Fulai 2900 industrial water softener dual tank softening water device fully automatic water softener control valve, suitable for dual tank systems without the need for external valve control.
Structural features: The piston is arranged horizontally, with two pistons, one controlling the regeneration program and the other achieving water inlet and outlet switching. The valve body material is lead-free brass, and a hard water bypass piston can be optionally equipped. Paired with a dual tank system or a multi tank system, it can be achieved without the need for additional valves. Suitable for boiler water softeners and other industrial water softeners.
1、 Working principle:
The hardness of water is mainly composed of cations such as calcium (Ca2+) and magnesium (Mg2+) ions. When raw water containing hardness ions passes through the resin layer inside the exchanger, calcium and magnesium ions in the water are adsorbed by the resin, while sodium ions are exchanged and released. The water flowing out of the exchanger in this way is softened water with removed hardness ions. When the resin adsorbing calcium and magnesium ions reaches a certain level, the hardness of the effluent increases. At this time, the water softener automatically regenerates the failed resin, using a higher concentration of sodium chloride solution to pass through the failed resin and restore it to sodium type resin. The system is an integrated device consisting of resin tanks, salt tanks, and controllers. Installed centralized control valve from FLECK company in the United States to achieve program control operation and automatic regeneration; Adopting the siphon principle for salt absorption, automatic water injection for salt hydration and concentration ratio, without the need for auxiliary equipment such as salt pumps and salt dissolution.
2、 Features of Fulai water softener:
Automation: This equipment achieves automation of ion exchange and resin regeneration processes through program control devices.
High efficiency: The design of the water softener is reasonable, allowing the resin to work effectively and the exchange capacity to be fully utilized.
Labor saving: No need for dedicated personnel to operate, easy to install.
Water saving: The water production rate is over 98%.
Energy saving: Due to the use of siphon principle, regeneration does not require a salt pump, and the equipment power is only 3-135W.
Easy to adjust: The regeneration cycle and time can be adjusted as needed.
Tank anti-corrosion: The tank is made of fiberglass, stainless steel, and steel lined plastic materials to avoid resin contamination.
3、 Fulai water softener working procedure:
1. Water supply: Untreated water passes through the resin layer, undergoes an exchange reaction, and produces soft water.
2. Backwash: Water enters from the lower part of the resin layer, loosens the resin, and removes fine impurities.
3. Salt water regeneration: Using high concentration salt water (NaCl) to flow through the resin, the failed resin is restored to sodium type usable resin.
4. Rinse: According to the process of water supply, rinse excess salt solution and regenerated calcium and magnesium ions through resin.
5. Water injection: Inject water into the salt tank to dissolve the salt for the next regeneration.
