:
1. The inlet pressure should be between 0.2-0.5MPa. When the water source pressure cannot meet the requirements, a booster pump can be installed to increase the inlet pressure. If the pressure is too high, a pressure reducing valve should be installed to control the inlet pressure.
2. The inlet water temperature should be between 5-45 ℃, and the power supply should be AC 200V/50Hz.
3. The water softener should be installed on a sturdy platform with unobstructed drainage nearby and sufficient space for operation and maintenance.
4. The working environment temperature should be between 5-50 ℃, and the relative humidity should be ≤ 95% (at 5 ℃).
